Seeing that the nearest star to earth is 22.8 trillion miles away, and there are more stars in the universe that there are grains of sand on all the beaches and in all the deserts in the world, the universe is close enough to infinite to me.
I think the point is that the observable universe is so stupendously big that it is almost pointless to try and imagine any additional space beyond. No doubt there is more, but what we can perceive is already quite a bit beyond what we can understand.

Its always a humbling experience to think about the universe, and its enormity, or infinity. We humans are intelligent beings, but not enough to comprehend the universe. Brian Cox is incredible to listen to.
The universe is not infinite, the only thing that is infinite is nothingness, the place where nothing exists, but because nothing is there it doesn't actually exist. Therefore the universe can expand into the nothingness creating a bigger universe because there is nothing there to stop it. It's a bit like numbers, once you have counted to the highest number ever, there is always a number that comes after it
Brian Cox somehow has the ability to take the incomprehensible nature of the ever expanding infinite universe and boil it down to something I can almost understand. Him and Neil are some of the universes best gifts to us.
@@TheSunTheSea Bill Nye has been saying the same thing since the 90s when he had his show on PBS. He hasn’t changed his message since before he was popular.
Many can't understand infinite universe while I can't understand a finite one. When ever I imagine an end, the next question I have is what's behind it.
Amazing! Someone using their brain for more than a hatrack. If the universe is infinite then there are an infinity of particles out there, which is a logical and mathematical impossibility.
@@captainplacard9666 Maths and Physics don't exist proportionally in every place and at all times for an entity like universe.. Our laws of Mathematics and Physics might very well be limited to only our own planet and solar system. Everything we know about things outside our solar system is based on estimates and guesses using our planet's laws. What if the laws are different in other places (which very well is possible as there are extremes like quasars and pulsars in the universe, even the entropy) So in short, everything is a guess using our own laws. And our laws can't define everything. Either all our calculation is 100% correct about the universe or it's 100% wrong, and I believe we are not purely correct, because even our current laws can't define more extremes we find in the universe properly.
@@captainplacard9666 That is neither a logical nor mathematical impossibility. To say such would be to say that infinity is mathematically impossible, which is demonstrably false.
That's a question that has haunted me most my life! When I first learned of the solar system, galaxies, and the universe I was told the universe was infinite. Just the word infinite makes me queasy. I was happy to hear Brian say nobody can visualize infinite because I've tried for 60 years and haven't wrapped my head around it yet.

i can kind of wrap my head around space being eternal and infinite. What really mind fucks me every time I think about it is where everything came from and why things are the way they are. Why do elements like iron and carbon exist? Why do electrons and protons even exist? why when you mix hydrogen and oxygen together do you get water? space being an endless void of nothingness makes sense to me. When you throw in chemistry and physics it all just completely blows my mind

Interesting. Are you familiar with biology? Once you see how biomolecules are organized into cells, tissues and systems it becomes mind boggling how complex living beings are
No. The most mind boggling part is how these pieces of meat stuck on a little speck of nothing in some forlorn corner of it all managed to ACTUALLY figure out.

@@havenbastion 'Time' is there to confuse people. Time is creating of humans and is measured by number of times our Earth turns and goes around the sun. That 'time' has nothing much to do with universe. It only our measure. If there is intelligence they would probably measure time totally different. It could be meaningless to them. If they have other ways to regenerate their bodies they would use that to count time of regenerations etc.

Well it depends on your definition of 'Universe'. If your definition of Universe is the black space in the Heavens between the Galaxies - then yes - it goes on forever in every direction possible, in my estimation. I mean where would it stop? Is there a wall preventing any further exploration beyond? If there is a wall - then what lies beyond that wall? The Universe is infinite.
And to think that despite our observations of light that took 13 billion years to reach our telescopes from the photons perspective it travelled no distance in no time..... That is a mind bending thought....
@@swbrl2843 Because "popular" can mean different things to different people, especially when applied to scientists (i.e. many people couldn't name a popular scientist).
After listening to Brian’s discussion toward the end… the number of galaxies and then the average number of stars per galaxy… taken to the next level, the potential number of planets, it is very difficult to imagine there are those who believe Earth could be the only planet with intelligent life. It would be a genuine “miracle” for that to be the case!
