Asked a physicist what's beyond the universe, got a quantum physics lecture and ended up even more lost! :D

Productions like this are why broadcast TV is obsolete. Superb!

There is no edge, no end. Our brains haven’t evolved enough to even comprehend infinity.

Anyone else sleeping to these space documentaries? 😅 💤 😴 💤 😴 💤

Today i am 67 years old.10/20/1956. But by the time i was 4, i had two years of reading and started reading more complicated matter(my mom, aunt, and grandmother all educators). Even before i got into the first grade i had read Aldous Huxley, Edgar Rice Burroughs Princess of Mars, Robert Hienlens Stranger in a Strange Land, of course HG Wells, and just about any book my dad brought home of many science fiction which formed my love for science, especially astrophyics, astronomy, and questions came faster than answers were even known in the early 60s. It seems it has taken most of my life to even begin how to articulate a question in the proper context. I love these videos that may not answer a question but sure can generate more of them(questions). So, from my perspective, i do believe that there are civilizations that have come and gone just by nature but none of us know for certain even if some of us say or think or even swear they have seen things not from here(as far as we know). So is it possible that the laws of physics are completely confined to what our minds can comprehend as of this era of time we are in. What about a civilization that in its path pf development resembled our current progression but have existed and still is a viable society that is a million or a billion years older than we are? Lol it is just another question i asked 60 years ago. My dad, a former fighter pilot and retired as the Chief Systems Anylist of the Air Force would lay his books by his recliner and i can't think of any that i did not read other than Louis B. Lamore westerns which i was never interested in. But technicle manuals, science fiction novels, and on occasion those "Eyes Only" classified manila folders that i had no business looking at lol but i did. And some of those scared the crap out of me. But it did put some rocket fuel in my curiosity. Glad i subscribed to this group. Very entertaining and informative

Nothing blows my mind like the universe. I love it!

I have a suspicion that our reality is infinitely complex and no matter how many physics questions are answered, there will always be more.

63 and because of YT, I’ve become interested in this topic. Makes me feel quite insignificant. Well beyond my ability to comprehend such distances

Superb video. One of the rare ones I shall watch a second time, perhaps even taking notes. It is very informative and extremely well done. Huge thanks for putting all this effort into it. But the result shows it was worth it - at least from our point of view! Kudos to you.

I am a professional physicist, but not a cosmologist. This video is very good and scientific in every respect. It was very entertaining and educational. I will surely share it with my colleagues. Thank you for your hard work in putting this together.

The problem with finding the edge of the universe is, no matter how far we get to see, we still don't know if there is something beyond.

The universe has no age, it's continually evolving, giving birth to new stars, and will never end.

This video proves that we dont really know anything about the universe but someone does

This channel might be one of the best things that has ever happened on the internet. The quality of animation, narration, writing, music... It's far beyond what any other educational channel has ever achieved, and it somehow keeps getting better with time. I have nothing but massive respect for whoever is running this spectacle.

The more I watch these kind of videos, the more I feel we know nothing about the universe, how perfect everything is, how can such perfection come into existence without a creator, how glorious that creator must be, how mighty.

Whenever I'm about to fall asleep, and I think of how gigantic the universe is, it makes my heart pound, because I'm sure the size of the universe and what happens to us after we die are connected.

We really don't know how the universe started or how big it actually is, and quite possibly may never know. May we never stop formulating theories or lose our curiosity about unknowns.

I’m always amazed about the incomprehensible size of the universe. The vast majority is lethal to life and yet humans still think it was made for them. The hubris is really amazing.

The greatest outcome of thinking about this is not arriving at an answer but of asking deeper questions. When I was younger, I wanted concrete answers. Now, I enjoy finding a deeper question hidden within the surface question so that I may uncover an even deeper question. This why I CAN sit in a room by myself and be content.

Love this stuff. I will need to watch it repeatedly to continue to absorb what’s being said. It’s clear but it’s heavy and takes more than hearing it once to fully comprehend.

The thought of nothing existing for all eternity is frightening. Can you imagine nothing but emptiness for ever?

Well, that was far more comprehensive than I expected, even including a reference to higher dimensions at the end.

Narrator sounds like he is reading a bedtime story. Lots of aspiration.

short answer= no one knows

Could it be that the edge is actually 'the present moment' rather than a physical location? So we are already at the edge? The further you look out into space, the further you are looking into the past. So seeing further is taking you further away from the edge, not towards it.

Amazing how even today there are people who believe that every thing ends at the edge of their ability to see.

So after going at the speed of light for awhile. Eventually at one point everything and everyone you once know or knew is forever gone. A distant memory. How scary.

