Welcome to StarTalk, your place in the universe where science and pop culture collide.
StarTalk begins right now.
This is StarTalk.
I'm your host, Neil deGrasse Tyson, your personal astrophysicist.
And today is yet another edition of Cosmic Queries.
And I think this one is titled Galactic Gumbo.
Is that right, oh co-host Chuck Nice?
Yes.
Yes, it is.
Galactic Gumbo.
I love that. I love that.
Gotta love that. Guarantee.
You know, I'm just on the same old cone.
Put it in there. And then I put it in the cayenne pepper.
Cayenne pepper, that little dark matter. Little dark matter.
Little dark matter?
Little dark matter, little cayenne pepper.
The black hole?
Little black hole. And then I put in a little bit of quasar. A little bitenne pepper. A little black hole. A little black hole. And then put in a little bit of quasar.
A little bit of quasar.
Galactic gumbo.
So if you were white and weighed 300 pounds more and were dead, you'd be a splitter.
I'd be a splitting image of Paul Perdom.
Paul Perdom.
Splitting image of Paul Perdom.
Guaranteed.
Chuck, great to have you.
Love you on Cosmic Queries.
Of course.
Let's do this galactic gumbo.
Yeah, and of course, you know, we always glean our queries from all across the internet,
no matter where we are found and in what incarnation.
And we always start with a Patreon patron
because they support us financially
and very much like your elected officials,
we too can be bought.
Is that right?
So, yeah, so just to clarify.
Just to clarify.
So we experiment on this show in ways that would not otherwise be possible from just pure ad revenue.
Yeah.
Because there are things that would be risky.
There are ideas we have that sponsors, they don't believe that it'll work.
We also do a few humanitarian things.
And so that sort of front money
that we get from the Patreon folk.
Patreon folks.
And we have a new outlet
called StarTalk All Access
for those of you out.
So you can find that
at StarTalkAllAccess.com,
which is another revenue stream.
And all these things
help us grow the StarTalk universe.
Trying to bring the universe
down to earth.
There you go, baby.
Right.
So our Patreon patron is Elaine Griffith, who says that-
We know where she's from?
She's from Oakland, California.
Oakland, California.
She says, hi, Neil.
This is Kendra from-
Oakland, that's where Batman is from, apparently.
Superman versus Batman.
Like Gotham City and what's the other one?
Metropolis.
Are across the bay from one another.
Oh, okay.
So it's Oakland and San Fran.
Right.
So Wayne, it makes sense because Wayne Industries, of course, like huge company, maybe a tech
company.
Maybe a tech company, yeah.
So it was just thought I'd tell you that.
That's very cool.
So Kendra from Cali, as in Oakland, California, Elaine Griffith
is my nom de plume.
First of all, I dare one of you
to sing this out loud to the
tune of Sexy Back, which
is, we're bringing quirky
back. Without
them, Adams don't know how to act.
We got some
hadrons gonna make them smack.
We found a boson now, now who's the man?
Uh, uh, test it in the eye now
Okay
So there you go
So that was some hadron smack
Hadron smack is what she said
So, hey, guess what, Elaine, I did it for you
Yeah, I couldn't have pulled that one off
So I'm glad we got our boy in the studio for that
And then here's what she wants to know from you, Neil
Why didn't all the matter and anti-matter created by the big bang So I'm glad we got our boy in the studio for that. And then here's what she wants to know from you, Neil.
Why didn't all the matter and antimatter created by the Big Bang cancel each other out, leaving nothing but energy?
Ooh.
Wow.
Ooh.
Look at that.
Ooh.
Yeah, we take a lot for granted just living in this universe.
Right. Turns out that for every bit of matter in this universe, okay, there are, when all the matter was created, it left over photons.
Okay, so let me say that a different way.
You, at the beginning of the universe, there was this hot cauldron of matter and energy moving back and forth between one another.
According to E equals MC squared.
E for energy.
M for mass.
Yeah, mass.
Okay, so that equation allows you,
under the right conditions,
to freely transform one into the other.
Nice.
So, just to tell you how this works, if you take energy and convert it into matter,
you don't just get regular matter,
you get equal amounts of matter and antimatter.
Right.
Unlike your data plan with your phone carrier,
minutes in your data plan.
Do not transfer back and forth equally.
That was as obscure a reference to the universe
as I have ever heard.
Right.
Can you hear me now, universe?
Can you hear me now?
All right.
I'm going to stop.
Go ahead.
So the way that equation works, you take a pulse of energy, convert it into matter.
You get antimatter and matter in equal amounts, equal and identical opposite amounts.
Then the matter and antimatter hang out for brief moments of time, and they recombine and make pure energy again.
So this back and forth requires equal amounts of matter and antimatter.
So as the universe cools,
and the energy isn't high enough to make particles out of it,
we should be left with an entire universe of just energy.
Right.
No matter at all.
Right.
Okay?
Because once the energy of the light, the photons,
the pulses of energy drops below the energy necessary
to make the lightest particle,
there's no more particles to make.
You're just a low energy photon.
Right.
That's all you got.
That's it.
And you can never aspire to become anything other than a photon.
Oh, I feel so bad.
No, no.
It's another form of energy.
You can never become matter.
It's a caste system at this point.
What a shame.
I didn't know you get all emotional about this.
No.
I could have been somebody.
I could have been somebody.
So here's what happened.
I could have been somebody.
So here's what happened.
In the very early universe, there was an asymmetry in the matter and energy.
For every 100,000 particles of antimatter,
oh, did I say 100,000?
I don't mean that.
Sorry.
For every 100 million. Okay.
10 to the eighth.
Every 100 million particles of antimatter, 100 million and one particles of matter were made.
Oh.
Uh-oh.
Symmetry in the early universe was broken.
Ah.
By that little bit.
Just that tiny. You wouldn't even notice that little extra one until like in a dance, a dance
off, your dance partners start peeling off. Right. You take off this pair. Right. Everybody thinks
they got a pair. Right. And you just keep doing this. Right. Until you're left with one dude,
just break dancing in the middle of the party. Nope. That guy come from from? Right? With nobody to mate with. Right. Okay? And that one is left.
And so our universe is made of matter and not antimatter and not pure energy because of that one asymmetry.
And we know it happened.
We have a very good idea of when it happened in the early universe.
We don't know why.
Oh.
Yeah.
Nice.
Yeah.
It's just one of the mysteries of the universe.
Mystery of the universe.
I hate to sound cheap about this, but I recorded a video series.
Okay.
With a great courses company.
Called The Inexplicable Universe?
The Inexplicable Universe.
You know how I know that?
Wow.
Because I have it at home.
Oh.
Yes.
Very nice, Chuck.
Yeah.
