- Beautiful Science Video: • Scale of the universe ...
Cary and Michael Huang Animation: www.htwins.net/
Is the universe infinite? Visualizing infinity. This is part 2 of the Planck length video. if the Sun was the size of a Basketball, Proxima Centauri our nearest neighbor would be 4500 hundred miles away. And there are 10 sextillion such stars in the universe that is 1 followed by 22 zeros. And each one of them is approximately the same distance apart from each other as proxima centauri is from the sun.
In fact, the universe is bigger than even what our most powerful telescopes can see. How big is the universe in terms of numbers? And in fact, could it be infinite? Is there any way we can even begin to visualize what infinity is?
At 1 quadrillion meters, We will be passing by the Oort cloud which is thought be a spherical shell consisting of up to 2 trillion comets that surround the solar system. This spherical cloud starts about 1 trillion kilometers away from the sun and ends about 15 trillion km away from the sun. This also forms the outer boundary of our solar system, where the gravitational influence of the sun is minimal to non-existent.
The Milky Way galaxy is about 106,000 light years across, or almost exactly 1 quintillion kilometers, containing up to 400 billion stars. There is nothing particularly remarkable about our galaxy. It is a typical spiral galaxy. There are billions of others like it in the universe. Our neighbor the Andromeda galaxy is larger, containing 1 trillion stars.
When we go 1000 times larger than this, we begin to see the super structure of the universe which is made up of superclusters. We live in such a structure called the virgo superstructure. We reach the end of the visible universe at about the scale of 10^27 meters. The observable universe has a diameter of about 93 billion light years or 1 x 10^27 meters.
The reason it is actually 93 billion light years across and not 13.8 billion light years is because the universe has been expanding for the entire 13.8 billion years, and due to the cosmic expansion. And we can calculate the universe is actully 46.5 billion light years from us by this time. So the diameter of the universe would be twice that, or 93 billion light years across.
But we will actually never eventually see the light from that distance because in 1998, we discovered something dark energy, and learned that universe is not in a steady expansion, but rather an accelerating expansion, so that light will be receding from us at greater than the speed of light.
But could it be though that what we see can see is a miniscule portion of a universe that is actually infinite? Well, the cosmic microwave background gives us a clue. It’s the leftover glow from the big bang. One of the things that this microwave background tells us is that the universe appears to be flat. How do we know this? Scientists look for what we would see if the universe was a certain shape.
They look for the curvature of space. If space was not flat but positively curved like a 4 dimensional sphere, then we would expect to see multiple images of the same object in the sky because distant light rays would converge. In a positively curved universe, the angles would add up to greater than 180 degrees.
Data from the WMAP as well as Planck spacecraft, however, indicates that the universe is flat, or nearly flat with an error of 0.4%. A flat universe would be an infinite universe. But if the error is taken into account, then it is possible that the universe could have a slightly positive curvatire. In that case it would be finite, but would have to have a radius at least 250 times larger than the part that we can see. This would be a minimum size of (250 x 46.5==11.6) 11.6 trillion light years in radius or about 23 trillion light years in diameter, instead of the 93 billion that we can see.
This is huge, but would be much smaller than infinity. Infinity is a very large number. Imagine a very large number like a googol, the real googol, spelled differently than what you are used to seeing. This is 10^100 light years. That’s 1 following by 100 zeros.
Or a googolplex which is 10^10^100 - that’s 10 to the google power. An extremely large number. Much larger than even the number of planck volumes that would fit inside the observable universe (4.7 x10^185 planck volumes could fit inside the universe). But infinity is much much larger than either of those numbers.
#infinity
#arvinash
#infiniteuniverse
What we do know for sure is that universe is much larger than the part we can observe. The problem is we only have access to the information contained our in our tiny 93 billion light year diameter bubble that we call the observable universe. We can only infer from what we can see.
Hey Arvin, amazing video, all the feels! Thanks for the 2 part collaboration, was a pleasure working with you. Looking forward to seeing what you have lined up next :).

