Can't wait for the next one! I have to admit that I didn't really understand half of what was said, probably because I don't have a science background. I'm not sure if I am listening above my education, or these are just really hard concepts to wrap your mind around? I have a lot more questions than answers, but that's not a bad thing, lol. For example, what did Katie mean that the things are not expanding, but the spaces between them are? If we and our world are expanding, how would we know that 9 inches was now a longer length, but we still only see it as 9 inches because the ruler expanded too? Or would the ruler stay the same and spaces between between two objects expand? So everything in the universe stays same, but becomes further apart? Or do the spaces between molecules expand, and how would we perceive that? Is this happening on a galactic scale, and too tiny for us to observe? My brain has a hundred more of these questions, so I hope future episodes will clarify a few things. Sometimes I feel like us studying the universe is akin to microbes trying to fully understand the petri dish they live in. 😂

It'd be funny if they changed John's label for every clip. Like "Katie Mack, astrophysicist", "John Green, not that"; "John Green, hopelessly unqualified"; "John Green, self-described enthusiast"; "John Green, just here for the company"; etc.
@@NotaWalrus1 Yeah, it seems like the idea is that _there isn't an edge_ we have evidence of, so "smaller" and "bigger" don't mean anything. But "denser" and "sparser" do.
*observable universe* the part that we can theoretically get information about, and that part (just like the other parts) used to be a regular dot-like small tiny tiny region, full of suuuper hot quark-gluon plasma (like the rest, due to the isomorphic principle) based on the curvature measurements we know there's a lower limit on the size of the universe (not just the observable part), but usually it's assumed to be infinite
My headcanon is that the initial animation of John's star flipping behind Mack's star at 0:21 is symbolic of his intense existential fear of the Big Bang Theory that appears on screen, protected by Mack's knowledge and expertise. Then after she explains it, at 0:51 he's brave enough to stay near it, having gained knowledge and through that knowledge, confidence and fearlessness. Love the podcast and these animations!
@@kashiichan Yes! This! I was worried I wouldn’t be able to follow without video of them because my auditory processing is so bad but the little stars helped so much. I would’ve never thought a graphic lighting up when each person is speaking would actually make a difference in my auditory processing so this is revolutionary to me right now.
sure. Sure. The name is also a pun on the fact that the main character wants to have sex with the hot neighbor from basically episode one, minute one. So science consultants. And also 13yo teenagers from 1992.
I listened to it! It’s about to be my favorite podcast, I’m a space nerd and John Green is participating, two of my favorite things! Good job to Katie for the great lecture.
I really like this format. I struggle with 99% of podcasts because I'm such a visual person. I realize this takes longer to produce, but it's so helpful to have something to look at and absorb. Thank you.
The soup is a state of equilibrium, so everything is soup by default, and everything that's not soup is random noise. From the soup we rise, and to the soup we shall return.
@@ericmichelsen3931 I'm also frustrated by it! I also just wonder if there's some stuff we won't ever be able to know. Like (genuine ponder - ) by what means could we ever determine how everything got there, or what was there before anything
I *loved* the first episode, John. Definitely feels like the spiritual successor to TAR. Thank you to you and the team for bringing Katie and her communication to a new audience.
I just had a mind blowing thought about all of this. The fact that we're in a cooling universe, that eventually all life in the universe will be extinguished and grow cold does indicate the most fundamental of science which is newton's law: of objects in motion staying in motion unless being acted upon by an outside source. The entropy of the universe signifies finite resources, suggests possible outside interference from outside acting sources, and maybe even a slowing down of the pace of the universe to me, even if it's infinitesimal.
I love this and would love to see more in this style of content. One note is during the very dark space sections, the rotating textures are way too visible and really distract me from paying attention to what I should be looking at. I'd really love if it were just about half as transparent as it is now. /end art director rant 😅 - Love, a former PBS Spacetime Motion GFX Artist
I've listened to the first episode of this podcast eight times already. I am a re-listener/re-reader/re-watcher of content, but that's a lot, even for me. Lol but yeah it's really good.