And I didn't even give you that copy.
You did not give it to me.
You bought that thing.
That's right, I did.
Oh, my gosh.
Well, thank you. Well, you know, that's that copy. You did not give it to me. You bought that thing. That's right, I did. Oh, my gosh. Thank you.
Well, you know, that's how I do my homework.
It beats reading.
Watching the videos.
I'm like, let me just get Neil and...
And you don't want to sound like a complete idiot.
Right, exactly.
That's how I do my homework, man.
I could, you know, but go ahead.
Thanks for telling me that.
So in the inexplicable universe, one of the topics is this great asymmetry between matter
and antimatter in the universe.
Right.
And so I tell you how we come to learn that that's the case.
But I don't tell you why that's the case because it's inexplicable.
We don't know.
And hence the title, Inexplicable Universe.
Yeah, exactly.
As opposed to the next sequel, which will be the Totally Explainable Universe.
Yes.
But that's what all videos are.
Exactly.
Yeah, that's every single video.
That's what wiki pages are for.
We call that Nova.
Exactly.
No, seriously.
I'm not even joking.
All right.
Well, that was awesome.
Hey, Elaine, what a way to kick off the show because that's really good stuff.
Hey, let's go to Gregory from Bar.
Wait a minute.
Bastrop, Texas? Bastrop, yeah. Bastrop, Texas. Yeah, it's in West Texas. Bastrop. West Texas? Let's go to Gregory from Bar. Wait a minute.
Bastrop, Texas?
Bastrop, yeah.
Bastrop, Texas? Yeah, it's in West Texas.
Bastrop.
West Texas?
It's in West Texas, yeah.
Never heard of it.
Bastrop.
I think it's in West Texas.
Okay.
Yeah, yeah.
I mean, yeah.
I've been to that town.
Really?
Yeah, I've been there.
Bastrop?
Bastrop, yeah.
Okay.
All right.
Sounds like a big town.
Well, look.
Hey, listen.
It's a destination, I suppose, for somebody.
For somebody.
I'm not going to hate on Bastrop.
I don't know anything about it, right?
Hey, Neil.
It's Greg. It might be Central Texas.
It might be Central?
Yeah, yeah.
Okay.
Hey, Neil.
It's Greg from Bastrop, Texas.
I've been thinking about this for a while, and it's actually a part of a book that I'm writing.
Nice.
Okay.
So you know when a glass breaks because its sound hits a specific frequency.
Okay, so it's like that Ella Fitzgerald old time commercial.
How old are you, dude?
Old enough to remember that.
I don't know who the product was, but I just remember they would put a speaker next to a glass and it'd be like,
we're going to see if Ella Fitzgerald can break this glass.
And the only reason I remember is because Ella Fitzgerald was a friend of my grandmother's.
Oh, okay.
All right.
She'd be like, ah, and then the glass would start to vibrate and shatter.
So what happens is you can break glass with a frequency of sound that goes through it,
or you can just smash the glass.
Okay.
To be clear, that would not be the only way to break a glass.
But the way the question was posed is, this is how you break glass.
No, no.
You can just step on it.
Right.
You can just break it.
So what happened in any Jewish wedding?
Exactly.
Just step on it and mazel and now your life is ruined.
Right.
So, but he says this.
What if the strings in string theory making up the universe are vibrating at a specific frequency?
And that frequency is what determines the laws of physics in the universe,
maybe each universe making up the multiverse has its own unique frequency,
and that could be the key to traveling to another universe.
He has made many assumptions in this.
It's good.
I love it.
I like it.
It's good.
It's really cool.
Now, let me first preface this by saying I don't claim string theory as my center expertise.
Okay.
So I'll go as far as I can in responding to that question.
All right.
First of all, the vibrations of the strings in string theory, they are what is the manifestation of the universe we know.
Okay.
You vibrate them one way, you get an electron.
Right. You vibrate them another way, you get a particular species of quark. Okay. You vibrate them one way, you get an electron. Right.
You vibrate them another way,
you get a particular species of quark.
Okay.
You vibrate them another way, you get a...
So all of these vibrations come together
in this symphony we call our universe.
Nice.
What I do not know is whether the vibrations of the strings
are also implicated in the laws of physics themselves.
Okay.
I just don't know.
Right.
We had to bring somebody in for that.
Yes.
But if they are, I think it's a brilliant premise.
He said he's writing a book.
I assume it's a science fiction book.
It would have to be.
Yeah, yeah, yeah.
It would have to be.
I'm just saying.
I mean, no disrespect to Greg, but it would have to be a science fiction book.
I think it's a great and fertile idea that what you might do is you go into some vibration room, let's say, okay?
And it would have control over the vibrations of your strings in such a way that you would create a different symphony of vibrations that are the vibrations of another universe.
Nice.
And because in the multiverse, other universes have slightly different laws of physics.
We expect that to happen.
And because in the multiverse, other universes have slightly different laws of physics.
We expect that to happen.
Quantum physics clues us into how and why that should be the case.
Right. So if you needed a way to sort of get somewhere, maybe, yeah, give yourself a new vibration.
Oh.
A good vibration.
What?
What?
I was about to say Yeah
Good
Good
Good
Alright
Yo that's great
Hey Greg
Great
Great
Are you mixing two songs there?
No
You were mixing
Goodbye Braces
So that's Rolling Stones
No no no
No that was
Marky Mark
That was Beach Boys
Oh Beach
Oh you're talking to Marky.
Come on, come on.
That's what I'm saying.
The vibrations.
Oh, yeah.
Come on, come on.
Good vibrations.
Isn't that called good vibrations?
Yes, you're right.
It is.
I totally forgot about that song.
That's what I'm saying.
Oh, yeah.
Were those other songs called good vibrations?
I think the Beach Boys was good vibrations as well.
Good, good, good, good vibrations.
Okay.
Yeah, I'm pretty sure.
More than one song in the universe.
Yeah, there you go.
Good vibrations.
So it'd be cool if you just, so your transporter room would be a place where they differently
vibrated.
Put the strings in different ways.
Put the strings in different ways.
Wow.
So take it and run with it.
Yeah, go ahead, man.
Invite us to the premiere of the movie.
Yeah, good luck with the book. And right, yeah, we Invite us to the premiere of the movie. Yeah, good luck with the book.
And right, yeah, we want to be at the premiere of the movie.
Yo, super cool.
All right, let's move on to Dawn of the Dave from Instagram.
Just gives us that.
He doesn't give us where he's from or anything like that.
From Instagram.
From Instagram.
All right.
By the way, every Instagram post should have a photo, right?
Was there a photo attached to this?
I'm sure there was, but we probably just took the text.
The text, okay.