Dear sir read the comment and look up for the real explanation of most off the universe on a previous post hope you like.
Arvin Ash you're a star...
People in 2019: The universe is flat
People in 9200: I cant beleive they used to think the universe was flat
Optimistically that would be, "i cant believe WE used to think that"
Probably in 2100 the flat universe will already be proved wrong, or at least the theory will be updated
@spaghetti yummy gravity exists because spacetime is curved by mass = universe is round
@spaghetti yummy this is obviously just a meme dude go get some friends, a sense of humour and stop taking everything so seriously. You must be real fun at parties
People in 9219 - making videos to convince others that the Universe is indeed flat, since they cant see the curvature.
Whenever I have problems in my life I just watch one of these videos and then I stop caring about my petty problems.
Kinda gives you a different perspective, no? I do the same thing as you.
But you are jesus you should have mastered your brain

If you ever sleep in fresh oceanic breeze and under a clear open night sky watching the stars, you can easily get lost in the depth of the amazing universe, forgetting the petty problems of life on earth even those that may have been causing sleepless nights. Nature provides far healthier, better and more effective alternatives to anti-depressants. You know it when you experience the joy.

1,000,000,000,000,000,000,000,000 years later: "The universe is slightly flatter than it used to be."
LMAO
flat means parallel lines never intersect, now if a sphere is large enough and measured from a small scale it would still appear flat.
"Infinity is a really large number"
Mathematicians: *angry noises*

I was going to point out the same thing, infinity is just a mathematical concept
I'm not a mathematician, but I cringed too...

@@sarahhaugh7922 When he say flat he doesn't mean 2-dimensional, although it's a logical assumption to think that is what he mean. It means that the 3 dimensions of our universe is curved in the 4th dimension. Like if you take a plane, which is 2 dimensional and give it a constant positive curvature it will form a sphere in 3 dimensions. Same with the universe, but just one added dimension. If you take 3d space and give it a constant positive curvature it will form a 4d sphere aka 3-sphere. What we experience as 3d space would be the exterior of this 3-sphere.

If the universe is infinite and it started with the Hot Big Bang 13.8 billion years ago, how could it then have expanded to infinity in a finite time?
Great question! One of the theories is that the big bang could have been a bubble of creation in an infinite background. But you’re correct that if it was finite at one time, it cannot be infinite today. We know the OBSERVABLE universe if finite, but we don't know what the rest of the unobservable part entails.
Good point. Seems to me it couldn't possibly according to these parameters.
Infinite speed, regardless of big bang expansion+infinite space= there are some galaxies that are at an infinite distance and are traveling away from us at infinite speed, more over they are accelerating, as noted in the video WHAAAAT? How can infinite speed being accelerated?
Universe was already infinite when it began. Expansion means that if infinite universe expands two fold, then all distances in infinite universe are also doubled.
Note that universe might not actually be infinite, measurements of the curvature of space indicate that universe should be infinite, but it could also just be very large (quick googling gives result of minimum 120 billion light years 4d? radius )
Hmm The Universe Is Unlimited Which is a step more than Infinity. And this is only explainable as Flat...Unlimited flatness? But I note you said the Universe started with a hot Big Bang......? Where Did All That Heat Come From! And it is explainable with the collision of Two or More Unlimited Flat Universes? Now the Big question is Where did those Two Universes come from? Hmm
*Scientists laughing at flat earthers*
*Also scientists:* "The universe is flat"
You are equivacating two different definitions of "flat".
@@FobbitMike a bit whoosh
@@mar__k Presuming that you are serious: Flat earthers claim that the surface of the Earth is flat, i.e. the Earth is a pancake or a like a square tile, or something similar (and we occupy just one surface). This is what scientists refute -- the surface of the Earth is curved, consistent with the Earth being a sphere. Re the geometry of the Universe, it is not its surface that is under debate; rather the space of the Universe itself. i.e. Would two parallel beams of light converge, diverge or remain parallel on the very large scale (excluding the local effects of gravitational bending).

lol....i hope now you guys know why it's not considered a Planet XD
There's "objects" in the belt bigger than Pluto that have never been classed as planets, so it makes sense to demote it really.
This is literally one of the only channels that i have set to alert me. Arvin covers the most fascinating subjects. Extremely fun!!!!
Thanks for watching my friend!