Well if the Earth is the only planet with life on it and the Bible is actually true, that would be the worst possible outcome in my opinion. But the evidence against the Bible is near enough infinite and the mass burning of all Bibles and other ludicrous religious texts is long overdue. However 95% of the world still clings to these fairy tales and they refuse to learn anything beyond those antiquated pages of violence and contradiction.
@@TheMadScientistOfLuton I’m always amazed by the words of people who do not understand the biology of human nature. That’s right… biology. There has never been a society, no matter how large or small, that has not had a biological need for religion and a life purpose greater than one’s self. Personally, I am not wedded to any particular religious belief. However, I am quite certain that there are intelligent powers greater than human beings and that the Universe is not some mega-giant cosmic accident. Thinking otherwise is the pinnacle of human arrogance.
@@Primus54 I disagree. There’s no such thing as a 'biological need' for religion. Yes, most (though probably not all) human societies have held some version of a broadly religious belief system. But how does that demonstrate a ‘biological need’? And how does it indicate that this intangible power you hold claim to actually exists? The evidence we have from studying ancient societies is that humans have believed in a huge variety of batshit crazy nonsense. Almost all of them are mutually incompatible, and almost all relate to their local environment. This indicates we have incredible imaginations, but doesn’t demonstrate any need for religion, let alone it being ‘biological’. What we do have is a need to understand and explain, because when we do understand something we feel safer and more in control. Without an explanation, there remains an uncomfortable and anxiety inducing void; a void that we fill using our human creativity. This is why we used to invent supernatural explanations for disease and the weather. Medieval doctors didn’t understand plague so they invoked God, or some other baloney. Now that we understand infectious disease, or lighting, no one invokes God as an explanation. Human nature leads us to feel safe with simple explanations, and we also feel safe sharing common purpose, beliefs and superstitions with our social groups. These traits would have been extremely adaptive in our ancestors, but they don’t reveal truths. People are still doing this today, creating explanations for phenomena they are unable to comprehend ourselves - hence Qanon and other conspiracies. Yes almost every culture has followed a religious belief system. The trouble is they are virtually all wildly different, incompatible and geographically specific. If there were some sort of cosmic truth driving this ‘biological need’ don’t you think religions would converge to be more compatible, and more universal in scope? And if there isn’t a cosmic truth in some way driving this ‘biological need’, why would a ‘biological need’ exist? There is absolutely no evidence of a ‘biological need’ for religion, but there are biological, psychological and sociological explanations for the preponderance and durability of religions. Read up on evolutionary exaptations and spandrels to understand how biology can adapt a particular trait, only for that trait to be co-opted by something completely different, like religion. You said this: “I am quite certain that there are intelligent powers greater than human beings and that the Universe is not some mega-giant cosmic accident. Thinking otherwise is the pinnacle of human arrogance.” I disagree, completely. You are basing your belief on a combination of two logical fallacies: ‘God of the gaps’, and the ‘Argument from incredulity’, and you’ve offered no evidence whatsoever. It’s you who is demonstrating arrogance: You profess knowledge on a fundamental idea, yet you can provide zero evidence, and as I’ve shown, your reasoning is flawed. Claiming you are certain about a fundamental truth, while being unable to demonstrate or justify that claim really is the ‘pinnacle of human arrogance’. You only have to look at history to see that.
I can't express enough how grateful I am for your channel. Your videos have helped me understand complex scientific concepts in an easily digestible way
This is a comment I made elsewhere but I will put it here too since I think this is quite an interesting physical/astronomical/philosophical/biological problem. I will try to describe my view of what "time" is: In the physical reality the only time is the present. However, the present of any given point in space relates to any other given point at the speed of light. The effect of this is that there cannot be a universal present where everything exists at the same time. For example, if the earth and the sun are separated by eight lightminutes earth's present and the sun's present are eight minutes apart in either direction. None of them is before or after the other, it's just a separation of causality. For me, this solves the problem with an infinite universe since it is not contained in a simultaneous present. It makes terms like "the observable universe" pointless as it becomes nothing more than an optical phenomenon. The concept of a "time-line" with a past and a future in addition to the present is entirely a product of the brain. In fact every process of the brain as conciousness, memories, language, perception etc is a tool in the process of creating the experience of time passing. But how can things be happening all the time(!) if there is only the present? Planets, particles and energy are allowed to move about because they travel across those points in space I mentioned earlier. And as they do that they enter that point's present which is separated from the previous position at the speed of light.