Dawn of the Dave says, if scientists, and I'm going to change this to if you, I'm going to personalize this,
had access to 100% of the world's computing power, what would you like to focus on so every every possible um
data bit okay so let's go going to be pointed at this one thing so let's like it to be let's uh
let's go back to archimedes okay who. Who said, upon understanding
how levers work,
give me a place to stand
and I can...
Watch from there.
I don't know Archimedes.
You don't know his famous quote?
I don't know his famous quote.
Give me a place to stand
and I can watch TV.
Watch,
because I like to watch.
Give me a place to stand and And I can watch TV. Watch. Because I like to watch. Give me a place to stand and I can move the world.
Ooh.
I like that.
Yeah, that's perhaps his most famous quote.
I did not know that.
So give me a place to stand.
Okay.
And I could move the world.
Right.
And so, okay.
And in the era of classical physics, it was imagined that if you knew, classical physics, 19th century classical physics.
Okay.
If you knew the position and momentum of every particle in the universe in this moment, you will know all future history of the universe that follows.
Wow.
Okay.
Now, I got to tell you, you lost me on that because just by knowing every position of
every particle.
In the universe.
Oh, because then you would know the movement of every particle from that point.
From that point.
And from that point, so you would be able to, okay, never mind.
I'm getting excited because you can see the light bulb just went off.
Okay, this is what happens when the light bulb.
Chuck just had a mental orgasm.
Yes, like I did, right?
It was great.
It was like Oprah climbed inside my head and was just like, you get it now.
So, go ahead.
All right.
So, because if you know that moment, then you'll know the next moment.
Right.
And then all the particles interact with one another.
Exactly. And you get the next moment. So, then there's nothing unknown for the future of the universe. So- Every single moment from that point forward is knowable because you know exactly.
In principle, this is what was proposed. And this is not any different from, let's say you have a
pool table and the balls are all in motion in a given instant.
Right. And then you can say, I will now predict for the future what balls will go in, what pocket
and whatnot. Right. And then, because at that point, if all the balls are in motion, it's a,
it's a matter of simple geometry. Correct. Well, physics. Yeah. Yeah. Both. Right. And so the
interesting thing about that is you, each ball affects another ball.
In that case, not gravitationally, but I hit you.
You could hit two other balls before you go in.
Right.
And so that was the idea.
Right.
Right.
And then you're taking into account transfer of energy, momentum, all these things, but you know them all, so it doesn't make a difference.
Exactly.
Right.
Exactly. So what I would do is try to compute. You load up the position and momentum of every particle in the universe into this supercomputer and then be able to predict all future movement of everything in the universe.
Here's the problem that we learned in the 1920s.
Okay.
This is a little thing called quantum physics.
Where the universe in the quantum is not deterministic right it is probabilistic right
so it doesn't respond the way it would in the physical universe in the in the deterministic
universe right so it puts a random element to it that prevents you from knowing with certainty what tomorrow will be just for knowing about today.
Right.
Yeah.
Because even though the known is known, the unknown is always unknown.
Unknown.
In the quantum.
In the quantum.
Ooh, very nice.
But nonetheless, I would go through that exercise and resurrect this old notion that – so that would be the universe without quantum physics.
Sweet.
Yeah, so if I were to program a universe in my computer,
that's the one I would program,
and I would just check it out.
The quantum-free universe
for which I know all of future history.
Chuck, we got to take a break?
Yes.
This is StarTalk, Cosmic Queries Edition.
Galactic gumbo.
That's right.
They're on team.
All right, we'll see you in's right. They're on team. All right.
We'll see you in a moment.
They're on team.
We're back.
Star Talk.
Cosmic Queries Edition.
I'm Neil deGrasse Tyson.
Your personal astrophysicist, Chuck Nice.
Hey, Neil.
Chuck.
You're tweeting Chuck Nice Comic?
Chuck Nice Comic.
Thank you, sir.
That is correct.
Dude, I like it.
Anytime something happens in the world, I go to your Twitter stream and you're on top of it in some way or another.
Yeah, I like to.
Either politics or somebody says something stupid.
I like getting a little dig in there.
You're digging in.
I like to dig in there just a little bit.
Yeah, I follow you.
Yeah, I follow you too.
And I don't follow many people, just so you know.
I know, I know.
I find out, I always know when you talk about me ever on Twitter
because my Twitter goes crazy.
I'm just like, what the hell?
What's going on?
Oh, you mentioned, you said something like, Chuck's learning astrophysics every day.
I might just turn the reins over to him.
I'm just like, no!
Please don't say that!
I did say that.
I freaking said that on Twitter.
I'm like, please!
Do not say that!
All right, so what do you have?
Cosmic queries.
Let's jump back into it.
We got a bunch of-
Galactic gumbo.
Galactic gumbo.
Give me a dose of dark matter.
That's right.
A little dose of dark matter on that.
That's right.
A little air too fat on the universe.
This is Melissa Wolf from Facebook.
Facebook. Facebook. And she is writing on her Facebook account from Chino Valley, Arizona.
Right.
Melissa says this.
I'm very curious.
Arizona has two of the most famous holes in the world.
Okay.
I'm not sure where this is going.
No, no, no.
It's got the Grand Canyon.
Okay. That's a hole in the ground. I look at, no. It's got the Grand Canyon. Okay.
That's the hole in the ground.
I look at that more of a ditch than as a hole.
Okay, okay, fine, fine.
And it's got the Meteor Crater.
Oh, okay.
Yeah, also known as Barringer Crater.
And is that the crater, the mass extinction level event crater?
Is that that one?
That's what you would say if you were aware of that hit.
That's what you would say if you were aware of that hit. That's correct.
It's a crater.
Like, whatever you would do in there, you would gone.
It's almost a mile wide, and it can sink a 60-story building from its bottom to the top.
Wow.
So it's the best preserved crater in the world.
All right.
So now, here's what I'm going to ask you.
And we haven't even got to her question yet.
I know we're going to get to your question, Melissa. Since I heard she's from Arizona, I got to put Arizona in the world. All right, so now here's what I'm going to ask you. And Melissa, I know we're going to get to your question.
Since I heard she's from Arizona, I got to put Arizona on the map.
Now that you brought up this crater, it's a mile wide, which, I mean, that's—
It's really a mile wide.
It's really a mile wide.
I mean, so the impact, just phenomenal, incredible.
We know.
However, now I got to ask you this.
Just to be clear, it was not the one that took out the dinosaurs.
Right, I'm just saying.
This is small potatoes. Right, this is— Compared to that, it was not the one that took out the dinosaurs. Right. I'm just saying. This is small potatoes.
Right.
This is right.
Compared to that.
That was the size
of Manhattan or something.
Oh, no.
Size of Mount Everest.
Size of Mount Everest.
