Did you get your mind-blown during this episode!?

I love how Chuck, over the years, seems to be understanding more physics.

We see Neil and Chuck: we Click. We see Janna : We Grab the Popcorn.

Constructive criticism from South Africa: Hey Neil, I'm a big fan of your show and appreciate how much you share your knowledge. One thing I've noticed is that sometimes you cut your guests off mid-sentence. While I know you're enthusiastic to share your thoughts, it can be frustrating for listeners who want to hear the full point the guest is trying to make. I've learned so much from you and your guests, and I think letting them complete their ideas would make the show even better. Just a suggestion! Keep up the great work.❤

I would describe Janna's outlook as "I live the life I love and I love the life I live." How frickin' wonderful!

Janna is my #1 favorite guest of all time. She is such a wonderful science communicator and person. I love her chemistry with Neil and Lord Nice

It's always great when Janna Levin is on the show. Brilliant Episode!

I used to vehemently hate Neil because i thought he was arrogant, and a know it all, and obnoxious. This was difficult due to my love of cosmology and science at large. He would come up in numerous videos I watched and he just sort of became a necessary evil in my search for understanding of the universe. But the more he came up, and the more I listened, and heard not just what he said, but also how he said it, and who he is and what his mission is as a human, I can now say I genuinely adore the man. I say this because as I was listening to his monologue at the end and I was staring into his eyes, I realized how much I love and respect him as a scientist and a fellow human, and was struck with this weird feeling that I somehow used to despise the man. Listening to a persons words and learning their heart can change yours. If there is someone you hate today... maybe give them another chance, maybe 10 or 20 or 100 more chances, like I did, and you may very well realize your hate is simply misunderstanding, or your own ignorance. Thanks Neil for making the Human Race a group I'm proud to be a part of.

The existance of only one electron in the universe that simply runs back anf forth through time can explain a lot. 1) why they the same 2) problems of large numbers: in a universe with a mass of 10^56g approximatly 10^80 electrons and the ratio of the visible universe size to the electrone size exatly 10^40. That is just one layer to go back in time 3) the experiment with two slits is easily explained 4) positrons just electrons moving back in time 5) collision of electron and positron destruction of the loop. Therefore , there are so few of them for the whole structure to work.

If I can go back to my teen years with the knowledge that I have now, I would become an astrophysicist. Ever since I was a kid, I always looked to the skies knowing that one day I will see something extraordinary. Thank god for podcasts. We definitely appreciate you and chuck. Keep feeding us knowledge.

I need another live Startalk with Janna Levin!

This was by far my favourite StarTalk! So many revelations in my own head. Thank you.

You need to have a 2 hour show for these 2. I love it when she’s on. I hope you have her on again soon.

It took me a year to understand the title of Janna's book " A Madman Dreams of Turing Machines " . Janna is a gift , so grateful for all of her remarkable work. ❤from🇨🇦

It’s amazing how studied/knowledgeable/intelligent these people are. I wish I had the mind needed to be this smart.

Been waiting for these in person talks ❤❤❤

Janna Levin is an absolute fave! I've been following her for years and she never fails to say something that blows my mind.

Chuck I got you covered. Had to rewatch with some slight "elevation" and oh my. Janna and some of the things Charles Liu pops off with completely blow my mind. I love it.

How can you fit that much information that can be immediately accessed into one human brain and still not only have enough room left for common sense...but a great sense of humor to top it off...and wrapped up in a beautiful package...

so good to see you all together in the studio!!

Great, guess I'm staying awake for another hour then!

The last minute or so of the video is what we're all here for and what made Startalk what it is today. Neil, when u talk like that it puts me in a trance. Please give us more of you and your way of communicating in future episodes. I miss when YOU were the focus. Im not trying to discredit anyother person associated with Startalk. But your the true 🌟

Not blown away yet still digesting what was said and forming new questions in a bit of a different direction. Changing the way you investigate relativity with different data input. This way of looking at old formula I think I am able to understand better how a friends discussion on how the bending of light could be the source of gravity without gravitons. And the realization that my friends have a warped way of thinking, but now I see better how they are thinking thanks to Janna Levin and to Star Talk for opening a new door in my way of understanding reality and my warped friends.

This episode was wonderful! So confused, but amazing to know how complicated and yet very simple everything is.

Awesome podcast!!! Please have her a regular! So interesting and inspiring to be able to explain such complex concepts in such beautiful and engaging and understandable ways! Ten out of ten!!!

These are always so good! After a long day just to think about how big the universe is and question our own existence. I thank you for taking the time to discuss these topics.

Janna is the first guess I can relate too. The Quantum world makes me question the nature of reality too.

Neil and Chuck for 2024!