Very interesting theory of "time," which I also intuitively sense as a construct of our perception. Your theory makes sense to me on the level of relativity of "now" between two points in space at whatever distance. Are you using the speed of light just as a convenient reference unit of measurement in comparing the states of those two points, or do you see it as intrinsic to the shared reality of those two points? Also, how would your model explain the perceived "2 years" between the present when you posted your comment and my present reply?
I like the point of infinity as an option. It's a point that stretch's our understanding of thought and maybe lead to stronger understanding of many things. Understanding infinity seems to be impossible at the moment. A lifetime can be dedicated to it but unfortunately none of us live for eternity to see if our understanding is correct.

I went to see the lovely and soporific Brian Cox live in St David's Hall, Cardiff, in about 2019 🤔 His voice and the subject matter were so soothing that I nodded off. When I woke up I looked around, and both of the people I was with were asleep, as were the people all around me.
I can't wrap my head round the possibility of space being infinite, There must be an end. It's crazy to think what happened before the big bang, It's almost impossible to know?
If the universe really is infinite than every single atom that makes up our body and brain absolutely will come back together at some point and we will be reborn. That’s a absolute fact. And as soon as we die it will be like a snap of a finger and we will be alive again
Imagine, absolutely “zero” of everything. No universe, no matter, no space, no time, no existence of anything. Can you imagine it❓❔❔❔ I tried it and it freaked my mind out.
That is exaaaactly what im thinking about every day. I can't imagine the non-existence of the universe or us humans, it freaks me out too. But the question is: What exactly does non-existence look like? When everything is black? Meanwhile the time would still pass, but that would also mean that something HAS TO exists to know that.
It amazing to think when i was born the telescopes of the mid 70s were lucky to see a few billion light years. Now there up to over 60 billion light years now. I can't wait to see how much further the next generation of space telescopes will extend out the range😊😀
They say the James Webb Space Telescope will give us a pretty good idea of whether or not other life exists in the universe. I don't know which scares me more: there is, or there isn't
You're right. I'm far from scummy. Scummy is as scummy does. I don't invade people's privacy and then judge them by something that is none of my business. I don't lie to people about things that are real and things that affect them. Who is the real scummy person here?
When I watch them, they are knowingly in front of cameras that broadcast their performance to millions of people. When they watch me they are invading my privacy in a primal way, but they're too brainless to understand that.
If we know that it's infinite then the possibility of advanced alien life is guaranteed, it's also technically guaranteed that there's a exact clone of you somewhere It makes a colossal difference

By definition something that has a beginning cannot be infinite. Something that is infinite doesn't have a beginning nor an end. So, if the matter in our universe had a beginning, it is finite. But what the "universe" is expanding into might be infinite and already there and always have been.
No, the idea of an infinite universe is going to be related to the idea of an observable universe, the idea that we are simply in a small physical bubble in a universe with infinite amounts of different bubbles, there's also the theory that our universe is expanding because we are in side of a supermassive black hole and that the big bang was the forming of this black hole, this means all matter in our observable universe was simply pulled in through an event horizon, this mostly explains why the oldest visible matter looks like super hot particles which is what you would get in the aftermath of a supernova explosion. This is unfortunately the worst possible outcome due to the fact that it means we can never see outside of the event horizon and thus finding out how the matter in the universe came into existence prior to being pulled into this supermassive black hole we call our observable universe is impossible.
@@SuperYtc1 "The universe did not start with the Big Bang...There was actually a universe already existing before it and the Big Bang was merely the end of that universe" He added that evidence of that previous universe can still be observed today.

@@Rikimkigsck There is literally so much evidence for a big bang/big expansion that saying there wasn't is just silly. Use what the evidence is telling you. The idea of a universe existing before the big bang ending and creating this universe has next to no evidence, so if you believe that it's more faith at this point, no one knows.
I believe that there on an infinite number of parallel universes all with exact copies of every being on every planet in these universes. However, time is different in each. I believe this helps explain that feeling of deja vu. When you experience that feeling in this universe at this time, it is a memory of something you did in the universe the you were in before. Also, things that you do right now in this universe at this time will be a feeling of deja vu for your exact copy in the universe that is behind this one. When our body dies in a universe your consciousness leaves your body and joins you again in another universe. This exact copy of ourselves really isn't that exact, by exact, I mean your consciousness is exact but your body and life experiences are different. I often have dreams or feelings in a POV thought of me living in different times in different places, they are quick dreams or thoughts. One I have more than others is my POV of walking up some cement steps to a door with blinds on it, its an office of some kind. I can't explain it but I sense the time is in the 1950s in North Carolina, I was not born until 1963 and I was born and raised in California and have never been to North Carolina. I also get feelings of me living in the south some place in the 1930s. I'm in a kitchen looking out the back door to a very large back yard with green grass and I'm frying chicken and getting ready for a big back yard party. These feelings are so vivid. Life is strange.
