No. We live within an illusion created by bonded electrons. There are other illusions but they are irrelevant to ours and do not mix (like a Caucasian beverage). I think magnetism is what you call gravity and these electrons exist everywhere at once, until bonding provides observation, within a very old circular expanse some call Tao. Our Universe is only a representation of that one's much earlier existence. ua-cam.com/video/1yXUrpj8PVY/v-deo.html
Sure we do. We think about the original formulation of algebraic quantification of time dilation which is (Ax+dt). Now we realized anything on a chalk board is time dilation… 😂
Neil deGrasse Tyson never fails to surprise me. I just looked at his younger photos lol. Such a dynamic personality. If you see this, thank you Neil for making this world a better place. ❤️
Dear Delilah, You are amazing, you are interesting, you make science accessible to the general public in a good and fascinating way. Makes me really appreciate you and your work
Photographer here. Chuck, it's called shortened or compressed perspective. Depth of field has to do with shallow (large aperture) or deep (small aperture) focus. With a small aperture foreground and background are all in focus, large aperture, subject is sharp background is out of focus. Anyway, I love the show and the interactions between you, Dr. Tyson and all the guests are both fun and so educational. As a self proclaimed nerd (could you tell) I'm glad the show exists. If, of course, anything really exists. Hmmmmm???
Deliliah was a delight. I think that she could be an excellent science communicator because her explanations were very clear to me. I hope that you have her back on the show! Chuck, I too love Little Richard! Don't let Neil poo poo your jokes.
Two comments, one serious, one tongue in cheek. The serious one: one of the reasons why I love watching these videos is because of the guests that are on, the Star Talk team always finds these really smart and interesting people. Tongue in cheek: is there a debate going in the astronomy / astrophysics community between flat-universers and spherical universers?
Yes, it's not really a debate, but a discussion. So far the evidence is more on the side of flat, but the curvature could be large enough that we can't yet determine the final answer.
19:02 This is quickly becoming one of my favorite episodes. What Chuck said made perfect sense in my head. This is an excellent example of how intuition can get someone in trouble when analyzing the universe. It reminds me of the saying... The universe is not obliged to make sense. Edit: Oh snap...Neil said the line right after I dropped my comment. 🤣 🤣 🤣 🤣 🤣
I still think the universe is a sphere but we are not trap in it like on earth, just think about it if the universe started with an explosion wouldn't you think it was going in all directions? therefore it would be a sphere.
@Awilmy Martinez Perhaps if it were a "spherical explosion." However, I don't think we really know for sure. Therefore, until we get the answer to that question we really have no idea as to if everything from the Big Bang does fly in all directions. For all we know, the explosion could have angled everything in one or two directions only. We just don't have an idea for sure.
@W Rowe yes! Especially with new evidence of black holes spewing mass from their "poles" one might assume the universe was spewed, big banged, whatever, from 2 poles cone-ing in opposite directions?? 🤩
Been watching you for a few years Neil, but I had to send my first comment today: How awesome is Delilah? She explains things in a way that us layman can understand. She’s a rising star!
@@luke515 In Babylon 5, the Minbarri Delenn stated that "we are the universe, trying to understand itself." Makes perfect sense to me, especially since it took 14 billion years for the Universe to create us (and any extraterrestrial critters out there.)
So refreshing to hear from young intelligent people who are passionate about exploring the mysteries of the cosmos. New ideas and different perspectives are surely the key to answering these questions.