That's what it is.
God.
Yeah.
That is mind-boggling.
But,
so that crater,
this meteor
hit ground,
right?
Yes.
Okay.
Now, here's what I want to know.
Yeah.
All right.
What if it hit the ocean instead of the ground, that same impact?
Okay.
So, it turns out if an asteroid is big enough, it don't matter ground or it just doesn't
matter.
It doesn't matter.
So, in the following way, Suppose an asteroid is 10 miles across.
Okay.
Okay?
Wow.
That is, some are.
That is larger than the depths of the oceans.
True.
So it'll just spread the water.
It's like dropping a brick into a puddle.
Into a puddle, exactly.
It's like dropping a brick in a puddle. Exactly. Itdle, exactly. It's like dropping a brick in a puddle.
Exactly.
It doesn't make a difference.
It doesn't make a difference.
You're going to hit the ground, and yes, you'll create great tsunamis.
Yes.
That will be your biggest problem.
Problem.
Right.
Exactly.
The tsunami will actually be refreshing compared to the aftermath that follows.
Exactly.
I got you.
And the climate change and all that would unfold.
Okay, cool.
Cool.
But it is true.
On the ground, it would make a small enough one.
Right.
That one was the size of the sphere at the Rose Center for Earth and Space.
Okay, got you.
You can measure that up and figure that out.
Wow, and that's tiny compared.
It's tiny compared to Mount Everest.
Oh, my God.
Oh, yeah.
Oh, yeah.
There's a shooting gallery out there.
Everest. Oh, yeah. Oh, yeah.
There's a shooting gallery out there.
So that one, if it hit the ocean, it probably
would
not have reached the bottom of the ocean.
The ocean was really deep. Where the Titanic
sank, it was like miles
deep. But all that energy
would then get deposited into the oceans.
Then you get a tsunami that would come in very
far inland. Gotcha.
Okay, cool. All right, so Melissa.
We would have taken out the coastal cavemen.
We would have disrupted the shipping lanes.
Oh, dear, Trog, I do believe we're going to lose our beachfront property.
Trog.
Lothar, my friend, do you have any property that isn't beachfront?
This was 50,000 years ago.
We was totally in caves back then.
Oh, my goodness.
Fellas, grab your women by the hair and let's get the hell out of here.
We've lost our beachfront property.
Okay, here we go.
Again, we'll get to her question in a minute.
We'll get to you, Melissa.
We're getting to you, Melissa.
I got one.
Wait, wait. So I have to boast, Melissa. I got one. Wait, wait.
So I have to boast of something.
All right, go ahead.
One of my proudest moments writing was I wanted to come up with a female caveman name.
Right.
Because all the names we have are male.
Yeah, right.
Trog.
Trog.
Lothar.
Lothar.
These are guy names, okay?
Exactly.
Can you think of a female caveman name?
I think.
That's what I'm saying.
Wilma?
Wilma?
Wilma.
Does Betty count?
Does Betty?
Betty and Wilma.
I don't know.
That's cheating.
I'm cheating.
So here's what happened.
The reason why I did this for one one of my books a q a book okay
on um merlin's tour of the universe someone had asked when the wheel was invented and it's
we have an idea of when very early but we don't know who right so i wanted to invent
a conversation that would have had between the people who might have invented it. Okay. So I want to be all PC about it.
So I said it was invented by a man and a woman at the same time,
but they're cave people.
So I needed a name for each of them.
So I said, what am I going to name them?
I don't know.
So then I remembered the word troglodyte.
Right.
And I said, and I'd forgotten what it meant.
So I went to the dictionary and it looked up troglodyte and it says cave dweller.
Oh, okay.
That's why that word popped into my head.
Deep down I had some memory.
But there's the dot that separates the syllables of the word in a dictionary.
Okay.
Trog-lo-dyte.
Lo-dyte.
Lo-dyte!
Lo-dyte!
Oh!
Yo, and it sounds like a, it sounds more female, too.
So, I said it was the Trog couple.
I mean, it was the caveman couple, Trog and Lodite.
Trog and Lodite.
Invented the wheel.
Right.
There it was.
You know, Lodite was telling Trog he was doing everything wrong.
You know it.
Lodite, she's like, Trog, you know this is not how we make wheel.
Is that how they spoke?
Right, exactly.
Broken English.
Right, exactly.
Because isn't that how whenever we don't know what people did, it's got to be broken English.
English, broken English.
Just broken, you know.
So, yeah.
And then, yeah.
And then Trog is just like, woman, off my back.
Wow, that's pretty cool.
Lodite.
Yeah.
I like it.
Lodite.
I'm very proud of that.
It's my contribution to literature.
Trog and Lodite, the cave-dwelling couple.
Yeah.
I like it.
You know, that's pretty cool.
All right, Melissa, here we go.
Melissa wants to know this, coming to us from Chino Valley, Arizona.
Hey, Neil.
Finally getting to Melissa's question.
Finally, finally.
Hey, Neil, I'm curious about any thoughts on that i mean from a scientific
standpoint you cannot speak to this because you're speaking about you know the fact of a creator or
some higher power creating this oh Oh, sure you can.
Oh, you can.
Well, so let me be clear.
Okay.
This, if there's a higher power
that did anything in the universe,
there's no reason why that should be beyond
the ability of science to determine that.
Oh, okay.
All right.
Interesting.
So if you do science properly,
you're not precluding any one explanation relative to another if you're on the frontier of discovery.
Right.
Okay.
So I'm not going to say there is no higher power there.
And let me find something else.
If the higher power is there and it manifests, then my methods and tools find it.
I'll be the first one to report it.
Okay.
Okay.
I'll be right there at the front of the press conference.
Okay?
So just to make that clear.
And let's back up.
This is a deep question here.
It is.
We've got more going on than she may even know.
Okay.
Okay?
After Einstein advanced the general theory of relativity in 1916,
it was, oh, my gosh, the universe the universe there's gravity and it shapes the universe in
this way and then in 1929 hubble discovers that the universe is expanding right you take general
relativity and the data that the universe is expanding and a clever physicist named george
lematt lematt okay he was a bel physicist. Looked at that and he said,
wait a minute,
if we're expanding
and I have this new tool,
theoretical tool,
to understand the whole universe,
let's go back in time
and ask,
what would the universe have been
yesterday compared with today?
It would have been smaller.
Right.
Let's go even smaller.
Even smaller.
Take it all the way back.
We go all the way back.
We got to get down to a singular point.
A singular point.
Right.
A beginning of things. Right. get down to a singular point. A singular point. Right. Beginning of things.
Right.
This person is a Belgian priest.
Oh.
An ordained priest.
He must have drank some good beer.
A Belgian beer?
Mm-hmm.