And dreams. Who are these "real" looking people in my, our dreams, streets, homes, buildings, situations? Another part of us living some place else maybe? So interesting. 🤗
I'm sorry but having dreams about other lives doesn't mean you have had other lives, neither does it mean you're somehow detecting yourself in other universes. Really strange logical leap which is the kind of logical leap religious people use.
@@KM-leons Not true. Space is expanding faster than light (and accelerating) which means it is impossible to ever reach the edge of it, there will always be universe ahead of you even if you could travel forever, so it could well be infinite that sense. And because nothing can travel through space faster than light, the Universe is infinite to everything that could ever exist within it.
@@DaBIONICLEFan Just because the universe is expanding at a speed higher than the speed of light and cannot catch up with the edge of the universe it's infinite? Did you successfully finish high school? I am sure you need to go back to school and you should learn the meaning of "finite" and "infinite".
@@KM-leons Dude, it's exactly what infinite is. If you travel through something, and even in an infinite amount of time never reach an end (as is what happens in our Universe because of its expansion), that IS infinite. Because there is always space beyond you, no matter how fast you travel or how long you travel for. The Universe has also been measured to be perfectly flat with an absolutely miniscule margin of error, which only bolsters further that is infinite. Now just because you don't like that, it doesn't mean you have to be an arsehole to me.
The more i research about universe the better version i see of myself . And i would like to say that know about our universe you will be highly fascinate by this thing .
If time is infinite then we existed infinite times. Its too much coincidence that we exist in the PRESENT for the first and last time. Its like winning lottery 100 billion times in row with the sane numbers
Infinity is the best and only answer about the universe. It removes all other questions such as who or what was the creator...how old is the universe...where does it end etc...
In another word, if the universe is not eternal, and finite, you must face the question of a beginning, a creator. Simple logical questions will start to contradict each other in the existence of infinity. Like Can you count to infinity? what is infinity minus 1? Therefore a finite universe is far more likely than an infinite one.
@@MichaelZMD Just because you can phrase a question such as "what is infinity - 1" does not mean it is a valid question that has a valid answer. It certainly does not support your conclusion that the universe is finite.
@@RobDeManc You are actually making a good case for the impossibility of infinity. It shows that infinity is just a concept for us to cope on large numbers. And if infinity is a real quantity within the universe, it must obey the same rule as other quantities. such as 10-(10-1)=1. But ∞+(∞-1)=∞, which does not correlate with the reality within this universe at all. The only explanation is that ∞ is a concept, not real.
It seems to me that every point of observation - that which observes the observable - is itself a priori infinite. Infinity is a tacit quality of observation... of conception... of deduction. The very act of observation confirms - or at the very least implies - infinity. Only the observable is finite. Only materiality is finite - the measurable - that which we portray as space & time... whilst observationality transcends all that is finite.
I love the hypothesis that we exist in a black hole. And that there are tens of millions of black holes we can see. It’s conceivable there are tens of millions more black holes outside of ours. It also answers why we can never escape our universe. It gives us boundaries but also makes reality infinite at the same time.
Excellent. To assume the observable universe is the whole thing just perpetuates the history of wrongly assuming we are at the center of everything-- going back to the belief that the sun revolved around the earth. Each time, we learn we are wrong and the extent of the universe keeps expanding. Infinite or finite? Can our minds comprehend either possibility??
Well yeah it’s infinite. Let’s just say there was a brick wall at the end of the universe..well, what’s beyond that brick wall? That’s the beauty of it all. It’s a never ending book
"Space is big. You just won't believe how vastly, hugely, mind - bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space." DA
The universe is incomprehensible. I wish we had more answers. And even with the answers we do have, it’s impossible for me to wrap my head around how unimaginably big the universe is. Even if it is finite what lays beyond the Universe? The fact it probably just goes on and on forever is crazy
I believe that the most exciting time in the history of any living civilisation, is when they can explore the galaxies as easily as we explore holiday destinations on our planet today. Oh how I would love to live in that time.