Same here. Maybe when I'm fired from not writing enough computer code because of Mr. Ash, he could lend me a few bucks.
PBS spacetime is amazing as well, science asylum is good, what da math/Anton Petrov like mentioned already... so many good ones
"because we discovered something called dark energy"
That's a bit misleading. We didn't discover something and learn it's making expansion acceleration. We simply observed expansion acceleration and said "something must be causing that; let's give it a name." The name is a placeholder. We have no clue what it is, and we most certainly have not discovered it.
Scientists use the dark matter theory because its the most likely one to explain the expansion of our universe. I agree though that names are just place holders for these things and its unfortunate we cant actually know all the facts about space
A speculation....perhaps the contrary effect of time dilation due to expansion.
Its all maths and turtles all the way down!
@@XxDevilxKingxX1 You mean dark energy, not dark matter, which is something completely different.
Scientists do this all the time. Nothing new and nothing to be mad about.
Like scientists understanding that gravity isn't even a force, but continue to use the word as if it actually was a force. Humans do this all the time to make sense of things. Nothing more to it.

It's impossible to imagine the scope of our universe when you realize that the galaxies that are beyond Hubble's beady eyes are emitting light photons which have not yet reached human eyes and instruments (and won't for thousands of years).
more like * billions of years, if they even reach here at all
You mean won’t at all. The light outside that bubble will never ever reach us cos space is expanding quicker than the light can travel so it’s beyond red shifted

Hi
During an experience of flying through space (not sure if it was an OBE or a strong lucid dream) I was marveling at the beauty of the expanse before me and a spirit guide to my right said "This never ends".
Fair winds and following seas to all.
What I always fail to grasp on this topic is this: if the universe is 13.8 bil y/o, and if we can see some of the oldest galaxies as they were forming back then, and if we can then do the math and know how far away they are now (46.5 bil), why would we think the universe is any bigger than that?

Yeap thats called aleph nol number

@@kolikari3813 thank you, I was repeating something I learned from the Urantia Book.
That just makes it a finite number at any given integer of time. Its not infinity its just continual addition, always finite at any given snapshot of time.
imagine you're a text document on your computer trying to figure out how much space there is for other files.
I absolutely love your channel Arvin. Keep up the great work.
Honestly the idea of that super large universe kinda freaks me out even more than the idea of an infinite one, maybe because I can actually imagine the size (which I can't do with infinity)
It's called the Infinity Factor. Only an infinite can stop the questions of, what's beyond that?...
You can imagine the size of a universe that is TREE(3) kilometers in diameter? I don‘t think so.
Mel Hanson That‘s only because we cannot really grasp the concept of „nothingness“. As long as we equate it with „empty space“, we always ask „what‘s beyond“. But beyond nothingness is only more nothingness.

Right up there with the wonderfully melodic voice of the late Carl Sagan.
you can approach 0 infinitely by continually moving the decimal point. 0.1, 0.01, 0.001, 0.0001, 0.00001 etc. The value will continue to get infinitely smaller without ever being zero. Infinity isn't a number, its a concept.
I learned a lot, but understand nothing. That’s astronomy folks.😂
I'm convinced astronomers don't know as much as they think they do, most of this is theory and speculation. These "facts" change about every 10 years or so.
There's tons of disagreements and debate in the science community.
Hmm....I was taught...not a lot, which seemed a lot, then I observed the lot that I was taught and understood that I had “learned nothing.” Except...in the Universe Nothing is a lot, and therefore I already New everything about nothing before it was apparently taught to me! That’s the Universe folks.
I remember reading a theory somewhere that the universe is so big that parallel versions of earth could theoretically exist in this universe just due to probability on such a large scale.
This is correct because there are only so many ways atoms can be arranged. Given enough space, the arrangements will have to repeat.
You end up with Bizzaro Earth, Superman did that story decades ago. And Star Trek with evil Kirk and Spock.
@@Boogaboioringale boltzmann brain!
thomasbh : Boltzmann brain requires random fluctuations. The universe requires the same. Hopefully, the universe is big enough to allow duplication in the way atoms can be arranged. Your point is spot on and I wonder what the real deal is❣️🤯
Alright, Arvin, here's my crazy concept that came to me in the 90's: picture our world in the center of a balloon that extends outward in all directions. My initial thought was that if you could see far enough in one direction you'd see yourself staring back. But that was predicated on us existing within that balloon. The true model is to "inside -out " the balloon where anything within was now without. I think now it sounds like descriptions of the fourth dimension. I can't visualize it, which is maddening, but I can get to the point where that balloon gets flipped. If everything without is now within then it probably means gateways. I drew a diagram back then and it's satisfied me to this day. Is it nuts that I envisioned a concept I can't even "see?"
Sure, all great theories start with a guess - a hypothesis. It's thought experiments like this that have shaped science. What you should do is go further with this vision. If this was reality, how would object behave? What would we see? Is there any way to test whether this could be true? etc.
@@ArvinAsh thank you. I'll think on that. Also, does current theory on black holes indicate they affect only mass or space as well? Could mass-less data flow through the hole ? Mass less data might be able to reconstruct itself like nanobots on the other side .
"The infinity is a very large number"
There are some dead mathematicians
Rolling in their grave probably. It is a visualization technique. Infinity as a symbol is not fathomable to most, but as a very large number, at least we can begin to understand what it means.
I think Einstin and Hawkins had a apre-death stroke when they saw this video wherever they are now
@@ArvinAsh If you took a trillion to the trillionth power, to the trillionth power, to the trillionth power and repeated that a trillion to a trillionth power number of times, you STILL would have made zero progress towards Infinity.
Go to wikipedia dot org /wiki/Large_numbers and that will open a Pandora's box on the subject. There are whole realms of mathematics dedicated to the expression of extremely large numbers.
You could spend an entire lifetime writing a single number on paper and STILL be nowhere close to infinity.
Infinity is HUGE beyond HUGE!!!
Entire societies of monks high up on the mountains dedicate their whole lives on wrapping their minds around the subject.