I don't know that there's beer in the church.
I think it's all wine, okay?
It's the body and blood of Jesus, not the body and beer of Jesus. I'm not Catholic. That's right. It was the body and blood of Jesus, not the body and beer of Jesus.
I'm not Catholic.
That's right.
It was the body and beer of Jesus.
That had been hanging out.
Here's to you, Padre.
All right.
Go ahead.
So people immediately said, oh, my gosh, you have found proof of a biblical creation.
Oh, really?
They said this to him.
a biblical creation oh really they said this to him and he a belgian priest came all back in their face and said no what because the bible says the universe was created in six days the bible says
earth was created before the sun there's a lot going on in genesis that is scientifically
untenable right but now you want to take just a little bit that said God created it and say, oh, therefore
it proves the Bible when nothing else that follows it has any anchoring in observational
science.
Right.
He was smart enough to know that this, when I say smart enough, he was sensible enough to know that this should not be invoked as evidence for God creating Genesis as described in the Jewish Bible, in the Old Testament.
Old Testament.
So, because nothing else works there.
Right.
Okay, nothing.
Nothing.
Right.
Okay, earth is in the middle of things.
Everything revolves around the earth.
Earth is flat. So, this goes on and on and on. So he knew enough about the Bible
and about science to not make that connection. Gotcha. So now, so, so by the way, higher power
could be God, or it could be some intelligent alien in its basement programming our universe
for its own entertainment. That would be a higher power.
Wow.
If you think about it.
Yes, that would be a higher power.
Yes.
That guy's really effed up, man.
If that's the guy,
if that, hey, look,
hey, dude,
if you're in your basement right now.
Your parents' basement.
Your parents' basement.
The alien version.
You little pimply face alien bitch, you.
This is effed up what you just did.
Then I
wonder if we are a simulation
programmed by a higher power
maybe they get bored every
now and then and they throw something
to just mess with, throw in
something in the mix. A little glitch in the matrix.
A little glitch in the matrix. A little glitch in the matrix.
Right.
You know, they throw down a disruptive politician or a world war.
Right.
That would explain so much.
Right.
What?
Completely explain it.
Oh, God.
Everything's going along just fine and tranquil,
and they say, you're not entertaining me anymore.
Low date, low date.
Watch this.
Look at what I do right here.
How many times have I told you to stop screwing with those people?
But a broader reference to that question is we don't know what happened before the Big Bang,
and we also don't know what dark matter is nor dark energy.
Right.
If you, and i've said this before
and listen to my words very carefully if you want if your understanding of god right flows through
places where science has yet to tread right because these are frontiers right before the
big bang if that's your concept of god, then the history of this exercise shows us that God would then be an ever-receding pocket of scientific ignorance.
Well, of course.
That only makes sense because you're saying all these other things are provable and knowable.
And so we know.
These other things at one time in the past were mysterious, correct?
They were not. They were mysterious. So now that we know these are provable and knowable and why
they happen, these phenomenon are actually explainable, right?
Like your plural phenomenon. Your plural phenomenon, phenomena, very good.
Do you like that I actually corrected myself there?
Very good. I'm checking you out here. It's cool.
And then you say, well, but what I don't know here, I just think that this is God doing this.
But then our knowledge, our bubble of knowledge expands.
It encompasses that event.
That event is no longer now attributed to God.
That event is also now provable and knowable. And then
that now cannot be talked about. So philosophers call this the God of the gaps. What's it called?
Philosophers call it the God of the gaps. God of the gaps. Right. So in other words,
wherever your understanding fails you, you fill it in with God.
Fill it in with God. Okay. And by the way, this is a long tradition to do so. Isaac Newton did it.
Oh, really? Isaac Newton wrote down his equation of gravity, and it described Earth and the moon, and the
sun and the earth, Jupiter and its moons.
We would later learn it.
So this is all.
But how do you then describe the whole solar system all happening all at once?
Right.
Everything tugging on everybody in all directions at all different.
And he tried to calculate this, and the solar system was unstable,
and planets would fly apart.
Because every time you came around the backstretch,
Mars would tug on you a little bit.
Come around the next time,
Mars would tug on you a little more.
Before you know it, you're out.
You're out.
You're out the door.
We out.
Right.
Okay?
You and the Kuiper belt going,
it's cold.
That's right.
So he would say,
so he said,
well, clearly I know my equations work with a one-on-one situation.
With the whole system, maybe God steps in every now and then just to fix it.
And corrects things.
And corrects things.
He says this in his 17th century lingo.
He says just that.
And so that's basically God of the gaps.
Gotcha.
Ptolemy, who put forth the geocentric universe, this is 2,000 years ago, has a little bit of God of the gaps in him.
He looked up.
People still didn't understand the planets going forward and then retrograde, going back.
And he says, when I trace at my pleasure the windings to and fro of the heavenly bodies, I no longer touch earth with my feet.
I stand in the presence of Zeus himself and take my fill of ambrosia.
Wow.
Yeah.
He did it poetically.
That's a God of the Gap.
He doesn't understand it.
Zeus is-
Zeus is his God.
He's hanging with him right there.
That's how I explain this.
That's how I got it.
Super cool.
See, my God of the Gap
is 40% off
and it's not Labor Day.
Okay?
Thank you, God.
This hoodie is awesome.
Okay.
We got to take a quick break.
We'll be back
to StarTalk Cosmic Queries
in a moment. We're back on StarTalk Cosmic Queries Edition
Specially Topicked
Galactic Gumbo
I love me some gumbo
There's like 20 ingredients in gumbo
If it's done right. I gotta
tell you, Yvonne
Garnier. I
do not say her name in vain,
but Yvonne Garnier, a woman
who grew up in the friends' quarters.
I mean, when you talk about gumbo,
you have never
had gumbo until you have had
Yvonne Garnier's gumbo.
Oh my goodness.
Next time I show, give me the address.
I'll be there.
Let me tell you, man.
Next time you're in Philly, I'm going to have her make you some.
Okay.
No, what we should do is tell her about the Galactic Gumbo show.
Right.
And then have her rename some of the ingredients to be cosmic ingredients.
That would be a special.
Special.
I have to go there and eat it.
Real Galactic.
We negotiate it. There it is. Let me tell you something. I've never. Galactic Gumbo. Never had be a special. Special. I have to go there and eat it. Real galactic. We negotiate it.
There it is.
Let me tell you something.
I've never.
Galactic gumbo.
Never had anything like it.
Never.
Okay.
So I dated Yvonne's daughter for some time.
Oh, now the story comes out.
Okay.
I'm sure she is very happy that I have moved on with my life.
But I will tell you this much from that day to this.
I've never had gumbo like that in my life.