Finally a simple & accurate answer. If we ever even begin to understand it , it will take longer than the brightest minds can imagine with our current knowledge.
Most people mistake Space for the universe. Space is absolute in the spatial sense, No origin, no end and no horizon ,but the Universe was created within the space from a Singularity. What astronomers mean by expanding the universe , the increasing space between two celestial objects .
When people talk of the universe, they always seem to be talking about the visible universe, you know - all the "stuff", the debris from the big bang. What interests me is all the blackness, the "black void" that all that "stuff" (galaxies, cosmic dust etc) is expanding into. Has that black void always been there? Does it just go on for Infinity? Is there a point where it ends and you punch through to a parallel universe? It's all so strange. I don't think science has an answer for this.
The universe is not infinite, the only thing that is infinite is nothingness, the place where nothing exists, but because nothing is there it doesn't actually exist. Therefore the universe can expand into the nothingness creating a bigger universe because there is nothing there to stop it. It's a bit like numbers, once you have counted to the highest number ever, there is always a number that comes after it
I believe we still need a million more years of human evolution and technological advancement to truly answer this question. What we can see and what we know might as well be but a single drop in the ocean.
@@Carlking3 Everything is possible. We might go extinct in the next 10 years, or we could very well manage to colonize the entire universe. A billion years from now we might still be around.
You can infinitely divide remaining piece of something by two as infinity and you can infinitely divide remaining pieces in two as infinite infinities within infinite. There is a philosophical infinite and a scientific infinite. Scientifically based on our math, nothing can be infinite so the million years won’t change anything. But human life can be infinite in the mind of a fruit fly. If that fruit fly became intelligent in the next million years, it could look at our lifespan like how we understand the lifespan of the stars. We will never find Scientific infinity in a number, but in a concept, that we can circle a globe for infinite number of times.
@gooberboots We are all different, some can't think beyond their church, other dream with exploring and knowing everything our amazing universe has to offer.
If the universe once had the width of a planck length, and then expanded into a grain of sand and then into an orange, size-wize, how could it after a mere 13 billion years have become infinitely large, or how could it ever grow from finite to infinite? The universe is not a divirgent series, or if it were, it would still be finite as long as it wasn't infinitly old.
You are conflating space and the universe….. these are 2 different things…. Space is finite, as you could reach the end of it before it expands further if you had the technology to fly faster than the speed of light within the UNIVERSE we live in….. and the universe consists of space, matter, and everything else that is beyond that…. As we still don’t know what it is beyond space itself, which is why we named it dark energy… so dark energy is actually the never ending substance or concept that we know and love as infinity, it is truly the only infinite “thing” we know about, and guessing what is beyond that is borderline insanity, as even if there was something else, it too would be endless and so forth.
@@pdj2995 Your notions of universe, space and dark energy seem to me somewhat unusual. Etymologically "universum" means "every thing turned into (versum) one thing (uni)". In modern cosmology everything is understood as being contained in space, and when the universe expands, it is actually space that expands with the things it contains. The expansion of space is not subject to the lightspeed limit, thus two things can, in virtue of being in space, have a relative motion faster than the speed of light. The notion of dark energy was introduced to "explain" the observed accelerated expansion of the universe. By general relativity alone, the initial expansion referred to as the Big Bang should have slowed down, but as the expansion of the universe was observed to be accelerating, Dark Energy was the name given to whatever causes the acceleration.

How can people be upset about the theory that universe is eternal?? If there was a beggining, then there will probably be the end... so it would be cool that universe is eternal in that case - life could be eternal...
is it possible that the "inflation" we "know about" was actually the first sentient being looking up into the sky and forcing the "wave" universe to move to a state where everything had to "settle" because it was observed? Sorry not using the right terms I know. What I mean is, like quantum physics where nothing is "set" until observed.
This is a conflation of the meaning of the word "observed". Observation is probably better termed as an interaction between wave functions that causes the wave to collapse. Sentience has nothing to do with it.
Brian Cox is a great science educator. It still blows my mind, though, that so many scientists refuse to believe in God. The universe is perfectly designed for life, yet these people simply won’t acknowledge a creator. Instead, they rely on untestable, in my opinion, things like a incredibly huge universe, that sweeps way beyond the cosmic horizon to explain the universes flatness, 10 to the 500th universes or whatever, to explain the fine tuning, etc. Don’t forget, if you find a watch on a beach, it implies a watchmaker.