01:39 *That's my favorite catch-phrase.*
☺️👌
Lol. Thanks my friend. I didn't plan on that becoming a catch phrase, but it just seemed appropriate in some early videos, so I just stuck to it.
About 48 years ago as a fairly young kid, I looked at some drops of water on the kitchen countertop. As I looked at the drops of water, I wondered, if each drop of water represented the universe as we know it, and the space between the drops of water represented the absolute void between, could there be other universes way out there in the void.
This thought process had me thinking about standing at the edge of our universe, looking out into the void, then looking back into the known universe and seeing all the brilliant dots of light. It made me wonder about the size of things, and how (relevant to this video) the absolute void MUST be infinite. I pondered this a lot throughout my life. I was only 8 or 9 when I started thinking about such things. It occurred to me that if the void was not infinite, then a boundary is implied, which implies two sides to a boundary. What would be on the other side?
Given this infinite scale, I supposed that indeed, it may well be possible that an infinite number of universes may exist out there in the void (I called it the Omniverse back then cause if something is someplace out there, it isn't totally void) The distances between the universes could be so great that light from them would not have travelled to us in our 13 Billion (or so) history. This also lead me to think about the limits on the ability for Gravity to be effective. What distance does the effect of gravity give up? I don't know this, but it made me think :)

Gary Turner
You were a curious kid. That's good. One of the multiverse theories is that we could be living in a kind of infinite multiverse with "bubbles" of universes so far apart that they could not be in communication with each other.