So do we even know that the hot and dense state of the universe before was “the beginning”? Could there be more before that? How dense was the universe exactly and how do we know it wasn’t a singular point?
Now they need to figure out what happened before the "beginning", and whether the big bang happened in the entire cosmos, or whether it was just a sort of local event.
The space everywhere is expanding, but it can't overcome even very weak distant gravity currently, let alone the strong/weak nuclear forces. The distance between atoms is not getting greater, just like the distance to the sun is not changing. Expansion is only seen on the most massive of scales currently.
I loved this explanation on the podcast! It left me with a question: when the radiation that we see now as the cosmic microwave background was emitted, how far apart was the matter that emitted it at that time? Orders of magnitude approximations welcome, if my question makes sense!
You and Hank should really play Outer Wilds by Mobius Digital. Maybe the best creation yet at helping people understand difficult concepts about the universe from inception to death by using music, art, emotion, and mystery to pull your curiosity in the right directions. Knowing the universe isn't about having the answers. It's about asking the right questions.
The animation starting at 1:52 is confusing at best. If the animation is to believed, objects far away appear red and close by appear blue. While in fact the moving away and moving towards us is what makes them appear red or blue (which is precisely _not_ shown in the animation)
I'm just happy to have more cosmology. It's 2024, which is slightly further in the future than 2020, so I look forward to hearing slightly more up to date info on certain bits ;)
I love space. The existentialism of it and the science of it. But i hate physics, so clulf never really pursue anything related. I dont think overthinking the idea the universe while not knowing the science of it is a unique condition. So i am very thankful one of us aka John actually has a platform and decided to use it to quench our curiosities.
But doesn't that mean that the observable galaxies/light that's moving away from us... wouldn't it also be moving away from other places too, thus some things moving toward us?
Who would have thought a nerd rock band would have understood what the Big Bang Theory was, back when most people thought (and still do) that it was a literal explosion?
Aand the lady dr didn't answer main question - how the universe looked like before the big bang - how big was it? We know that some elements can change their density up to some point - like water - it can be pressured a lot and it doesn't change its volume much - so again - how big was the universe before it began - I know - my question seems to be stupid, but if everything was created from singularity soe it seems like it was created from nothing. But from the other hand there was something - a singularity.

We should get an episode where John explains everything about TB to Katie and Katie is as clueless as John was in this episode.
+
Pleeeaaase ✨
This would be a great bonus episode at the end of the series! "And now, some current happenings in astrophysical times"
It may have been the leading cause of human death for millennia, but that's like yesterday compared to the universe.
++
“Katie Mack, astrophysicist” “John Green, very curious” loooool that’s so funny and relatable 😂
It'd be funny if they changed John's label for every clip. Like "Katie Mack, astrophysicist", "John Green, not that"; "John Green, hopelessly unqualified"; "John Green, self-described enthusiast"; "John Green, just here for the company"; etc.
so the idea isn't "the universe used to be tiny", it's more "the universe used to be a lot smaller than it is now"
Denser, not really smaller. The universe was likely the same infinite size, just that everything in it used to be a lot closer together
@@NotaWalrus1 Well, infinities confusingly come in different sizes
@@NotaWalrus1 Yeah, it seems like the idea is that _there isn't an edge_ we have evidence of, so "smaller" and "bigger" don't mean anything. But "denser" and "sparser" do.
*observable universe* the part that we can theoretically get information about, and that part (just like the other parts) used to be a regular dot-like small tiny tiny region, full of suuuper hot quark-gluon plasma (like the rest, due to the isomorphic principle)
based on the curvature measurements we know there's a lower limit on the size of the universe (not just the observable part), but usually it's assumed to be infinite
@@NotaWalrus1 Or it was still infinite, just a smaller infinity?

This is such a nice podcast, especially the visuals with their respective stars lighting up every-time they speak.