I am reminded of Katha Upanishad. ' He who think he knows, knows not. But he who knows ,he doesn't know ,knows. Also the external mystery. ' The tongue has never soiled it '
I think if we knew more about the universe it could fry your brain imagine the complexities we as humans aren't designed to understand this kind of information
There is no edge, you just end up back where you started with. Just like an ant travelling in 2D around the Earth's surface would end up back where it started, if you travelled in 3D through space you'd end up back at Earth.
@@Nitrous0x The universe appears flat to us but that could easily be because we're only looking at a tiny slice, not big enough to capture the curvature. Just like an ant thinking the Earth is 2 dimensional by observing the distance between the top and bottom of the garden and seeing no curvature. Our universe could be like that but just scaled up a dimension. We maybe have to look harder in 3 dimensions to see it's actually 4 dimensional.
It's amazing how people believe in all this space universe stuff but are incapable of making the most obvious observations about where they live. People will believe anything if comes from someone who they believe to be an authoritative figure.
if something is not infinite and is only close to infinity then it is actually not close to infinity at all because infinity will keep on going while what is 'close' to infinity will keep on falling back
Think about it: if there was an actual "beginning" what was here before that? It's the most mindblowing concept you can conceive of: to not have anything: no space, no time, no matter. But it's obvious there couldn't have been a beginning even if there was a big bang because that implies linear time which is really a subjective human perception. You can't have a beginning if there is no time. And how could it be finite? That would mean something outside the finite universe: but whatever that would be would be part of the universe. Therefore it's infinite. Unless you define the universe as just THIS universe and if it has a "boundary" what's on the other side of it. But that's using the concept of space-time and human perception of it. The reason for existence is nothingness is too scary for "God" so therefore there is something rather than nothing. Now what happens when we die? Reincarnation? And if so could we be reincarnated in a different galaxy? That's where Alan Watts comes in.
To put it simply to us human beings, yes. To what we imagine godly powers to be like is far beyond what we could even conceive of. So it most certainly is to us
This is ten percent luck Twenty percent skill Fifteen percent concentrated power of will Five percent pleasure Fifty percent pain And a hundred percent reason to remember the name
This will always bother me. Where even did the empty space for the big bang to happen inside if come from? How is it that nothing that had always been before can suddenly spawn everything that there will always be? Regardless of our knowledge or findings it will always be a rabbit hole of what created that which we found to have created. Beyond comprehension.
Same. I can't wrap my head around the idea of "nothing" and "infinite". Everything has a beginning. The empty space for the big bang to happen inside wasn't just "nothing" and it couldn't have existed infinitely. Something must have created that empty space for the big bang to happen in the first place.
If the universe or cosmos is finite, what is its barrier and what lies outside its barrier or limitation? I cannot imagine anything but infinity. It is like existence is within, for example, a ball or a box, if so what is outside that ball or box?
The universe is not infinite, the only thing that is infinite is nothingness, the place where nothing exists, but because nothing is there it doesn't actually exist. Therefore the universe can expand into the nothingness creating a bigger universe because there is nothing there to stop it. It's a bit like numbers, once you have counted to the highest number ever, there is always a number that comes after it
I love these videos! Whilst it's impossible to get your head around what i find intriguing is how everything is so organised in earth, the water, sand, beaches, life etc etc sun and moon near us not so near us etc
@@joewalker1501 Because it will show more of the same, meaning that the cosmic background will be the same at this new higher level of resolution. I don't know what the big bang theory predicts with regard to what the JWST will find, but i also predict they won't find it.
Quick question. If the observable Universe began from a singularity, is 13.8 billion years old and nothing travels faster than the speed of light, how can the Universe have a radius of 46 billion light years?
Nothing "in" the universe can travel faster than the speed of light. But the furthest parts of the universe or space itself that we can observe and measure are moving away much faster than the speed of light. And accelerating.
Because the universe expands from each point in space in all directions and at a great enough distance the sum of all this expansion does actually exceed the speed of light.
When the universe first “popped” into existence approximately 13.75 billion years ago, spacetime itself began expanding at speeds faster than the speed of light. This period, called inflation, is integral in explaining much more than the universe's size.