Infinity and eternity are incomprehensible. Mankind could, but almost certainly won't, be around for a billion years -or a hundred billion -and it couldn't even scratch an infintesimal grain of the universe's size and its volume of planets. More suns in the Universe than all the grains of sand on all the beaches and deserts - and in all the oceans - of our Earth.😮

I love how everybody in this post seems to have the answer. For some strange reason, terrified from it ! What's so terrifying? One way or the other absolutely no difference.

Sheldon: "Penny, while I subscribe to the "Many Worlds" theory which posits the existence of an infinite number of Sheldons in an infinite number of universes, I assure you that in none of them am I dancing."

One day chances are that all the maths and theories that we have now will be disproven. If you look a couple of hundred years ago what people believed about the universe compared to now, there is such a difference. In my opinion I don’t think we will ever know certain things. It’s crazy!

Infinity. One has to believe there was more than one "big bang". And infinite number of the same situations.

Nothing blows my mind like the universe. I love it!. Nothing blows my mind like the universe. I love it!.

It’s impractical to believe that cosmologists, astronomers and physicists have, at this stage in human evolution, obtained all the information they need to understand the processes which unfolded in the creation of matter. We should neither expect to believe they have somehow discovered the physical boundaries and age of this universe.

What Beyond Universe may become Unsolved mystery ever for us human... but, what Beyond Our Life surely that is a Time when all of our mystery will be solved...

I don't think any human on earth will really know for sure. But logical thoughts and ideas like this one, will be as close as we get to finding out. Making the mystery more interesting and wonderful.

The quality of the video is fantastic in 4K Ultra, along with the soothing voice of the narrator, the interesting hypotheticals, and the knowledge being divulged, thus making it a wonderful experience.

My son was 10 years old when he asked me this. Shocked me that he even thought of that concept.

Uni-verse: Uni= one Verse= to be changed, transform, to turn, to turn back Multi-verse= to convey absence of unity

I got a greater understanding and deep appreciation of the universe after watching this video

I am 100% sure that there are an infinite amount of planets with life that we will probably never reach.

This has got to be the best video I've ever seen in reference to the edge of the Universe. Absolutely love and appreciate the intelligence of human science, and, all that has been discovered, thus far..

It warms my heart knowing we'll bring cats 🐈 with us to the edge of the universe ❤

Hands down one of the best documentaries I've watched about the universe.

Thank you for putting together a wonderful and educational video that is something of quality and interest with pleasant narrative. I enjoyed this thoroughly. Thank you.

I always find it funny when they come out with some new discovery on the furthest object ever detect from their fancy mirrors but when you look at the pictures you see even more fainter dots. So what gives, how can they say that and yet more lights even further in the observations.

We can never ever know the answer to that. We take one step the Universe steps 100. Even with light speed the vastness of space is to great. We will be lucky to go beyond our Solar System.

"Dark time?" Oh my gosh! It'll be interesting to see how the ideas in this video evolve.

wow, one of the best space videos I've ever watched. simple explanation of complicated phenomenon's, great narration, and overall enjoyable. subscribing for sure

I love how this just assumes we have a clue about anything. How many times has physics said "we are on the cusp of understanding all." It's like getting the final piece to a puzzle only to learn our 100 piece turned into a 1000 piece puzzle, and it just keeps getting exponentially bigger.

The universe goes on forever in all directions

Beyond the edge of the Universe is the pot of gold we been told about!

As humans, with our physiology adapted to life here on Earth, our limited lifespans and our equally limited technology, and our current tentative "baby steps" into space, the Universe is indeed infinite! ... What lies beyond, I suspect, will ALWAYS remain a mystery? EDIT: I'm not sure what lies beyond, but I know what comes before! ... Adverts, and yet MORE ADVERTS, before the video has even got started!

I would need to watch this video an infinite number of times simply to begin understanding these concepts. Absolutely fascinating stuff...but sadly beyond my grasp.

When the brain dies consciousness dies. You will never see anyone ever again. You will not know that you are dead. Tomorrow is not promised. Tomorrow does not exist. We are all on the same sinking boat that ends in tragedy. In the end nothing matters. Enjoy today like it’s your last. Remember, It’s Just A Ride…. Bill Hicks….

Reality has the right amount of satire to really keep you bewildered

This mind-blowingly well explained for something so complex and abstract. I have no mind for maths and physics, but I pretty much understood everything that was explained here.

With infinite power comes infinite responsibility.

I have a mnemonic for this question. HEAVENS S for stars...typical feature of our lowest universe N for nebula..bigger than our whole universe E for energy.. V for vanity A for abyss E for enormous critters H for highland..the highest universe

honestly one of the best science/space vids on YT and ive watched tons of them

Excellent video on an interesting and baffling topic. The bit about the piano reminded me of the infinite improbability drive in Douglas Adams's "Hitchhikers Guide to the Galaxy".