I love it so much. I have auditory processing issues and it REALLY helps
Reminds me of Its A Wonderful Life with the Angels talking lol
@@kashiichan
Yes! This!
I was worried I wouldn’t be able to follow without video of them because my auditory processing is so bad but the little stars helped so much. I would’ve never thought a graphic lighting up when each person is speaking would actually make a difference in my auditory processing so this is revolutionary to me right now.
I find it hilarious that an actual astrophysicist explains the Big Bang theory with the TV show theme song, The Big Bang Theory.
I have a lot of problems with the Big Bang Theory tv show, but they had science and mathematics consultants and it shows.
Just waiting for a paper to cite "Barenaked Ladies et al (2009)"
sure. Sure. The name is also a pun on the fact that the main character wants to have sex with the hot neighbor from basically episode one, minute one.
So science consultants. And also 13yo teenagers from 1992.
The worst part of this clip was when Dr. Mack said "back in the 20s ... Er, the 1920s". I felt that right in my lower back.
I listened to it! It’s about to be my favorite podcast, I’m a space nerd and John Green is participating, two of my favorite things! Good job to Katie for the great lecture.
Same!
LMAO Im here for the "It's a Wonderful Life" Star animation 😂
Yeah, they really moved on from helping George Bailey.
I was trying so hard to remember what movie this effect was from!
+
John shows proper enthusiasm for not knowingness. It's the perfect place to understand science.
The stars glowing and speaking is just like the beginning of It's a Wonderful Life, in the best way.
Katie Mack is an awesome science communicator! I am excited for this series.
I really like this format. I struggle with 99% of podcasts because I'm such a visual person. I realize this takes longer to produce, but it's so helpful to have something to look at and absorb. Thank you.
extra Saturday video! that's like finding $5 in your couch... what a pleasant surprise!
Happy Saturday, universe!
As Mack explained, there will be darkness again
I listened to her audiobook and gasped so many times.
So it was hot and dense, but we don’t know what happened before it was hot and dense!!!??? What happened before the soup! Who made the soup!
This isn’t made to be religious, just frustrated we don’t have a presoup answer
The soup is a state of equilibrium, so everything is soup by default, and everything that's not soup is random noise. From the soup we rise, and to the soup we shall return.
@@ericmichelsen3931 I'm also frustrated by it! I also just wonder if there's some stuff we won't ever be able to know. Like (genuine ponder - ) by what means could we ever determine how everything got there, or what was there before anything
"Good morning Hank, it's the beginning of the universe."
A visual doppler effect to describe the expansion of the universe 🤯
Katie is fantastic, great to hear her!
In the first minute I learned that I've thinking about the BB wrong. Incredible. I'll definitely check this podcast.
So looking forward to this.
This is the earliest I've ever been here but I gotta wait and watch in a moment. I'm so hyped for this tho ❤❤
This is content I would like to continue watching. Maybe a series.
I listend to the episode already and it was great! Can't wait for the next one!
I just started this video and it’s giving, the angels discuss George Bailey in the beginning of It’s A Wonderful Life
Omg this is beautiful and I'm so psyched to hear more!!
"Since the 20's"
"... the 1920's"
I am enjoying this format.
Tuna, I love the music SO MUCH!
Really liked the animation on this one
I found this conversation relaxing. I don't know why. Maybe it's their voices?
I *loved* the first episode, John. Definitely feels like the spiritual successor to TAR. Thank you to you and the team for bringing Katie and her communication to a new audience.

Amazing how learning about cosmology can be so grounding for your consciousness
Henry Reich called it "the everywhere stretch" once.
This was a great podcast and can't wait for the next episode
This looks so good and fascinating - thanks for my next pod to put on my queue ❤
As Mack explained, there will be darkness again :))
I loved ep 1!!
I've listened to the first episode of this podcast eight times already. I am a re-listener/re-reader/re-watcher of content, but that's a lot, even for me. Lol but yeah it's really good.