The universe must be infinite, there’s no question about it. Our Galaxy is nothing more than a spark rising from a campfire, but something had to exist to start the fire.
It's analogous to a jigsaw with a piece missing, you know the shape you know the size and you know where it goes..... you just have to find it and that is what they're trying to do
@@hughjarrse I get that, but they look at the sky and see the same stars 10 times, as its lensed from other stars and galaxies. We just think we can map it all out to make some kind of sense to how we assume it should look. If space isnt so flat, and there are places of lower, or higher density space, how do we know what it will do to light, we make these wild assumptions and i do love a good theory, don't get me wrong. But half of it is just made up to fit some mathematical model because there was some hole to a story they can't explain without it. Truth is we can't even imagine the true nature of reality and the extra dimensions. All we know how to do is put some numbers into an old equation so it works.
@@ObiWanCannabi 100% right, but we can only look with the intellect and technology we have, theories always start with "what happens if we do/add this" It you create a model and (for instance) add value to account for dark matter and whenever you run that model the results look good it's legitimate to look for something to match your hypothesis, hopefully you will find it. The Higgs particle was theorized long before it was found. I'm hoping neutrinos are the answer, they're my favourite subatomic particle (you haven't got a fave...sort yourself out) because they're all left handed, which probably means Paul Reed Smith hates them 😉
It often amazes me to think about the fact that the universe is actually only 13.8 billion years old. I mean, the number itself is not that big at all. A modern CPU can already have that many transistors on it, for example. It's a vanishingly small number, really, even when compared to, say, the number of atoms in a grain of sand, which is at least a few quintillion.
Imagine the universe is just 3 sun years old. it's just so young and our galaxy is one of the youngest galaxies. I think Sir Roger Penrose is right. The universe has always existed and it's expanding forever thus it's probably infinite.
What if our universe was inside a blackhole. Meaning our universe was created when a black hole was born. And all blackholes in our universe are other universes. There are quintillions of them.
@@Rikimkigsck but if its expanding, doesnt it have to be expanding from, and to a point? meaning its not infinite, i dunno though lol im no scientist, or is it only "infinite" because were are tied down by the rules of physics?

@@madelynhernandez7453 A finite universe actually doesn't make any sense. If you say it ends at some point, it only ends because something else begins, which again means there's more stuff outside of its boundary, and if there's more stuff then it's is a direct contradiction to a finite universe.
@@spbalance finally someone making my point. God, its incredible how many people just stop thinking after saying "there is nothing behind it" like wth? Nothingness is also something, in order for something to "end" there should be the beginning of something else behind it. Like saying there is nothing behind the walls of my house.
yes. If there are at least two points in space, one can always in either direction, smaller or larger, go beyond the previous measurement. Time is a function of space, it is a measure of space, so therefore one can (if technologically possible) always measure smaller or larger.
Yes my friend and i thingkh like you...And i want to know how the u infinite is the notcreational and eternal in the same time?Who creted the infinite eternal's self who is the notcreational and eternal infinite natural perfection?😇😇😇
Regarding the size of the Universe, here's a theory I heard: When the Big Bang happened, and shortly afterwards, the 'energy', photons, whatever that expanded out started transforming into the matter that would eventually become galaxies, and, eventually, some components would become the Milky Way, the Sun and Earth etc. At the same time, light was also escaping/going away from the Big Bang at, you guessed it, the speed of light. Forward to present day Earth. When we look towards the Big Bang through our telescopes, one can argue that we are using / seeing light that has taken billions of years to reach us. BUT The original light of the original Big Bang, when Earth, and pretty much everything else, was barely an amount of photons or energy, passed us by millennia ago. So, it could be argued, are we looking at The Original Big Bang? Or 'just at a really really big explosion that occured billions of years ago, in an even larger Universe? Did we just come from a Big Bang within an even bigger Universe? Just an idea.
I never found the end of it…and never met a Being that has. After awhile…you get tired of wandering around and you call a place…Home. Some just have…a larger view of home than others. For some…it’s a house. A town. A city. A planet…
so theoretically, the universe would only be "infinite" to us who are bound by the laws of physics, but, if there are such things in existence, wouldnt the universe become "finite" for beings who are not bound by the laws of physics? IE if you could travel faster than light, you could theoretically go to the very edge of the expanding universe. I dunno, i need to stop smoking pot and watching these videos at the same time lmao

Amazing! Someone using their brain for more than a hatrack. If the universe is infinite then there are an infinity of particles out there, which is a logical and mathematical impossibility.
