Yeah, I asked my older brother what was at the end of the universe when I was younger. He told me “a wall”. I asked , “What’s on the other side of the wall?“ My brother, “cows”
The commonality from microscopic to universes is the trajectory spin orbital that's what we have in common with..... That trajectory spin orbital is present in every trillion cells the human body possesses that trajectory spin orbital is present in every human on the planet walking that trajectory spin orbital is present in all living and nonliving entities rocks or birds or bugs or water or mountains are all created with a trajectory spin orbital the universe itself is a trajectory spin orbital that mimics perhaps the helical of DNA to postulate we know what the edge of the universe is is ludicrous but we can hypothesize by probability it's either spherical unorganized organize or endless and finite or as an infinite boundary that we the common people will never ever be able to explain or prove
There’s an episode of BBC horizon from around 2004 that dives into the consequences of infinity, it is a complete mind f*ck. Everything that can happen has and will happen... if infinity is real then somewhere I just shit myself and guess what, you did too.
Infinity is what to you? That anything can become anything at anytime or that anything will become it's infinite form in it's infinite time? So...that's only two forms to infinity. What if infinity has many different forms...what if infinity has infinite forms?
Just think of this; probabilities mean absolutely nothing if the universe is infinite. Therefore all of our calculations are basically useless in the long run.
Ger Loke there are a lot of theories regarding infinity. One being an explanation for quantum wave function collapse. That when the superposition collapses into a particle or wave that the other state doesn’t actually disappear but splits off into another multiverse and that this happens for every single event that occurs. I can’t give a good explanation of this because I’m not nearly versed enough but I also seem to remember reading that some infinite’s can be larger than others, possibly having to do with decimals. Whatever it is though, is nuts. Infinity is impossible for us to really conceive in our heads at the end of the day.
@@Movebetweenthesounds Quantum probability is provable in math. But the length of time involved is just beyond our comprehension. Like the theory that our universe will eventually be a dead empty place without any cohesion to even hold particles together anymore. Then after an insanely long period of time, a highly improbable thing happens...another big bang. Hurts the head.
I don't like that idea, because that would mean, that the expanding dimensional shockwave would overlap infinitely on that donut shape, which could potentially work like drawing a line on a mobius loop and wiping it shortly after,leaving no mark behind, just a short bit of line that is being drawn and then removed over and over again. Donut means infinite in a closed loop, which would probably kill us, if space expands faster than light (with some theories suggesting that it can reach infinite speeds, the longer the expansion progresses). I mean, how often did we (the universe) die so far in our life time? Not at all (at least not all at once), which makes me imagine that space expands away from us (and with us) in a spherical shape.
Every single letter of the Hebrew Alphabet/Torah comes from a the torus. It's really mind blowing stuff if you start to analyze it, but not many people know this.

How old are you if i may ask? I'm just curious, S. Korea has one of the worlds best school systems and you say you find it "boring". I was born in Canada my family moved to the US where i grew up and went to school. And, this is just personal experience, but i had a lot of fun in High school - university. So ages 14-22. My education was genuinely fun. My physics teacher used to work for NASA. My English teach was a Pulitzer prize winner. My Social studies teacher was an ex american spy and knew stuff about the US's relationship with the USSR that were totally true but i couldn't confirm it until 25 years after the cold war ended. I was learning this only 15 years after, but i did check and 10 years later *he wasn't lying*
Also, i can't speak for the idiots who support trump but i can speak for the rest of america in saying sorry if trump fucked things up with South Korea's ability to resist Chinese influence in the region. I'm concerned North Korea being accepted into the fold is just a tactic to keep the worlds eyes off of north Korea while "The Kim's" continue to act exactly the same way. I feel so bad for North Koreans. Its one giant concentration camp except for a few people right at the top its horrible.
@@forgefathereli8354 What are you talking about he didn't ask anything about this topic. Stop Forcing your view. What makes you have the right to speak for the entirety of America? This is a video about space no political comments should be made.
"mostly all of us know, this is not true" - that almost slipped under my rader... you have always such a polite and nice manner of expressing yourself! :)
if there's one thing that never fails to impress, it's the complexity and just how amazing the universe is. Physics, you are amazing. This is why my favourite youtubers are people like you and Isaac Arthur.
infinity expanding into nothing is such a confusing concept also its sad to think that we'll never know like probably even 1% of what there is to know about the universe
The big problem here is that humankind seems to not accept de concept that we just - don't know - and all explanations are just speculations. The people have a tendency to say that the universe is 14 billion light-years of age or sometimes 14 billion light-years of diameter, but the truth is that we did not scrutinize the whole sky (that is with this finality also infinite) and that that portion of the universe probably also expanded along this period. The chief of the Juno mission recently said that all what they thought that they knew about Jupiter was wrong, if we cannot theorize correctly on a planet so near to us, what about the entire universe! Dark matter and dark energy are not a matter and energy, but a meter of how big our ignorance is on what is governing the universe.