I almost married her daughter just so I could get to that gumbo.
So when did she stop visiting you in prison?
When did that happen?
So galactic gumbo, let's get into it.
Here we go.
This is Kelly Dean from Facebook.
And Kelly says this.
Space has been expanding since the Big Bang.
When we see a galaxy five billion light years away,
would that galaxy not have been closer five billion years ago
and thus taken less light time to reach us in the first place,
signed the Kelly Paradox.
Is that her handle?
That's her handle, the Kelly Paradox.
I like that.
I've always loved the word paradox.
It's a good word.
It's got rhythm and soul.
It almost sounds like what it is.
Exactly.
That's what's cool about it.
Paradox.
That would be onomatopoetic.
That would be onomatopoetic, yes.
Paradox.
Paradox.
Paradox.
You say that and just drift off into ignorance.
Exactly.
Paradox.
Paradox.
Yeah.
Into ignorance.
Exactly.
Paradox. Paradox.
Yeah.
Oh.
So let me recast her question to mean exactly the same thing, but give it a little more
science anchor to it.
Okay.
We see that galaxy five billion light years away.
Mm-hmm.
Where it was when the size of the universe was such that it would take its light 5 billion years to reach us.
Gotcha.
Okay.
Okay, now that makes sense.
Right now.
Because it's still expanding.
Yes.
It has been expanding since the 5 billion years.
There you go.
Therein is the rub.
There's the rub.
That's the rub.
So we're about 14 billion years old.
So 14 minus 5, carry the rub. So over the, so we're about 14 billion years old. So 14 minus five, carry the two.
Nine billion.
You always got to carry the two, right?
In any arithmetic, you carry the two.
So it means the universe has been expanding for nine billion years since it emitted the light to reach us.
Right. So it is much farther away from us now in this instant than it was at the time it sent us that light.
Correct.
So when we speak of, so I and my colleagues, we're a little bit sloppy.
We're precise, but sloppy.
You ask how big is the universe?
I say 13 billion light years across.
Okay.
Well, right at this moment, it's much larger than that.
It's four or five times larger than that
because it's grown since then.
Okay?
Right.
Because we're measuring the light that we see at that time.
At that time.
And so you have to put it in a model,
figure out how much farther it would have gone,
and that gives you the number.
So when I just say it was 13 billion years,
these are observable quantities.
They don't come out of a model
that you would project into the present
for the things that are far away.
But the way I like thinking about it is,
5 billion light years, that's very far away.
Let's get one a little closer, 65 million.
That's like really close.
Very close.
Compared to the, 65 million light years away.
So that galaxy, if they looked at us, what do they see?
So 65 million.
Wait, we're 4.5 billion.
I'm trying that.
What was going on on Earth?
Oh, they're seeing us in our, what's the name of that age?
But they're seeing us getting wiped out.
Yes.
Let me just, instead of trying to be all science-y, I forget the name of the actual age.
But what they're seeing is us getting wiped out.
The wiped outicus.
The wiped outicus, right.
They're looking through their telescope and they're going, oh, damn.
Hey.
Damn, look what just happened.
Look what just happened.
So they're seeing the asteroid hit Earth and render 70% of the world's species extinct.
It's just arriving there now.
Right.
Okay.
Meanwhile, we are 65 million years in the future of that information.
Exactly.
The larger universe in that future.
So it's a fun way to think about it.
If you had super-duper telescopes, you'd see the past of other places. Super cool. Yeah fun way to think about it. If you had super duper telescopes,
see the past of other places. Super cool. Yeah. Oh, well, hey, look at that, Kelly Dean.
Great question, Kelly. The paradox.
The paradox. The paradox.
You know, there's a wine called
Paradox. I did not know that.
Except they spell it differently.
Well.
It's P-A-I-R.
Oh.
O-F.
O-F.
Right.
D-U-C-K-S.
Paradox.
Paradox.
It's like two ducks on the label.
It's very good.
Paradox.
Paradox.
It's pretty cool.
It's a California wine.
All right.
So here we go.
You're not a sponsor of the show, just to be clear. Yes, exactly. We're coming for you, Paradox. All right. So here we go. You're not a sponsor of the show, just to be clear.
Yes, exactly.
We're coming for you, paradox.
All right.
This is Tom Hyde from Facebook.
Tom says, I've always wondered how the universe expanded faster than the speed of light.
Faster than the speed of light.
During the Big Bang, when the universe is full of matter, and matter can't move faster than the speed of light.
Please explain this to me as if I was four because I am four.
No, I put that last part there.
No, no, no, no.
Wait, wait.
If it was, please explain it to me as if I was four because I am four.
Right.
If you're asking that question at age four, then I'm answering it to you as a college.
I will not be giving you a baby talk answer.
That's right.
If you're four years old and asked that.
But he says, please explain it to me as if I was four.
And this is somewhat related to Kelly's last question just a little bit when you talk about the expansion of the universe.
So if you go in the early universe, the expansion rate
was more rapid than it is today.
The expansion rate
for the moment is slowing down,
but it's going to speed up again later
because of the influence
of dark energy.
Mm-hmm.
Dark energy.
Yeah.
But that's a separate phenomenon
going on.
So in the early universe,
you are absolutely right.
We expanded faster than light.
But that does not violate the you can't move faster than light rule.
I know that sounds paradoxical.
It does.
Paradox.
Paradox.
Paradox.
So here's what's going on.
The speed of light limit comes about from Einstein's special theory of relativity,
which describes the movement of objects through the fabric of space and time.
Exactly.
Whereas general relativity describes the stretching of your fabric of space and time, not specifically
things moving through it.
Right.
So the early universe, it is the fabric of the universe that's stretching.
Itself.
Itself.
Itself.
So it's not something traveling through that.
So it's the rubber sheet model.
Correct.
Where you have a, just a sheet.
And all the galaxies are embedded in that
and the sheet is expanding.
And the sheet is moving.
But you are not moving information through space
faster than the speed of light.
But if you're expanding the fabric,
you can expand at unlimited speed relative
to the speed of light.
And so it really is like a rubber band.
If you and I were pulling a rubber band right now, we could pull it slowly.
We could pull it as fast as we want.
Really fast.
It doesn't make a difference.
Right.
But if we have something sitting on that rubber band.
In the rubber band, it's stuck in however it's going to, the ant moving in the rubber band, it's limited.
Exactly.
That's right.
And Chuck, we have a bell.
Lightning round.
Okay.
Lightning round. These. Lightning round.
These are where I answer questions basically with sound bites.
There you go.
I always fail, but let's try.
Who cares?
It's always fun.
See how many we can fit into the last three minutes of the show.
All right.
Ready, go.
Matthew Coles from Facebook wants to know this.