4:20 wonderful callback Niel. That videoo had me in tears over this very topic, and I commented on that part the other day, so to see it here again has me giggling to myself again. I've had to rewind the video 3 times because I keep laughing to myself imagining an emotionally unstable universe talking in Chuck's voice about how it's "not good enough," but simultaneously "too good for everyone else so that's why no other universes have shown themselves." (Or that it's too good to talk to anyone else if the multiverse is real instead. Had to back up again once that popped in my mind and I broke down in laughter and simultaneously had an existential crisis. Always an adventure watching these.) So yeah, keep up the incredible work, and I look forward to the next one 🥰🤣
21:32 “flat” doesn’t exactly define a unique global shape (manifold) for the Universe For instance, the 3-Torus (T^3) can be given a flat metric, if we embed it in R^6. Indeed, just take T^3 = S^1 x S^1 x S^1 (embedded in R^2 x R^2 x R^2), and imbue it with the product metric on 3 copies of S^1 (which is a 1-dimensional Riemannian manifold, and therefore automatically flat)
Important note: Tori are not inherently curved! It might seem like the usual Torus/“donut” (T^2) could never be flat, but that’s only because we embed it in R^3 and force it to inherit the usual R^3 metric (You might notice that the 2 copies of S^1 are oddly asymmetric - longitude goes around the thickness of the donut, but latitude strangely moves around either the “inside” of the hole or the “outside” of the donut. This is because we are essentially looking at a stereographic projection of what a symmetric torus would actually look like in higher dimensions! Similar to drawing a cube on paper, where the top face is in the middle, and the bottom face is a square around it, with the edges that connect them moving diagonally outwards from the middle) Instead, we should embed the 2-Torus in 4 dimensions (R^4), by giving each generating circle S^1 its own copy of R^2 to live in. This gives us something called the Clifford Torus, which remains perfectly flat (It basically has the same metric as T^3, except with one less copy of S^1)
Love the show guys. Can’t believe you all said there was no golden ratio action in the universe. If you use the golden ratio to create a logarithmic spiral, that is the exact spiral you see in many galaxies!
What does our geometry appear like from a higher dimension.? For instance, does it seem like all of past, present and future seem like a single moment.?
Proud to see this young PHD from prestigious Princeton. Neil it's good to know we have others in the wings to continue this legacy of information given to the masses about our Universe. So freaking Kool!👀🖤🖤🖤🖤🖤🖤
Great episode, and wonderful guest! I can imagine the nervousness of being interviewed by Neil deGrasse Tyson less than 2 years after one's PhD... But the interview was amazing!
@Delilah. What is your Twitter handle? And in a separate note. You have good TV/video presence as well as the skill to simultaneously explain concepts and hold attention. The camera loves you, too. Do more TV/video spots like these. You also have a future in this domain
To have an American Lord as a co host , now that's gangster 😎. Lord Nice is the perfect co host. Dr. Gates Welcome and congratulations on your academic success. Outstanding episode Doctors and your Lordship. Big up from Brooklyn
hey. Excuse my ignorance, but I have a couple of questions: 1. If we are seeing everything in the past because of the limitations of light speed, how do we know that the universe is no longer expanding? 2.If we are located within a void, could this be why everything seems so far away? 3. are there any study or pursuit of space travel that can be solved by utilizing higher dimensions?
Just watched a Trip to Infinity and it felt like a rollercoaster ride with no Car, Tracks, or Amusement park. I thought it was very well done and Dr. Gates and others stood tall with Dr. Greene.
Outstanding episode and to Dr. Gates bravo 🙌🏽 on using the the black hole to answer another previous question brilliant. Humanity might have a chance. Thank you again.
The universe's structure is complex and fascinating: galaxies are distributed unevenly, influenced by cosmic expansion, dark matter, and the curvature of spacetime. While the concept of spacetime as a fluid is intriguing, current models depict it as a dynamic, flexible fabric rather than a liquid. There isn't a definitive center of the universe; it's expanding uniformly, which complicates our understanding of a universal center. Far-off galaxies are not reflections of our past selves but rather snapshots of their current state, affected by the finite speed of light. The universe could be flat or have a more complex shape, such as a torus or a closed spherical form. Light can't escape a black hole due to the extreme curvature of spacetime near the event horizon. As for stability, spacetime can be disturbed by massive objects and energy, but overall, it follows the rules set by general relativity. Could wormholes ever be stabilized to allow practical travel through them, and how do various geometries of spacetime influence the cosmos?
I really like this lady, Dr. Gates may not have had all the complete answers, and yet was able to give us something to think about in a deep meaningful way. I found myself thinking things out in ways I didn't even think I was capable of. A hole new light. I look forward to seeing where she goes and how many she inspired to make it where they end up.
Some people remember Mandela dying in prison and others remember him getting out of prison and dying much more recently. That's like the biggest "change" people disagree about. My favorite is, is the Mr. Rogers song "Its a beautiful day in the neighborhood." or "Its a beautiful day in this neighborhood." I remember the former but apparently it has always been the latter.