@@hexadecimal973 you will also find half life 3 there, but you would have to use ms edge to download it, and you know how the connection there is really bad
Love this channel. I took an astronomy class in college(had to use physics and calc) and at the end of the semester we went to an observatory which could give us a pretty good view of Andromeda and mars polar caps. So neat! It was the Three College observatory in Graham NC.
I dont think there is a physical edge of the universe, since the universe is expanding, and the further to the edge of the universe you go, the faster the expansion, and if you go explore the edge of the universe, before you reach there, you will see that the expansion speed is approaching lightspeed, and even beyond at some point, which means at that moment, every atom beyond that point is move away from each other faster than light can travel, in other words, you wont see anything but pure darkness, and I cant imagine anyway to overcome that. Which is like I said, there is no physical edge, but in a visual sense, the point where everything moves away from each other at lightspeed would be the edge
I don't think that atoms can move away from each other faster than light. Atoms are matter and according to Relativity the mass of an object increases the faster it moves. This means that at the speed of light, the mass of an atom would be infinite. So long before it reaches 1c, every atom would've turned into a black hole already. I don't think that the expansion of the universe has something to do with the expansion of the objects (or atoms).
@@nuclearping but you forgot that speed is relative, the speed of expansion of space is also a different thing than the speed an object has on it's own. Someone travelling near lightspeed can will still see light traveling at lightspeed. When atoms move away from each other beyond speed of light, the atoms themselves dont have the speed, but rather it's the tearing of the space that's faster than speed of light. For example, the galaxy very far away from us is moving very fast, but that doesn't mean our mass and their mass increase because of it. Speed of space expanding is not speed of an object moving
correct me if im wrong but i gather that the current presumption is that if you teleported to that remote galaxy on the observable edge, and then looked around, you'd likely now be able see another 47 billion light years worth of universe beyond that point, and you could possibly repeat that ad infinitum, taking 47-billion-light-year steps without ever hitting an actual edge
This is a very interesting, yet quite common, thought experiment. The possibilities are that you: 1. Eventually meet a true edge (what are its features -- does it repel you or do you fall into an abyss?) This seems like a flat-earth type universe 2. It loops around and you eventually can arrive back where you started 3. You keep on hopping, seeing something different each time Did I miss any possibilities?
@@CamaradaMarcos At the end of the day nobodys wrong they just interesting theories which are just that until proven with solid and conclusive evidence..
If we take the balloon idea into account, it does NOT go on forever. It wraps around 4D space, in a hypersphere. Pick any direction and go straight in a perfect line, and you'll eventually loop back.
My money is on space curving itself in such a way that any attempt to reach the "end" will only result in being turned back the way you came or simply traveling along the edge.
yes, I've had this thought as well, but this would imply an "edge", even if that edge just means space-time curves and basically sends you back the way you came if you try to go further, which doesn't seem to be true. I guess we may never know
Technically, the Universe can be considered "flat" though. Personally, I think most "flat-earthers" are trolls, because they were largely ignored until I see comments and videos complaining about them.
@@leonardwei3914 Uneducated people are incapable of meaningful discussion on most matters, therefore will take any attention they can get, even the mockery. They're best ignored, but alas, many of us (me included) can't resist the urge to poke them with a stick now and then. Oh well, humans, eh.
I really love when Neil smoke'deGrasse Tyson talked about being awake at night thinking about what parts of the observable universe we "lost" to the expansion. And so interesting to think other intelligent life like us would be looking for other life, but will never be able to observe it.
Correct. Everything is only different versions of You, rather 'I'. ... I write the songs that make the young girls cry.. and when 'I' look out through your eyes I'M young again even though I'M very old...
Also, physics don't work at a universal speed, so the faster space moves, the slower the physics in that space work. This is actually why time exists... Kinda... There is theoretical science that points to the possibility that the expansion of the universe is actually the passage of time, and vice versa. "like how objects look farther away in three-dimensional area".
It's all just assumptions in the theories. You can make whatever assumptions you want. The best theory is the one that minimizes and simplifies the assumptions. Einstein initially assumed the speed of light was a constant in all reference frames. This is all good in SR, but In GR, to keep the speed of light constant, you have to warp space and time. There is, possibly, a better answer. You could make an alternate theory where space and time were consistent, but it would complicate other things.