Big Bang causes outward expansion.
Do we know with which direction the origin or center is?
Yes.
We do.
It is in every direction.
Okay, next.
That was great.
Yeah.
No, so it expands in every direction,
and we are part of that expansion.
So you cannot look back to any direction in space
and say that's where the Big Bang happened
any more than you could be on the surface
of an expanding balloon
and point along that surface and say,
there's the center of the expansion.
Right.
Because the center of the expansion is backwards in time at a point where the whole balloon was in that one spot.
Wow.
In the same place at the same time.
Next.
Thomas J. Kastner from Twitter says,
Why do so many people imagine alien life as little green men?
What or who created this strange image of aliens?
Oh, yeah, because little green men with feet and torso and arms and head.
Because you have to pay an actor to wear that costume.
And before CGI, every animate thing was either stop motion capture or had an actor in it.
I think if we were not so limited in the early creativity, especially of the B movie sci-fi
from the 50s, maybe they would have been earlier in the more creative kind of alien.
But that was the joy of seeing the movie Alien, where that creature wasn't so traditional.
It wasn't a little green man.
It wasn't a little green man, nor was the blob in the 1958 Steve McQueen classic, The Blob.
Which, by the way, very inventive.
Very inventive.
It was an invertebrate alien.
Exactly.
What was it?
It was a blob.
Blob.
That was it.
All right, next, go.
All right, Pepsi Rules wants to know this.
How many licks does it take to get to the center of a Tootsie Pop, Neil?
Well, you know, when I was a kid, I tried all these things that the...
I was just geeky enough.
No, wait, wait.
No.
First, how old is this person?
Because this is not even an ad anymore.
You know, how many licks does it take to get...
So I realized that it completely depended on how wet your tongue was.
That's funny.
Because if your tongue were dry, it would take essentially forever.
Right.
So there is no one answer to that question.
And I learned this as like a 12-year-old kid.
Sounds like sugary research.
Not all questions have unique answers.
Some of them have multiple answers, and get over that fact.
Oh, cool.
Yes.
Nice.
It could be thousands.
It could be three.
If you like dog slobber on it.
Okay.
Okay.
We might get two more in this.
Here we go.
This is Tack Neely who wants to know this.
We call the area between planets and solar systems space.
So what should we call the area between universes?
Ooh.
Nice question, Tack.
Great question.
So if empty space is where you find nothing,
we would later learn that it's a seething cauldron of what we call virtual particles.
We learned this from quantum physics.
That's another show.
But let's for the moment call it empty.
Right. Where's another show. But let's for the moment call it empty. Where you find
nothing. Well, if nothing
is where you find the space
between things,
no thing. Nothing.
Get that? That's good.
Can you hang?
Where there
is no thing, there is nothing.
Okay, fine.
But if there's not even nothing,
Right.
then you
are in a higher dimensional place
and our vocabulary cannot really
accommodate that beyond just saying
it is the absence of nothing
where you might then call it nothing, nothing.
So the answer, uh,
tack is Detroit.
What's your time?
You're listening to StarTalk Radio.
Stay tuned.
More up next.
Back on StarTalk. Chuck. Hey, Neil. bringing me the questions that's right this is office hours office
hours so it means it could come from anywhere anywhere anything anything let's jump into
anywhere and anything here's a wolf prime 06 from instagram okay have you noticed people have been
spelling their names phonetically for you and and I appreciate that. I'll take the help wherever I can get it, okay?
I am not proud.
All right.
All right.
Wolf Prime 06 Instagram says,
Cloning exact particles and cells might be the only chance we have at teleportation.
So if we thought it was unethical, then would we stop cloning
and therefore never figure out teleportation?
There's an assumption there that cloning cells is the way to teleport.
Interesting.
Okay, so a couple of things.
As far as we know, every atom of a particular kind is identical to every other atom of a
particular kind.
So you don't actually have to move your atoms to another location.
Just get the recipe.
Right.
Right.
All right.
So grandma's cupcakes, she doesn't, she doesn't make cupcakes for everyone in the universe
to have her cup.
She makes the recipe.
Okay.
Writes down the recipe.
Now you reproduce her cupcakes.
Right.
Okay.
So if i know
exactly how all the atoms of your body are configured and i know what those atoms are
in principle i can reconstruct you what we don't understand yet well enough is the mind and what is
it about your mind that you would have to reconstruct to have the memories that you have
the life that you have that can have your identity identity. Right. Because by the way, in society, we do have clones.
We already have clones.
But we shouldn't have clones.
It'll be ethical.
We have clones already.
They're called twins.
Twins.
Right.
Twins.
Are we taking one twin away and harvesting their organs for the other twin?
No.
We're pretty sensible about things.
Well, that's what I did with my twin.
That's what you were saying.
All right.
I drink a lot.
I know this liver ain't going to-
The liver, the liver.
Liver and kidneys.
Nice two.
Well, because it's a clone of yours, it means it's drinking too.
There you go.
You useless clone.
You useless clone.
So I don't know that the ethics of cloning will ultimately become all that people fear it to be.
Right. I just don't see that based on the knowledge of already having clones today.
There's a danger that if you start cloning pre-existing life, then you will lose the biodiversity that assures the survival of the species.
Wow.
Okay.
So that's a great episode of Star Trek, by the way, where they go to a planet and the
whole planet is made of clones.
What happens though is through the replication, they start to see a degradation over a long
period of time.
And so this degradation-
They're not perfect clones degradation they're not perfect clones
they're not perfect clones anymore and they're like oh my god we're now having clones that
are not what they should be as a result we have to reintroduce good old-fashioned horizontal mambo
to get some dot biodiversity oh and that becomes like the whole issue of horizontal mambo yeah so the people
but that's a thing and that's a new star trek
i think it's an ancient earth term for procreation horizontal mambo
but uh the people are um repulsed by the idea.
Because the cloning is so pure and so high, high level.
Right.
Interesting.
I missed that episode.
It's a pretty cool thing.
It's not from the original Star Trek.
No, I believe this is, I think this is one of the next generation episodes. Next gen.
Yeah.
It's a next gen episode.
Yeah.
So there's the ethics, there's whether it'll happen.
And I think ideally you would just know exactly what the recipe is for
an individual created in another place here's the thing you got to remember twins are identical to
one another but they have different consciences right so one twin is not thinking it is the other
even though all the molecules are identical so except they have different fingerprints because
that happened later in the womb okay but uh But, so that's an interesting fact.
Twins are identical, except for their fingerprints.
Except for their fingerprints.
Right.
So, we're talking about identical twins, of course, not-
Yeah, not fraternal.
Or sororal twins.
Sororal, wow.
That one from Bill Nye.
Okay.
The two ladies in the womb.
Exactly.