If the universe is expanding faster than we can ever travel, then surely from our point of view the universe IS infinite - even if it may not be physically infinite.
Maybe our universe 😐but what about the cosmos as a whole ?😐keep going in one Direction how far can you go ?😐how far can you get ?😐the Big Bang explains the moment of creation however their are problems with the Big Bang 😐in fact we actually don’t know if the Universe or even the whole cosmos is infinite or not 😐
Some people do drugs to get high, I just watch videos on astronomy and this guy
One of the most humbling visualizations of scale I’ve ever seen was actually just of the Milky Way, but with a box around the area our radio transmissions have reached. It’s smaller than a pea on a dinner plate. Upon seeing that, I have no doubt that there is life elsewhere in the universe, and almost certainly our galaxy. People are so sure of themselves when they say we’re alone. Considering how little of our galaxy we’ve been able to reach out to thus far, I think it’s unfair to be so closed minded.
Think of all the solar systems in our galaxy we’ve never studied or mapped, how little we’ve seen, there’s bound to be another solar system like ours, or dozens in our own galaxy. Then duplicate that for Andromeda. Statistically, there are a few in there with similar conditions to our own. Then think of all the galaxies in the local group, each one a statistical duplicate of our own. The hundreds of galaxies in the Virgo supercluster, and the hundred thousand galaxies in the Laniakea supercluster, each possibly containing dozens of solar systems just like ours. Span out further, and Laniakea appears as a dot among thousands of other superclusters, each containing over a hundred thousand galaxies, each with thousands of solar systems. Keep that going, as far as you want, and tell me, honestly, that you don’t believe there’s life anywhere else in the universe, that we’re it. Statistically speaking, there is no way we’re alone.
Planes At Paine 100% agree. I’m also atheist. I believe there’s more out there than what meets the eye.
The fact that the longest distance humans have ever traveled (far side of the moon - Apollo 13), is far less than the diameter of the sun - is mind-boggling.
I thought that we could never know for SURE that it's infinite by measuring the curve (assuming you get a flat result- if you measure a curve, then you can calculate it) but if you got a flat result, as we did, one would have to have 100% accuracy to be certain of flatness of space, and would also have to be basically sure of the ultimate size of the whole object, which are both basically impossible. Because if the result is flat, it could ALWAYS be just that our "triangle" is too small. If everything I could possibly, physically observe in my lifetime was the room I'm in now, and I measure a triangle on the floor in my room, I would assure you that the Earth is flat. I would have no idea how big my triangle would have to be to turn up a curve, because I would have no idea how big the Earth is, nor would I ever have the means to find out. Is this not true with us in the universe as well, or am I missing something?
No, you are correct, we can never prove flatness in an infinite universe (atleast with geometry) since it could always just be so big that it looks flat to us anyway.
Its really hard to prove that something doesn't exist. Since it could be somewhere you aren't looking.
@@KM-ub2rb Thank you!
I just keep thinking "It's hard to believe our planet has life on it, we wouldn't even be a thought in the blink of an eye in the scale of the Universe, not even an itch. Kind of like all the parts of the cells in our body, it's not the atoms we feel, or even the protons, or the string that binds those things, or the space in between. Then, one day, like we did with our tools, the Universe found us. It's taken billions of years, but we were finally noticed. When was that? Has it already happened, or will it happen yet? Then, if we are alive and tangible, how is our universe not? How does the universe, a seemingly empty (but filled) place, actually have the ability to produce organic material and the spark of life - on a planet, in a cluster of galaxies, capable of supporting life, when there are also a billion-billion other known (and unknown) planets that will too support life like ours?"
Moments later, I consider this:
"If life exists now, scattered among planets, what was life in the Big Bang before we all separated?"
"If the big bang is our centralized source, being a matter of time that is, and this is the reactive event, what was the material to cause the eruption of all things made, imagined, and created? Which things collided into what that caused the big bang?"
I keep imagining there was once two elements that individually contained half of everything in the universe. Two solid spheres, that contained the blueprint for the galaxy. How large would that have to be? Suppose then there are two infinite parts that passed into each other, how and why don't matter, they formed one massive orb of "everything" in the known and unknown universe, then erupted as all things reacted and exploded? There would be, therefore, parts of this eruption that existed 10^10^100 kilometers away prior to the acceleration. Given the known space between parts and how old the universe is expanding, my other question is, can we map out the direction of which other variables are expanding, as to determine a "universal center point?"
I know I'm probably sounding pretty mad, but you won't believe how much free time I've had thanks to the nCOVID-19.

Amazing video as usual! When I want to be even more baffled I try to imagine an infinite number of infinite universes.
This superb video make us feel how small we really are 🤷♂️
There’s a very beautiful video called “Star size comparison 2” on TH-cam. It goes from the size of the moon to the observable universe as if you were zooming out a little bit every time. However this one was great, more informative.
i can't believe theres a start called beetlejuice (search it up and ik spelling is wrong)
Wow we really are insignificant the the scheme of the universe. This was interesting.
Fer sure, and actually even 'insignificant' *_exaggerates_* our 'importance'.
If we can detect even a slight curvature that means the universe could be spherical but massive beyond current comprehension.
If there was at least 0.0000000000000000000000(trust me there is a lot more 0s im thinking of)1% Curvature yes
Yes, these Video's really put into perspective just how small we truly are in the grand scheme of things. In existence as well as the Cosmo's.💯 Just be happy to be conscious and able to appreciate it's vastness, much Love.

Really good presentation, finally someone that taks in a speed thats easy to follow. Every one else seems to think its a contest who is the fastest talker and try to be funny all the time even if the subject is genocide or something. No this is good thank you. igeer to see whats ahead.

I love your analogy of the universe with the ocean at night... It is quite riveting
I chuckled when I saw "Minecraft world" in there.
It’s called scale of the universe 2 he didn’t make it.