I'll never forget the eureka feeling I had when I learned the basics of how stars glow. I had never really thought about it, and learning about the fusion, and equilibrium of push and gravity, and the cycle through red giant to white dwarf or supernova to neutron star. That was the biggest learning moment I can think of in my life.
I remember when I was little wondering the same thing. Imagining speeding through the vastness of space in a straight line and how it would be possible for it to continue forever. Now several years later I have come to believe that our universe is just inside something else, a building block for a larger universe. We are probably a subatomic particle of a larger universe. It's very logical when considering we can only see things down to a certain scale and same goes the other way. Humans I find don't like to think this way for some reason, I guess they feel like it belittles them but even the Milky Way does that if it were all that there was in the universe.
Also we may be able to see in the future how big the universe simply because entanglement shows no regard for speed. Maybe there's a universe debugging dimension or something.
There is a club at the end of the universe , its called club at the end of the universe , that is where ppl from around go to despair just before the end of the universe . Its probably going to be included in next patch
I Think You & I Agree that when you reach the Edge if the Visible Universe, you would find yourself in the Center of the Visible Universe. Again. And Again. We Only See an Ancient Bubble of Light.
I believe the universe has no end, but at some point there will be no matter, no stars, no galaxies, no planets, just an endless nothing, and imagining this _nothing_ gives me goosebumps
We don't know yet whether it's like that or matter goes on and on forever in every direction. I'm not sure which option is more puzzling, to be honest.
Curiosity for speculation. 1) Plank time zero nothing exists. 2) Plank time one everyting exists (concentrated). 3) Do Plank distaneces then get longer or does 4) Universe add Plank distances. f plank time "zero" there is nothing
Kind of fun, as you talk about beyond observable, that your hand every now and then disappear behind this "horizon". Thank you for making the incomprehensible more accessible. Maybe you could sell T-shirts, hooded jackets and mugs with your logo on them? Maybe make a competition for artists to elaborate on your logo or something else that you could use for promotion and merchandises. The price could be a signed photo of you, such a T-shirt or an imaginary planet created by you.
When I was a young child in elementary school during Solar system studies my teacher kept arguing with me and raised her voice at me when I kept saying "maybe there is some life on another planet" 💖🌎💖
Electricity is light as it is a plasma thru a conductor. So Birkland currents exist in space from the properties of electricity. The edge of the universe is the infinity of a toroid.
It was interesting to know how you got interested into astrophysics. I could Identify myself a lot in what you said. My fascination started later than you but I would keep trying to imagine how the fabric of space worked, what would make gravity work the way it does. And here I am, studying Astronomy in a local university. Thanks for making this channel and sharing your fascination to others.
Interesting. Guess I kinda knew this but you put it together. Dr Neil has said that what keeps him up at night is that many many years later when the galaxies are no longer visible, people will imagine what is out there, and that he wonders what we could have seen billions of years ago that we can no longer see.
I remember those questions, too. My Mother answered, that either the Universe is infinite, or there will be an end, and behind is nothing. Just nothing. No air, no blackness, even no empty space. "But we cannot imagine it. Nor the infinite universe, nor the end with nothing behind". I remember, like you, how I lay in bed and thought it will blow my mind. You know, beetles have less dimensions than us. If they fall into a bowl or so, they only would need to go up or start to fly, and they could escape. But they cannot imagine this. They always go round and round, even if it is a flat plate. If there us a rim, they are caught. I often think this is like in our case with the edge of the universe. We cannot imagine 'what lies behind', because we miss the sixth or so dimension. And the second thing is, that we will never be able to look over the visible edge; what we think is the edge isn't the real one at all. And we will always think we are in the middle, because we can look around. It is so difficult, but I love it. It haunts me somehow, and so did it with my late Mother. Many greetings! I really enjoyed this clip.
Teleporting somewhere about 40billion light years away from us would be a time travel to the past. So amazing, yet scary a little bit. How amazing our universe is!
I think it would be possible to reach the end even if it go faster than light cause the "environment" also "bring" you with itself (witch is a fact that is never considered in this subject), that + your actual speed should do it ( near light speed or even better subspace ftl)
It would be really cool if in a far distant future we could map the universe and see outside of our edge with the help of other alien civilizations who were birthed near our edge
I like your video cause I also had the same thought 6 months ago. We can travel by steps. It all depends on 2 things; The speed of light and eyesight. The better and further the sight the bigger step you can make.