Space never ends, thats mind blowing

We must find out the mysteries of the universe. Its better to learn about the universe than to be worried about trivial issues on earth. Wars, climate change, social injustice are not important. Who cares about that. We need more people interested in cosmology so we dont lose sight of whats truly important. Thanks to these channels that realy put the most important issue front and center

I’d be happy to lay every penny I have that the universe is FAR bigger than these so called experts think it is. It’s beyond anyone’s comprehension imo

I have to say that the Universe don`t have beginning, don`t have end, and no matter where in the universe you be, you will always going to be in the center of the Universe.

This channel is a real Gem

Ants trying to explain their existence.

I hope universe is infinite so i can watch this vid in infinite loops...might be the only way i could grasp all the concepts talked about in this very same video .

Cool and informative!! I'm going to show this to a friend who lives 50km away. Always complaining about distances. This puts it in perspective

Our understanding of space seems to be based on straight lines. That's how we see the world, in straight or curved lines. We even imagine travelling in a straight line, or a curved line. I don't think we're evolved enough to perceive an edge to space as we know it. Heck we can't even imagine what the 4th (or higher) physical dimension is like to live in. I reckon that with our limited senses and perception we'd not know the edge of space even if we crossed it.

thoughts about our universe and existing makes me feel scared and exsited at the same time. i love this feeling. but, it causes derealization. i'm searching for the answer about our universe many years, but i always find a new couple of questions. humanity won't find a right answer.. i dont think it's really possible. if our universe is infinite and has no edges... maybe everything is just a dream or lie? our life is really like a hardest game ever exist.

We live in a slow-motion explosion, which we call the universe. The light created from the collisions of debris gives us the illusion of time in an infinite space.

Let's be honest, we can't wrap our heads around what's really out there. There is as much likelihood of truly proving the beginning, as there is of observing the end. We will never know.

The universe is a hyper sphere that falls back on itself. The inside is the outside. If you were to leave the edge of the universe, you will enter the edge of the universe like going off the side of the screen on an old video game but you would be in a different time probably the future. Reason for this if you have to occupy space you can’t go out of space so as the universe curves you curve when it folds back on itself, you curve back into the universe even though you’re perceiving yourself going straight.

Your videos never disappoint. Thanks a bunch!

Hi everyone, whoever is reading this just wants to say that we are all praying for each other,

I like the idea of an infinite universe. The normal state of things is void and emptiness. Yet, anything that can exist will exist and will do an infinite number of time with an infinite number of variations, much like that spontaneous piano example. So in a way, you have always been and aways will be alive. Sure, eternities will pass between each life, but much like time doesn't exist for light, time flies pretty fast when you don't exist...

The the thought of empty space due to continuous expansion is truly mind blowing

I have been studying this topic for many years: 1) Some astronomers, not others, predicted the early stars and galaxies. This is not a problem to the Big Bang. 2) The universe (time, space, and matter) began 13.7 billion years ago, this is firm as many tools have been used to come to this age. 3) A theoretical “spaceship” could not get to the “Edge of The Universe”, as the universe is expanding. 4) At the “Edge of the Universe” is time-space curvature. The universe is expanding; space and time are both expanding. Far away objects are expanding away faster, they are not yet at the speed of light. 5) The universe we see is smaller than, what we cannot see is true. But one cannot go to infinity, just because we cannot see it. The unknown size is not infinity, but is vast. 6) The geometry of the universe is not known yet. The film does a nice job of talking about the theory. 7) The universe is not infinite. There is no evidence of other universes. To appeal to infinite other universes is to make the gambler’s fallacy. Also, infinity is not an answer, as infinity x infinity is infinity, this is to say that you can trust nothing in this universe, yet that is not how anyone lives their life. The 1st and 2nd laws of thermodynamics, tell us the universe will not bounce. 8) The law of cause and effect is real. The universe had a beginning. So beyond this universe is the one that brought it into existence, a causal agent beyond space and time.

If I were a very tiny but superbly intelligent bug that could only live inside the bark of a tree in Brazil, I wonder what the Universe would look like to me then! The sheer scale of everything is mind-numbing! Thank you very much for an excellent production!

Nobody knows when it was formed, nobody knows how big it is, and nobody will ever figure it out.

What an interesting video! I was thinking about that phenomenon where as space expands it reaches lightspeed and goes even beyond, so galaxies beyond that point would never be found. Now with this video it makes that thought a bit more comprehensible. The way it is explained and the easy to understand footage in the video, is what I haven't seen in any other video before. Much appreciated! But now I have one other thought about why we think the "Big Bang" happened at the 13 or the 26 something billion light years mark. Wouldn't the "Big Bang" have happened at the point where space moves towards us and also away from us, as that would be the center. And maybe we are at that point in space where we travel at the speed beyond light, so we could never "see" that point in space.