Did they really calculated how many plank units could fit in the universe??
Mind-blown!!!
more answers lead to more questions.....the most mind boggling subject in our known universe
Every single time i see the size comparison on the macroscopic or the microscopic scale i get goosebumps
If you guys didn’t see, a mincraft world is bigger than Neptune, it’s in the vid
Lol, why is minecraft even relevant?
May5Flames cause when I was watching that video in class I noticed that
3:18
Wow Minecraft world is larger than Uranus And Neptune
30.000 kilometers radius - Minecraft
A Minecraft world is actually infinite, it's just limited by computer technology to 60000km. But in the code itself there is no limit
I'm glad he explained the 93 billion light years... thing. But it's still mind numbing.
wow, I can honestly say my mind is suitably blown!!!
an infinite amount of mathematicians walk into a bar
Was it a random walk?
I had to watch this video twice.. when I got back to the error of the observable universe, being so low, but then putting that error into a curvature of a possibly inconceivably large sphere universe, I went for a 5km walk and just thought about it.. thought about all the things in that space, the number of chances of life, destruction, the history of super clusters, galaxies and planets. The actual size of the universe is mind numbingly large but the thought that just comes from something so big and unknown will always be like a drug for me that I can never get enough of.
Stunningly good work Arvin ! Fascinating to the end. One question, if our universe had a beginning 13.85 billion years ago, how can it now be infinitely large ?.. Great show!
Thanks my friend! One theory is that the big bang could have been a bubble of creation in a preexisting infinite background. But, like I said in the video, I am skeptical about the measured flatness. My feeling is that the universe is just very large, and that our instruments are not sensitive enough to detect its true size. Anyway you look at it though, it is much larger than what we can observe.
" it is much larger than what we can observe..." only in space ( x,y,z ) , or has much larger mass- energy from ours view?
He said in the video that the expansion of space itself is not limited by the speed of light
@@ArvinAsh Another issue in the theory of a flat universe, would be if our "Observable Universe" were actually at the "very outer edge" and not somewhere near the middle, as this would most certainly give the impression that the universe is some what flat. It would still mean that the "Observable Universe" is still be expanding in all directions, but give the impression of a more flat universe 🤔🤔🤔
Gadget :p expansion alone means there must be an edge. Nothing we know of is truly infinite. We’re expanding into something, so the real question is where does whats beyond the universe end.
1:59 Very accurate
I'm a little confused on how the universe could be infinite. Didn't the universe begin as a finite singularity that expanded? How could it obtain infinity after that, at best, wouldn't it just be forever approaching it?
Even after watching this and seeing the size differents,
its still amazing me that there is still a "Micro-verse"
Made of matter and energy that's holding everything together🤔-----😵
I have the "Macro--verse" to the left of me......
And the Micro-verse to the right, Here I am,
I'm Stuck In The Middle With You😅👌🏽
This keeps amazing me on how huge the universe. I guess well never find out the answer on why we exist and for what reason
Reality is just an illusion
You're asking the wrong question and so you will never know the answer. How we exist is much more solvable.