I love conversations like this. Things that make you have to think about it deeper. Things that make you go huh that make you question your own thinking. Keeping an open mind to learning and also thinking about the possibilities of all things .

Neal, Janna, Chuck. The one electron theorem was explained in Dion Fortune's 1942 book, "The Cosmic Doctrine". Ring Cosmos (the attraction to the center and the inertia of remaining still), Ring Chaos (the attraction to the circumference and the inertia of remaining in motion - which left unchecked would continue on to oblivion). The Ring-Pass-Not becomes the balance point that holds everything within the toric field). And that is the point of manifestation. (That is what string theory shows.) The initial movement between Spirit and matter, once set in motion will continue around indefinitely. So yes, until the Oroboros is filled to satiation it is as a plane of existence. Once filled or satiated the Oroborus opens up to exhibit itself as a spiral and then there is a splitting off akin as to one cell becomes two. The inversion points are akin to the Guardian of the Above and the Guardian of the below, both of which are our reflections mirroring back to each of us our level of consciousness. It's one electron and it ALL OF US. See, so WE ARE ALL ONE!

Chuck is in another dimension😂

#Question In the TV Series Star Trek Voyager The Borg open a “Trans-Dimensional Rift” which opened a “Gateway” to Species 8472 and when Voyager goes through that Rift they end up in “Fluidic Space” when Space isn’t really Space, it is Matter. So think of Space as we know it Only it isn’t “Space” it is filled with Matter (Think of moving through water like a Submarine) the Submarine is the spaceship and the water is Space. (Keeping in mind the “Multiverse” would something like that possible AND how would Physics work in that Realm?

I gathered a small part of this so far, what I did gather will not be retained and I love it.

I’ve been watching Startalk since the nat geo days and Janna Levin is easily one of the best guests you have on. I like when guests and the hosts can all be in one room. Face to face interaction is better than webcam interactions, though webcams are convenient and allow guests at a distance to be on that might otherwise not be.

I love the chord analogy - a chord is more than the assembly of individual notes, because of the overtones between those notes.

She does an absolutely phenomenal job of explaining complex ideas. And even more impressive, she manages to stay coherent and focused through the constant (I mean CONSTANT) interruptions and peripheral inputs Neil offers. I would have loved to hear her complete her thoughts/arguments to completion. I bet she would’ve have developed them even more impressively.

Nice Episode. I believe so much of our human understanding is limited within perception, translation, communication. We I try to conceptualize my understanding of things I end up questioning so much. I love listening and watching episodes to hear thoughts on things that I can trust have data behind them. I might question the translation of some data but I don't have the resources to look into most of what I question so hearing scientists who are still curious is refreshing.

I don't know who else noticed this thing but Mr.Chuck seems to have been benedicted with a special talent of picking the exact last words from the sentences coming out of Mr.Tyson's mouth. I enjoy it every time with a pinch of awe in my mind. 😄🫰

It’s interesting how Neil and Janna explain the unfolding of “the big picture” in changes with scientific theory. I wonder if the assumption that “science is ‘about’ overthrowing the old theory” comes as a consequence of political thinking.

your measuring is the partical in universe. so wouldn't it not care if its in milky way or Andromeda it scans the reality to see if it is still exists or not. the question is can you send it and it not pop up? that would mean it left the universe which is the first steps to traveling to the multiverse.

DEBATE TERRANCE HOWARD!!!!!

Chuck needs an honorary grad degree with how much he has sponged up over the years. Fabulous to see someone who used to think on a more juvenile level to relate and comprehend on a more upper scale level! Props to him for being so curious and taking the show serious enough that it benefited him! Keep it going chuck! I remember forever ago you used to joke about StarTalk forever being on the air.......BUT maybe the torch can be passed to you in due time.

Chuck impresses me listening all these years..bravo. this has to be one of my favourite episodes..

Neil let her talk stop interrupting oh my god

General relativity and quantum mechanics will never be combined until we realize that they take place at different moments in time. Because causality has a speed limit(c) every point in space where you observe it from will be the closest to the present moment. When we look out into the universe, we see the past which is made of particles (GR). When we try to look at smaller and smaller sizes and distances, we are actually looking closer and closer to the present moment (QM). The wave property of particles appears when we start looking into the future of that particle. It is a probability wave because the future is probabilistic. Wave function collapse happens when we bring a particle into the present/past. GR is making measurements in the predictable past. QM is trying to make measurements of the probabilistic future

Janna is the BEST guest. I wish she could be a regular. She is so immensely intelligent and yet answers questions and makes them so easy to grasp.

Thank you , I very much enjoy discussions on these topics.

The content has been top tier

Love when Dr Levin is on! The best guest!

I've watched dozens. This is one of my favorites.

these talks with janna levin are legendary. absolutely amazing!