Gravitational anomalies that have an escape velocity greater than C have no edges and by definition are universes. If you can see one, like looking at a black hole, then that means you are in a bigger universe than one you're looking at, but that doesn't change that there is no edge. The edge of a Gravitational sphere is only approachable from the outside, not the inside.

The universe is packed with intelligent life, many like us haven't learned to traverse the huge distances, Yet. Obviously many beings have, they bend or fold space/time to travel unimaginable distances in mere moments.

Although measurements so far shows a flat universe, maybe it actually curves in on itself, so if you travel a straight line you eventually end up where you started. Maybe the distant light we can observe are actually the light from nearby stars and galaxies that did a round trip in the universe. Maybe the universe is like a house of mirrors.

It’s hard enough to even imagine what a billion light years distance looks like let alone what could be outside of this system.

I’ve seen and experienced “impossible” things in my life. It’s enough for me to have comfort in the fact that there is a God and only enough science to contain or physical minds for so long before we realize there is a creator behind all of this that will hide the answers we seek for our own peace.

Isn't the matter at the edge of the expanding universe creating it's own spacetime in which to expand into? As space seems to be a biproduct of matter. That also raises the question, if two objects become far away enough from each other, with nothing in between, wouldn't they eventually be separated by a spacetime division? As in their own pocket universes. So two things that were once sharing the same collective spacetime could eventually become far enough away from each other that they no longer occupy the same spacetime/dimension/universe? If so I'm assuming that there is no way to rejoin those objects into the same spacetime, because there is no way to bring two objects in different universes/spacetimes "closer" together. Is it possible that that is what other dimensions and universes are? If matter is creating spacetime to expand into at the edge of the local universe, could that constantly expanding vacuum be causing the acceleration of the expansion of the universe? Those aren't theories, those are actually questions for anyone who knows the latest theory.

I imagine a bustling flow of ships coming and going from a port.

Fantastic, interesting, entertaining, understandable, really great video in all facets, thank you!

Hard to contemplate that there is nothing, probably no other universes as well. Very scary to be alive.

I’m now a Flat Universer and we don’t have a visual distance limitation like explained in the video. In reality around 60 billion lights years out there is a black barrier going around preventing us from going over the edge and hiding the light of everything behind it.

I think it's impossible to reach "the edge" of the universe in our experienced space-time. The faster we go and the closer to the edge, the further it extends before us. I've only tried it a few times, though.

Perhaps the key to achieving faster-than-light travel in space lies in transcending our conventional notions of space and acceleration. It may entail adopting a perspective that involves manipulating space-time, such as creating a wormhole, rather than attempting to surmount seemingly insurmountable distances through traditional means. It's intriguing to consider that the solution to this challenge could be profoundly counterintuitive and initially unrelated to our familiar understanding of travel.

What’s beyond whatever’s beyond the universe and what’s beyond that? What is the universe inside of? What are all the multi and parallel universes inside of? What is THAT inside of? What’s beyond THAT?

Best regular person explanation of the universe expanding into nothing: if our current universe eventually suffers heat death and even black holes fade away, than there is effectively nothing left in the universe. Some particles will pop into and out of it, but essentially there is nothing in every direction. Now if another big bang happens and a new universe starts to form, it’s expanding into the nothingness that was our old universe. The people in that new universe would have no idea that a previous universe existed, and would believe they are expanding into nothing. This cycle could happen forever. If that doesn’t work for you, Futurama did a great Time Machine episode that visualized it.

I think of it as a computer game where you also unlock a world map. At first they are black and meaningless, only when you hit them do they become visible. The ever-present and therefore infinite NOTHING only becomes meaningful when one does SOMETHING with it, such as looking at it, naming it, etc. The question is who started calling NOTHING the NOTHING so that the NOTHING existed in order to create SOMETHING. Like the first light.

I've always felt we use the word infinity any time we can't comprehend something. I believe the universe is just significantly bigger than we think. Every few decades we learn significantly more than we did in decades before and it changes what we know of space. The knowledge we had back then often times turns out to be completely incorrect and we laugh at how ignorant we were, simply because we didn't have the tools or the brain capacity to observe and measure to the scale we needed to. If space was truly infinite, how we would be able to see the start of it and know the big bang was 13.8 billions years ago? Would we not be able to see the start if it really was infinite? Also how can we measure the plank heat as being a finite number, if there was infinite mass to push into space for infinity? Wouldn't the heat at that point not of been measurable?

Our understanding of the cosmos is more unpredictable than the weather patterns. God created the cosmos with a purpose and asked us to worship him to fully appreciate his true magnificence.

I must admit that at around half of the video, I wasn't really following the logic of the argument anymore, despite the clarity of the speech. Anyway, nice video!