Sororal twins. So, we don't understand why I wake up as me Okay. The two ladies in the womb. Exactly.
Sorority twins.
So we don't understand why I wake up as me and you wake up as you every day.
Right.
We just don't understand that.
If we did, maybe we'd be able to clone that.
But then you'd have two of you and you'd have a simultaneous shared conscious.
That'd be kind of interesting.
That would. If you could do that. Yeah. I don't think we need two of me with a simultaneous shared conscious that'd be kind of interesting that would do that yeah i don't think we need two of me with a simultaneous shared consciousness that is for sure that's very cool
then all right let's move on to uh two of me one of me would be like in the lab the other be doing
the dishes and other be seeing the movie i've been missing they emerge the conscious overnight
wouldn't it be cool if you go when you go to sleep all of you would you go to sleep and you all share your experiences experiences it's a syncing program uh that synchronizes up the
consciousnesses now that i could deal with that'd be kind of cool because then you could experience
so much more in life there's a science fiction movie where people share dreams i forgot which
one that was i forgot the name not the uh not inception, that was where you went into the dream.
Yeah, it went deeper and deeper.
Into somebody else's dream.
Right, and that became the reality.
There's one where,
it might've been an episode of a TV series,
but we'll get our crack team of researchers
to dig it up.
There you go.
All right, here's Lammas Pissu, I think.
That cannot possibly be.
I think it's Lammas Pissu.
Lammas Pissup.
Not Pissu. Lammas Pee Soup. Not Pee Soup.
From Instagram says this, very, very succinct question.
Where is all the antimatter?
Wow, what a, that's, hey.
I wish I knew.
Next question.
Actually, there's a friend and colleague of mine, J. Richard Gott III, who wrote a research paper in the 1970s hypothesizing where all the antimatter went.
Interesting.
Yeah.
I did not read that paper.
You missed that?
I missed that paper, oddly enough.
Oh, my God.
And what was his hypothesis? He suggested that at the point that we had this asymmetry between matter and antimatter in our early universe, that and created another universe with an antimatter matter imbalance.
That's the inverse of our matter antimatter imbalance.
Oh man.
It's beautiful.
Right.
It's a really beautiful thing.
It's very elegant.
It's elegant.
He thinks up elegant things,
whether or not they're true.
Right.
Elegant.
Yeah.
And the universe just,
there's a great comment.
I think it was by, was it Aldous Huxley or one of the physicists?
It was the great tragedy of science, a beautiful theory slain by an ugly fact.
I love that.
So it's a elegant concept that there's still balance in the metaverse right and because this
imbalance is kind of just it's disturbing yeah yeah in the greater scheme of things so but there's
no evidence for this other universe okay all right yeah all right j lauren 74 from instagram
says this i believe in an earlier episode, Neil said that the shape of the universe
is a saddle shape. Is that right? If not, please, what shape is it? I can't imagine it not being
a sphere. Yeah. So we're flat. If I said saddle, so there are different shapes it can be,
can still be consistent with Einstein's equations.
And so one of them is sort of spherical.
Another is sort of flat and one is saddle shape.
So one is positively curved.
One is zero curvature.
One is negative curvature.
And so if you add up the dark energy and the dark matter and the matter and the energy, add it all up, the universe is flat.
Wow.
Yeah.
So there you have it.
Yeah, yeah, yeah.
So it's interesting.
So if one of them had a greater value than the other, then we would have one of these other shapes.
And what's the difference in a spherical universe?
Parallel lines always meet.
Hmm.
In a flat universe, which is, we learned about flatness in geometry class,
parallel lines, you know, they, they, well, they meet at infinity.
I think it was the phrase, but basically they never meet.
Never meet.
Right.
And, uh, in, in a negatively curved universe, parallel lines diverge.
Right.
So these are three completely legitimate geometries.
And so Euclid was a flat universe.
And the others that are not Euclid, you know what we call that?
No.
Non-Euclidean geometry.
Oh.
I hate calling something in reference to what it's not.
Yeah.
That's a little disappointing.
Right.
You know what I mean?
I wanted Freddy's universes.
Freddy came up with it.
Right.
No, but I don't like unretouched.
Unretouched.
Yeah.
That meant you didn't do anything to it.
I don't do that.
You shouldn't have to have a word.
You shouldn't have a word.
Yeah.
It's just what it is.
Non-fiction.
I want to invent a new one.
I'll call it faction. I like. Well, do that would do that i would send out a tweet faction is that right non-fiction right i don't
want my stuff referencing what isn't somebody what somebody else did right no i ain't doing
that i don't play that sweet okay uh i think we have time for one more question. Okay, one more. And this is SEBSP at Instagram.
Says this, could the gas giants still be forming planets or a planet in formation?
I think that's what they mean.
I think you're right.
Because otherwise it doesn't make any sense because Jupiter is a gas giant.
It is a gas giant and it's not a star.
Right.
So I guess they mean a planet in formation.
So Jupiter radiates more energy than it receives from the sun.
Oh.
So you want to call it a star?
It gives off more energy than it receives from the universe.
Yeah.
But generally we define stars as having a source of thermonuclear fusion in their core.
Okay.
You can emit energy if you're slowly collapsing.
That you get hotter if you do that, if you're just slowly collapsing.
Or if heavier things are dropping to the center as lighter things rise to the surface.
These phenomenon, it turns out, you will heat from this.
Right.
It turns out will heat will you will heat from this right turns out
but gas clouds that make gaseous planets you know out of the starting box whether they're
going to be stars this is not something that happened gee i was that's it right i want to
be a boy one day i don't need my strings attached right No, the mass is either going to take you there or it is not.
Gotcha.
And there is the Netherland, which is the, what we call brown dwarfs, which are
transitional, we say transitional, but we don't mean it in the way you might think.
You have massive planets like Jupiter, you have low mass stars, and you have this thing
in the middle that we call brown dwarfs.
Right.
They're not transitional in that they're not evolving from one to another.
Right.
They just occupy this middle zone.
Gotcha.
Between what a planet is and what a star is.
And they're failed stars.
Stars.
We're super, they're overachieving planets, failed stars, whatever you want to call them.
But we have a term for them, they're called brown dwarfs.
Brown dwarfs.
Yeah.
Sweet.
All right.
You got it. Chuck, thanks for doing this always a pleasure always there i'm a listener
you're always there for me where else do i have to be well you don't get gigs i just do them on
the side on the side okay we are your main squeeze yeah that's it you know what i mean i got my little
side pieces all right i mean but every time they come I'm like, now you know who my woman is.
My woman is StarTalk.
This has been StarTalk.
You've been listening or watching Cosmic Queries Office Hours Edition.
And as always, I bid you to keep looking up.