Great video! Also, I love the homage to "It's a Wonderful Life"!
Oh I'm going to love it! Perfect timing, I'm just getting into this stuff 🤩
So do we even know that the hot and dense state of the universe before was “the beginning”? Could there be more before that? How dense was the universe exactly and how do we know it wasn’t a singular point?
Been watching since 2009, first time first?
Everything All At Once.
Who made these gorgeous animations??
blinking stars remind me of its a wonderful life and i love it
Interesting and facinating as heck ❤Luv ittt ❤️
Very nice
Now they need to figure out what happened before the "beginning", and whether the big bang happened in the entire cosmos, or whether it was just a sort of local event.
Katie Mack is such a legend.. ❤
"shut up." - John Green
Epic moment.
John Green and cosmology?? never expected to see this pairing
I'm not used to John's voice being this crisp
No I only need Mack to explain how there's no hand on the reins and that there will be darkness again
Surprise Saturday video... well I am here for it.👍
This looks like what i imagine the thread looks like
Great video.
I really thought this was going to be Katie Mack explaining the storyline of the Big Bang Theory tv show lol
She is. She's just going really deep into the backstory.
2:11 Err... aren't they kind of? The space between particles is expanding too, just not at a significant rate... yet.
The space everywhere is expanding, but it can't overcome even very weak distant gravity currently, let alone the strong/weak nuclear forces. The distance between atoms is not getting greater, just like the distance to the sun is not changing. Expansion is only seen on the most massive of scales currently.
loved the end of everything. best book on the end of the world since the end of everything forever.
I loved this explanation on the podcast! It left me with a question: when the radiation that we see now as the cosmic microwave background was emitted, how far apart was the matter that emitted it at that time? Orders of magnitude approximations welcome, if my question makes sense!
Hi Hank! Hi Dr. Mack!
You and Hank should really play Outer Wilds by Mobius Digital. Maybe the best creation yet at helping people understand difficult concepts about the universe from inception to death by using music, art, emotion, and mystery to pull your curiosity in the right directions.
Knowing the universe isn't about having the answers. It's about asking the right questions.
Off topic but just John's voice by itself kept making me think it was Levni Yilmaz (Tales of Mere Existence)
The animation starting at 1:52 is confusing at best. If the animation is to believed, objects far away appear red and close by appear blue. While in fact the moving away and moving towards us is what makes them appear red or blue (which is precisely _not_ shown in the animation)

So i am very thankful one of us aka John actually has a platform and decided to use it to quench our curiosities.
Wow. I just finished listening to THIS EXACT PODCAST, only in Danish, and John is a comedian called Christian...
It would be more logical to think of the Big Bang as the beginning of our time line within an infinite Universe!
what if our universe is essentially a supernova on a scale we can't even imagine
In the beginning, there was soup
But doesn't that mean that the observable galaxies/light that's moving away from us... wouldn't it also be moving away from other places too, thus some things moving toward us?
i like the "it's a wonderful life" influence where katie mack is god
Hooold on radio waves are light waves??! Not sound waves 🤯
Oh yes I don't know what this is but I love it
I thought she was going to explain the edge.
Bazinga!
EXCELLENT NEWS
NO EDGE!!

Thanks for the easy to digest bite of science. 🍝
Nice
The Horrendous Space Kablooie!
Thats funny... my wife says that im "hot & dense" at least daily.
Here at 49 comments and 2959 views, which is wild. Never been this early before.
I like how much bigger Katie's star is.
Ms Mack seems to use astrophysicist and astronomer interchangeably. But there are astrophysicists who gets worked up about being called an astronomer.
It's just a theory
But is there an edge? I would like a professional explanation of NO EDGEEEE
Calling the song The Big Bang Theory theme song is Bare Naked Ladies erasure
🔥🔥🔥🔥
I like my men like I like the universe before the Big Bang. Hot and dense.