James webb...2006...2012...then 2016...now2021....then 2024...then cancelled !!!!! Freaking gov... six I been waiting vigourously... sick of waiting waiting .... I will be past the edge ..b4 webb goes up
The way I understood it when I was younger was basically that, we live on a planet (big), which is in a solar system (much bigger), which is in a galaxy (much, much, much bigger), which is in "the universe" (which is everything)... and that the universe is "infinite", meaning (obviously) that it has no end. By that definition, the universe has no edge, and there is nothing outside of it (the universe being defined as "all possible existence", or "all possible reality"). The concept that this "thing" which we comprehend as "spacetime", is NOT "infinite", and is expanding into "something else", or into "nothing at all"... must change that definition of "the universe", or imply some other "unit" falling in between "galaxy" and "universe" (in terms of scale), since the universe should include "everything". This leads me to posit that... the "big bang", did not create "the universe", but merely created this thing that we refer to as "spacetime" within "the infinite universe". In other words... the big bang was not the creation of the universe... merely an event which occurred in it. And, I imagine... that would raise much "bigger" questions than those which we already have.
The universe(balloon) is expanding into time dimension which is measures in imaginary numbers "i". The universe is also assumed to be isotropic if it is positively curved which would be analogous to your expanding balloon that means going one way you will come back to your starting point, then you would have a finite size of the universe at any one moment in time.
@Cosmic C-Stellar It clearly doesn't because the completely uninhabited area of Australian desert that is shown has massive areas of light indicating cities that simply do not exist. In fact where it shows night lights are where the telescopes are built due to there being nothing around to cause light pollution.
Time is an important variable in this thought experiment. If you could travel in an instant to a distant part of our universe, you would likely see something that looks very much like what we see here.
_I don't know so no one knows_ and _I have no idea what scientists think so I'll act like I do and criticize them_ is not how any of this works. You don't get a pass on ignorance by claiming _can't win, don't try_ and you don't get to justify yourself as clever in the process.
All the accumulated knowledge we have of the universe is about the equivalent of watching .0004 seconds of a 4 hour movie. And concluding you know the plot, charcters and outcome.
i was about to say something similar. i laugh at those who claim they know what it is. "this is what you would see at the edge of the universe! i know because google told me!"
There is no edge as there is not center. Everything is the edge and center at the same time? Think of the universe as a balloon. place a dot on the balloon's outer surface before you blow it up, or inflate it. The balloon is actualy one singularity point. now you atr at its center and outer edge at the same time. Now blow it up and you'll see that everything moves away from you fro your place at what appears to be the center. You can only see the distance to the point where the balloon curves which equates to the limit of observable universe due to the limitations of the speed of light. Now since the balloon experienced inflation and our center seemed to not have moved, when in fact we have also moved on the outer side/edge of the universe.
Time, past and future. So we will never see the universe as it is now, only as it was in the past. Its just too imaginally big. The black holes in the universe, hold the greatest key in understanding the universe.
11:40 "it ends up hiding things at the edge of the observable universe", as his hand slips past the edge of the green screen barrier and disappears. Classic unintentional satire. Love it.
maybe if we ever figure out - spooky action at a distance, we can make a phone call to someone at the edge and they can call someone at their edge and on and on
Always good to see you Anton . You do a great service in showing interesting , educational , videos . As opposed to the empty , rediculous programing others are producing . Thank you.
Hi Anton! About expansion of the universe. I do not think that the existing mass and energy is a constant. Particles will form instantly by the dark energy or dark matter, and therefore new material, gas, molekules and so on will form. The universe will not become dark.
If we travel exactly as fast as light does, and we go to a planet soo far away, when we look back to our planet from that planet, will we see the exact moment we started travelling?
@@nilsman4994 Imagine that someone is waving at you and then you travel for like 30 years at lightspeed, when you look back to the planet, that guy is still waving at you.
this was part of a question i was asked once if u were looking at a mirror and traveling away from it at the speed of light what would u see? its an interesting thought experiment for those that have never before
+Cid Sapient I'd Imagine you wouldn't be able to see anything in front of you if you were traveling backwards at light speed. If you are traveling the same speed as light, then how could the photons reach your eyes?
Yes you would. Its the same thing that we would see materials very close to the edge of an black hole but in reality they went in the black hole millions of years ago.
When I was a kid of the same age around 1990 in USSR everyone told everyone that the universe was “infinite”. At least it sounds like it was some kind of accepted “view” when parents had to explain it to kids
I suspect that you can't actually get to 'the edge of the universe' because it took a billion years to get to the point of the universe where you could actually see things (due to the previous dense cloud of neutral atoms blocking light), so if you were capable of catching up to the expansion rate, you'd see darkness that you can't get through.
It is very depressing knowing the big scale of the universe. Not because it is big or infinite but because it’s so big that our existence is irrelevant to the knowledge we may discover about the nature of space.