@@sumaks4878 An illusion cannot be a trick unto itself.
It makes no sense to assign a size to the universe, which is infinitely big
Excellent video. It feels spiritual in a way because when you attempt to understand numbers that big you start thinking outside your own self.
The Universe cannot be Infinite if it had a beginning.
What if our universe is just a background effect of another infinite Universe
@Donald Kasper big bang is fake, it has been proved
My opinion when I was looking into this, was that infinity doesn't really exist in reality. It's just a useful concept to solve certain problems. As a consequence, my opinion is that space is not infinite (in terms of greatest size and smallest size) and time is also not infinite.
But then the issue of rotations and Pythagoras theorem (for Euclidean geometries) probably poses a problem.
Hello Donald Kasper,
I wasn't referring to PI. As an approximate example, imagine that because infinitely small doesn't exist (perhaps in conjuction with other reasons), we have space looking like something like a monitor screen consisting of pixels. The problem is to understand what happens when we rotate objects in such spaces. It's quite well understood what happens in infinite space, where Pythagoras's theorem holds. An infinite space (ignoring any relativity curvature), would be something like a Euclidean space. Some conceptual issues also exist in regard to motion if we forbid infinitely small slices of time.
I welcome corrections as I may be misunderstanding things.
Thanks.
Hello @Donald Kasper,
Thanks for your reply.
I think I have a rough idea what you're on about in regard to your data compression paper for representing real world spatial data in a pixelated (or grid) space. I haven't ever studied mathematics at the level of a degree. However, your paper sounds a bit like how Fourier transforms represent signals in terms of many sine waves. To be honest, the last time I looked at such mathematics was during my degree. My everyday job just doesn't involve it.
So getting back to the point I was trying to convey..
On a computer screen, geometrical shapes can be seen to be rotated through time. However, because the screen is only made up of pixels, the mathematics behind it inevitably involves rounding to figure out whether one pixel should be on, or whether instead another pixel should be on. My argument was that because of my belief that the infinitely small doesn't exist in reality, a model of reality really needs to put forward a theory like one that says we live in grid (or pixelated) space, like on a monitor screen. However, we tend to think of space-time in terms of continuous number ranges that requires a belief in the infinitely small. How can we re-imagine such thoughts such that they fit well in a universe that is in some sense pixelated. I was under the impression that standard thoughts about rotations and Pythagoras's theorem, don't really properly apply to a grid-like space.
I may be wrong about some of these thoughts, which is perhaps why I've put them out there, in public, to get thoughts from others on them.
Honestly I would be suprised if the universe is flat - given the fact that EVERYTHING within the universe, is spherical... why would the universe it'self be flat.
I think you said it best with the ant comparisson, if an ant tries to measure the earth it would conclude that it was flat? Well... we are ants in this universe... that much is certain with these insane measurements we are talking about... we can't comprehend the size of the universe, maybe because we can't comprehend the different ways that the universe works... yet.
I am a die hard fan of yours now. Great videos.
There you go! Flat universe theory 😄
Subscribed. I don't know how I didn't discover your channel earlier.
I checked all of his math, he is right.
No, he forgot to carry the two.
Thanks James.
Lol I'm laughing my head rn 😂😂😂😂😂😂😂 hahahhahhba fiujujkinhgfu hahaha maaan I'm so fkn high bri
Actually there is a slight margin of error, but in a infinite universe that slight margin adds up. In other words they are completely wrong. I too did the math.
He's right i was the math
Imagine the universe as a marble, what would be out there, let’s say 10 miles away?
Other universes, just like there are other planets and stars in our solar system. Further would be even bigger groups of universes, like mega galaxies full of universes. And further? Mega universes full of universes. And further? It could be that all this is a grain of sand on some place that is unmeasurably bigger that we could ever imagine. And the world infinitely expanding. Also that would mean that our planet is full of such infinitely smaller universes that are full of infinitely smaller universes and so on...
Assuming a finite universe, literally nothing. No space, no time. It may seem strange but "space" as we know it is actually something and was created during the big bang along with time. You can't go "outside" the universe as it doesn't exist.

Great thought, also Semil.
“A galaxy of universes” Nice.
Whenever I went to the beach as a child, I used to stare at the sea horizon and believed that I was looking at a ever so slightly curved horizon (positively, ergo a spherical earth). I used to think that the sailors centuries ago probably felt the same way, but were forced to believe in a flat earth... This reminds me of the telescopes giving us data indicating a flat universe, but with 0.4 % error. Wow, a 93-billon year observable universe being just a tiny tiny spot in the entire universe.... Thank you Arvin for giving us a humbling perspective.
Minecraft world is the size of Neptune? wow that's mind boggling.
@Carlos Saraiva A flat one too.Where are all the stupid flat earthers?
Ye, just imagine the people that played for so long to actually reach that limit xD
....Maybe if you have like a hundred players all exploring different directions continuously for years.
No idea how long that would take lol
@@Broockle You can look at your position in Minecraft with the help of the console and then just teleport to the edge of its world with cheats. The end is just a big wall and after it the blocks just lose their function and you fall down into infinity.
@@JackoBanon1
I actually just checked a bunch of youtube videos cause I was curious. I realized the same thing. Very anticlimactic xD
Tho I do still wonder how it would work in a survival mode map where teleporting is not allowed. I wonder if anyone every walked all the way to the edge.
Another assumption I made initially was that the world just keeps expanding while you explore it as long as it has room in memory or something. But after watching all those videos the center of the map is always where the first player initially spawns I think. So you really only need to walk the length of the radius and you're there.
So having just 1 person will be just as good as 100.
It still takes a bloody long time tho I bet xD
With regular walking speed it may take several life times I'd imagine.
"Is the Universe infinite?" ... no it is relative :-|
What do you mean relative?
@@gerloke914 It means we have relation :)
Very happy to find Indian comment here 😀😀
my brain stopped working halfway through but I gotta say I enjoyed the video nontheless :')
The universe cannot be infinite if it had a beginning .
I wonder if there’s anything beyond the universe, it’s scary like how can there be nothing ?
Just A Fisher
There is nothing outside the universe. By "nothing" I mean there isn't space and time. There can be something, but if it is, it's something we can't imagine.
This means that if you were outside the universe, you couldn't see it, because, since there is no space, all objects are infinitely small.
Now, you may ask what is the universe expanding into. It is expanding into itself. Let me explain:
As time passes, because of the universe's growing size, the space between things gets bigger.
Let's say we have two objects: A and B.
A is 1 billion light years from B.
A goes towards B at half the speed of light.
This means they will colide in 2 bilion years, right?
Well, no. Since the universe is expanding, the space between them is getting bigger and they may never collide.
The universe doesn't expand anywhere. It expands into itself.