Talking about notes and cords… the first thing that popped it to my head was A-minoooooooooooooor 😭

Neil; So....Neutron walks into a bar. Sits down, orders a drink. The bartender brings him his drink and says, "For you, no charge."

Loved this episode of your show.

The most fundamental thing I've seen from this clip is the incredible accurate impression Chuck does of Neil "You know there's no such thing as gravity now"😅

You should accept an interview and debate Terrence Howard

Tyson and Terrance. Make it happen!

Gotta get up in 3h for work, worth it

Love this show. So calming and informative

I've re-listened to previous episodes and the scientific growth of Chuck is interesting to see. Then thought it most likely mirrors mine!

Ohh im SOOOO rrady for thia video! I love jana levin!!🎉

Janna and Neil two of my favorite scientists. Thank you for this podcast.

Dung beetles use the Milky Way to navigate their poo balls in a straight line at night if i remember correctly. 🌙💩 🌟 So they do look up. Great episode!

Worse things in life than getting closer to Janna...

Yeah, we need more of Janna! My favorite guest on this show.

These discussions always trigger a memory of watching 'Horton Hears a Who'....I mean that in a good way! And I adore the Einstein and driver story. Thanks for posting :)

"If...maybe...could...might...what if...possibly...perhaps..."

Janna, marry me and teach me about the universe

It is very pleasant and interesting to listen to you science-nerds talking about the forbidden large and small. Thank you for sharing.

Startalk gives me a deep sense of regret. When I was a kid in high school I loved physics and math, but I loved physics and math. I struggled so hard to find a path forward for my life and being the mid 80’s we didn’t have the internet, so access to people like you all just wasn’t there. If I was in high school right now, I would absolutely want to follow in Neil’s footsteps. I’m sad that I didn’t have someone to push me that way.

For the longest time I thought her name was Jan Eleven ha

Neil is the very definition of someone who literally loves the sound of his own voice, which I suppose we all do to varying degrees. I just wish he'd learn to allow his guests to speak occasionally.

In the discussion about rotating euclidian space via a lorentz boost, something in the description right after felt off. You can't actually orientate something within 3-dimensional space without utilizing the lorentz boost (time), or treating it as a portion of a four-dimensional euclidian object being observed in 3-dimensional space, which can be oriented in a separate way from it's other fourth-dimensional counterpart in any 3-dimensionally observable way without breaking 4-th dimensional consistency; but you cannot re-orient something within 3-dimensional euclidian space not utilizing another form of dimensionality without breaking the euclidian space to do so. That is to say, 3-dimensional orientation is static; as are any observations within it. It would be like taking a holographic photo of a room, and never being able to reorient the things in the room without altering the photo or utilizing time in order to accomplish 'change'. Whether that be change in observable perspective, or change in the observed space (eg, people growing physically older as time passes). 'Change' of 3-dimensional space is thus possible only in a fourth dimensional sense, either reconfiguring the observable orientation of 4-dimensional euclidian matter, or considering the natural 'change' of said orientation as 'time'- 4-th dimensional movement observable in our 3-dimensional euclidian capacity. It's much like the common misconception people have of light being the speed of time- that's not accurate: as a thought experiment, let's say there are three stars, stars A, B, and C. Stars A and C are moving directly away from each other at just over half the speed of light, while star B hangs out directly in the middle. Let's say each has a planet with a civilization eventually capable of light-based communication with each other. Light from star A and C will never reach one another; their combined movement would be too fast for light. However, both A and C can communicate with star B. Let's say that star A communicates a message to star B at (for simplicity's sake) one light-year of distance from star B. It reaches star B one light-year later, and they then communicate that same message to star C when they receive it. Star C is already a light-year away, but moving at just over half the speed of light, they'll receive the message from star B that was sent from star A approximately 1.5x more the amount of time it took star A's message to reach star B. Ala, not infinite time. Likewise, light not being a barrier for information exchange. This separates light from having anything to do with 'being' time, it simply measures it in a scale, as Farenheit or Celcius measure temperature. Time exists regardless of light's interaction with it, but our own ability to observe distance- space, is limited by our observation of light through time. On another matter, touching on the question regarding the stretchiness of spacetime being finite; in classical theory, if spacetime is not infinitely stretchy, black holes should be 'eating' vast quantities of spacetime far more than what we consider 'matter'. Thus, white holes should expel far more spacetime than matter, and should realistically be observable as cosmic voids. Yes? By some theories, inside a black hole would be a vastness of space compressing possibly leading to a white hole; if this is the case... if a large black hole eats a smaller black hole, if matter and spacetime is swallowed by the blackhole in a causal sense (one thing getting 'eaten' before another), in theory if a swallowed black hole by a black hole means a white hole expelled from a white hole, the distribution of both matter and spacetime/void into a blank canvass lattice would not be even, as say, a black hole that has become a white hole which gotten 'eaten' before another different black hole would come out as a white hole expelling its own 'eaten' spacetime and matter causally before the other 'eaten' blackhole turned whitehole comes out and begins expelling its own 'eaten' contents of spacetime and matter. Ala dark energy, and uneven matter ...what's the term here...? 'Creation'? 'Observability'? Matter's 'coming into existence' within our observability of the universe. I realize this is long; I felt it worthwhile to share these thoughts.