Hey Dr. Tyson, Dr. Gates, and Lord Nice, I love the show and watch both on UA-cam and listen to the podcast while commuting to work on Spotify. I like to think about physics, space, engineering, and science in general and currently work as a process automation engineer in Livermore, CA. I know that a true anti gravitational force would behave differently than this. However, wouldn't a negative differential of gravity between two points on a gravitational wave potentially yield a similar force (in direction, but would have a small magnitude) to negative gravity/negative energy? The negative differential conditions would be possible if you choose a point upon the gravitational wave that is close to the minimum of the wave as the relative observation point and then select the maximum of the wave as the other point of comparison. If my math is correct and a gravitational wave behaves like a sine or cosine wave then this should result in a negative differential in gravity. Am I thinking about this wrong, and if so what did I miss?
When you say your impression of space is flat, I think of our miniscule impression of the surface of the earth being flat when close. My suggestion is space is like a torus, a very large torus where we can only see the flat of it. But in some directional aspect it is expanding while it rotates, and in other areas of the torus it is compressing. I like the idea of this torus with punctures like your example of the tire with punctures I call black holes, leaking whatever falls into the black holes out into the larger unseen ether because we are on the inside surface of the torus which is ever rotating in its own dimensions and speed! This way matter changes in distances but nothing is changed in the quantity of matter.
So I've heard this story about black holes having gravity so strong that 'not even light can escape' and IV always had a problem with that description, because photons have zero mass. I once heat it being described as thats at the event horizon, spacetime itself is falling into the black hole at the soeed of light, and further down the black hole soace falls in the black hole faster than that, so once crossed, this gives a much more intuitive visual image of what's happening.
You're absolutely right. Light actually still follows a straight path as far as its relation to spacetime. Mass just changes that path and black holes change it so extremely that even photons that are or would be headed straight for the horizon will never reach it because spacetime is falling into the hole faster than the photon traverses it. It effectively switches time and space and the photon is traveling time in a certain amount of space instead of traveling space in a certain amount of time. But with only one velocity I suppose it wouldn't matter anyway.
What if spacetime isn’t one object, but rather two different objects moving through each other. Space / matter being one dimension, and time / gravity being another dimension that flow through each other like a mesh river. We exist in these beads of conscious awareness ((we are just space and time existing together at the same place, at the same time)), where these mesh dimensions connect creating these flowing streams . Black holes are what occur when the gravity / time in one of these beads exceeds the mass of our given dimension.
What might have been a surprise some years ago is the enormous interests for the universe, and said short all the mysteries which are bound to be a part of it. As a fellow physicist I find it so difficult because I want to learn everything now. But hard work
Do You Think We Live In A Multiverse?
Probably, to say our planet is the only planet with life or ours is the only universe would be very arrogant.
No. We live within an illusion created by bonded electrons. There are other illusions but they are irrelevant to ours and do not mix (like a Caucasian beverage). I think magnetism is what you call gravity and these electrons exist everywhere at once, until bonding provides observation, within a very old circular expanse some call Tao. Our Universe is only a representation of that one's much earlier existence. ua-cam.com/video/1yXUrpj8PVY/v-deo.html
Sure we do. We think about the original formulation of algebraic quantification of time dilation which is (Ax+dt). Now we realized anything on a chalk board is time dilation… 😂
I mean you couldn’t possibly change time based on polarity of magnetism now these days… it’s all about the sun
@@bored9260I think The Sun is merely a representation of an electron (within our illusion).

We exist in these beads of conscious awareness ((we are just space and time existing together at the same place, at the same time)), where these mesh dimensions connect creating these flowing streams . Black holes are what occur when the gravity / time in one of these beads exceeds the mass of our given dimension.
Whoah, what an awesome episode.
Love this pod!! Keep looking up! ALWAYS!!!!
Saturn was país, to save us.
Polares, our Andromeda GALAXY.
SPEEEEEED OF KISSES
What might have been a surprise some years ago is the enormous interests for the universe, and said short all the mysteries which are bound to be a part of it. As a fellow physicist I find it so difficult because I want to learn everything now. But hard work