“Nothing” doesn’t exist. Universe is infinite
+ What if there's other Universes and the people there are wondering the same thing!?!
King Slayer
I don't believe so, because the universe had a beggining. In its first frame, it was infinitely small. Then, it started expanding. As long as it began with x size, and started expanding, it is not infinite.
iutisteli
There is no such thing as “nothing”
It simply doesn’t exist
There was always something there will always be something.
This is a self-evident truth
Hey Arvin....Truly wonderful video...
One thing I wanted to say, you nicely depicted your earned visualization in this video on the same what Krishna showed to Arjuna (please refer Indian Geeta Epic).
I wanted to highlight on infinite. We human observed galaxies are expanding, observable space are expanding..If beyond the boundary of observable space would not have much space, how these observable space will expand. Often I observed, observable space are being shown in elliptical size...No it can not be. Because we are able to see that much only so we human try to fit those space-things into that elliptical shape. There is no limit of length. It is SPACE. Here you go the literal meaning of space, means there would be space after space and so on as you nicely encrypted with the dotted markes surrounding to the elliptical shape of observable universe.
And that is where galaxies are expanding without any limitation.
Here, Can we not praise to that Supreme Power, who created these galaxies, stars and other things and left those leftovers in the universe to grow and grow infinitely and might be seeing those creations sitting from some far place. Hold on...Think.. Visualize .. Imagine. The Supreme is eternal. ☺️ Science is close to Spirituality. ☺️

But what is the universe expanding in🤔💭🤔💭
There is nothing outside. As universe expands, more space is created.
For those curious about what is just outside the observable universe. It's simple. At the edge of the observable universe, all galaxies are seen as receding at the speed of light due to the accelerating expansion of space. We have Big-Compute (Cosmic models of motion of all objects in the universe) and Big-Data (every telescope terrestrial or in space, has been recording video and data footage for decades). Combine the 2 and you can visualize a lot of space and escaped galaxies just outside the observable universe. So, next time - don't ever say that we don't know what is outside the observable universe. It's the same galaxies from the past which were in our observable universe. Simply never forget to keep the "record" button pressed on any telescope on or off our planet earth.
The most incomprehensible thing about the universe is that it’s comprehensible
Trevor..... Hmm...Wow....You just made God....comprehensible......When perhaps you should have said?....”The Most comprehensible thing about the Universe is that it is incomprehensible?”

Question here. It might sound silly if you already know the reason why, but the video left me wondering about gravity. If the sun's gravitational influence extends as far as the Oort Cloud, then how come, on a galactic scale, the stars which make up the Milky Way, or any other galaxy for that matter, gravitationally interact with one another to ensure they don't drift away from each other and galactic structures are maintained? I ask this because, our nearest neighbor, proxima centauri, lies just outside the range which encompasses our sun's gravitational field, and so how can they still gravitationally interact with one another if this is the case? Does gravity behave differently in larger scales? How are large cosmic structures bound by gravity instead of randomly being scattered across the universe? I apologise if I made some mistakes regarding grammar and/or punctuation, English is not my native language. Thanks!
See my 2 videos on "dark matter" I made about a a month ago. They will answer your question more fully. Gravitation extends to infinitely far for all bodies, but has a minuscule effect at long ranges. What is holding the galaxy together is the theorized dark matter.
@@ArvinAsh thanks, I'll make sure to check them out! :)