When I was 12-13 I thought the universe could be “printed” by a single particle not bound by time. Omnipresent. It made everything, and moved everything, because it was the only particle. Imagine a higher dimension etch a sketch running in “real”/“our observable”time. Can’t wait to watch this!

Terrence Howard said he wants a debate with Neil

She mispronounces Schrödinger in multiple ways. Does this mean that elsewhere in the multiverse she pronounces it correctly?

Very enjoyable podcast. I listen during my night shift at the grocery store.

I think superposition describes the wave function which won't apply to the particle. In transit energy takes wave form and when it contacts a surface that can absorb the energy it reaches it's destination as a particle. What we know as particles are like the holes left behind when a rifleman shoots a target, but to make the analogy work the bullet would be pure energy and travel as a wave. Waves also can't be seen by us because of the fundamental properties of waves and our sense of sight. Our sight works because waves of light are reflected off a surface and hit our eyes which take those particles and with the help of our brains were able to get an image of whatever light enters our eyes. On a side note I think it's incredibly fascinating how light can relatively accurately portray everything around us. The pure mechanism of light bouncing of a surface and then interacting with our eyes to form shapes, colors, depth, and everything else, it's hard not to be humble.

If I had to drink every time these two interrupted her while she was speaking with their feeble attempts at humor, I'd be dead. She's obviously the smartest person in the room, but the egos or the manners (or both) on the other two are so out of line that they just can't shut up and let her finish a complete thought.

I can't be the only one who felt that during this episode Chuck is leaning more towards science-y takes and Niel is doing more comedic takes. Its amazing, these two have worked together for so long, they have basically come to learn to view the world with each other's perspective.

Thank you Neil and all of your team and guests. Keeping me intrigued and curious is all I could hope. Also, if I may, I should say all of you here watching this as well, with intent to learn something, are all my friend as far as I see it.

Wonderful guest and discussion!

Your last point is a question I have been trying to get answered for a long time. If my mass were compressed into a black hole, how long would it take for it to evaporate and with what energy (megatons are fine.) There should be an app or at least web page for this! Vernor Vinge, David Brin, Gregory Benford, Isaac Asimov, Hannes Alfven, Leo Szilard, Catherine Asaro, Charles Sheffield, Dr. Neutron Star - Robert Forward in the White Tux himself, Stephen Baxter, and Carl Sagan all did great Novels! I looked up Dr. Levin's SF Novel, it is way high-concept and ambitious!

Neil: “Does a beetle ever look up?” Me: “Yeah, when it flies into the air.” lol Honestly, this video was incredible. Thank you for having the conversation and sharing it with all of us. It’s really exciting to learn more about the unseen as we uncover a deeper understanding of what we are and what is currently happening in our universe.

I love Janna. I've been reading her articles and interviews for decades

I am thoroughly enjoying this episode!

Janna Levin & Brian Greene are my absolute favorite guests!1

Maybe if we closely examine a universe that isn't locally real, we might discover that space and time are not actual entities. Instead, what we perceive as space-time is essentially just measurements of distance and relative speeds.

By definition a molecule of H2O is water, it may not be recognizable with the properties of water at the macro scale, in fact as water separates we call it vapor or steam.

Janna is one of my biggest celebrity crushes. She's gorgeous and brilliant.

Great Show, Cracking Guest too. Thanks too ALL 👋

Thanks! Brilliant and informative as always. Also, you both are getting sleepy! Your coffee is on me!

You guys further my knowledge of space. It terrifies me and I love it 😂

One of the best episodes, and that is saying A LOT!

One of my favorite thought experiments is assuming that there is no gravity, and that the force we attribute to gravity is simply due to time gradients.

I love when Neil is out-smarted by a guest (Rare!). Janna is amazing. Chuck is hanging in there and keeping things humorous as usual. Love it!

This lady says gravity doesn’t fundamentally exist. Terrence Howard said the same thing. Difference between them. One has a degree and one use to be an actor.

I think we can all agree that episodes with these juicy topics deserve to be much longer @StarTalk

Love listening to this lady! While I'm neither a scientist nor a mathematician, I'd give just about anything to spend a day sitting down and talking to her.

Holy moly. How the resolution at which you look, changes how you think about reality. And again: just think about how smart Einstein was.