@@captainplacard9666 Maths and Physics don't exist proportionally in every place and at all times for an entity like universe..
Our laws of Mathematics and Physics might very well be limited to only our own planet and solar system.
Everything we know about things outside our solar system is based on estimates and guesses using our planet's laws. What if the laws are different in other places (which very well is possible as there are extremes like quasars and pulsars in the universe, even the entropy)
So in short, everything is a guess using our own laws. And our laws can't define everything. Either all our calculation is 100% correct about the universe or it's 100% wrong, and I believe we are not purely correct, because even our current laws can't define more extremes we find in the universe properly.

After listening to Brian’s discussion toward the end… the number of galaxies and then the average number of stars per galaxy… taken to the next level, the potential number of planets, it is very difficult to imagine there are those who believe Earth could be the only planet with intelligent life. It would be a genuine “miracle” for that to be the case!
Well if the Earth is the only planet with life on it and the Bible is actually true, that would be the worst possible outcome in my opinion. But the evidence against the Bible is near enough infinite and the mass burning of all Bibles and other ludicrous religious texts is long overdue. However 95% of the world still clings to these fairy tales and they refuse to learn anything beyond those antiquated pages of violence and contradiction.
@@TheMadScientistOfLuton I’m always amazed by the words of people who do not understand the biology of human nature. That’s right… biology. There has never been a society, no matter how large or small, that has not had a biological need for religion and a life purpose greater than one’s self. Personally, I am not wedded to any particular religious belief. However, I am quite certain that there are intelligent powers greater than human beings and that the Universe is not some mega-giant cosmic accident. Thinking otherwise is the pinnacle of human arrogance.
@@Primus54 I disagree. There’s no such thing as a 'biological need' for religion. Yes, most (though probably not all) human societies have held some version of a broadly religious belief system. But how does that demonstrate a ‘biological need’? And how does it indicate that this intangible power you hold claim to actually exists?
The evidence we have from studying ancient societies is that humans have believed in a huge variety of batshit crazy nonsense. Almost all of them are mutually incompatible, and almost all relate to their local environment. This indicates we have incredible imaginations, but doesn’t demonstrate any need for religion, let alone it being ‘biological’.
What we do have is a need to understand and explain, because when we do understand something we feel safer and more in control. Without an explanation, there remains an uncomfortable and anxiety inducing void; a void that we fill using our human creativity.
This is why we used to invent supernatural explanations for disease and the weather. Medieval doctors didn’t understand plague so they invoked God, or some other baloney. Now that we understand infectious disease, or lighting, no one invokes God as an explanation. Human nature leads us to feel safe with simple explanations, and we also feel safe sharing common purpose, beliefs and superstitions with our social groups. These traits would have been extremely adaptive in our ancestors, but they don’t reveal truths. People are still doing this today, creating explanations for phenomena they are unable to comprehend ourselves - hence Qanon and other conspiracies.
Yes almost every culture has followed a religious belief system. The trouble is they are virtually all wildly different, incompatible and geographically specific. If there were some sort of cosmic truth driving this ‘biological need’ don’t you think religions would converge to be more compatible, and more universal in scope? And if there isn’t a cosmic truth in some way driving this ‘biological need’, why would a ‘biological need’ exist?
There is absolutely no evidence of a ‘biological need’ for religion, but there are biological, psychological and sociological explanations for the preponderance and durability of religions. Read up on evolutionary exaptations and spandrels to understand how biology can adapt a particular trait, only for that trait to be co-opted by something completely different, like religion.
You said this: “I am quite certain that there are intelligent powers greater than human beings and that the Universe is not some mega-giant cosmic accident. Thinking otherwise is the pinnacle of human arrogance.” I disagree, completely. You are basing your belief on a combination of two logical fallacies: ‘God of the gaps’, and the ‘Argument from incredulity’, and you’ve offered no evidence whatsoever.
It’s you who is demonstrating arrogance: You profess knowledge on a fundamental idea, yet you can provide zero evidence, and as I’ve shown, your reasoning is flawed. Claiming you are certain about a fundamental truth, while being unable to demonstrate or justify that claim really is the ‘pinnacle of human arrogance’. You only have to look at history to see that.

Lmaoooo. I relate to this comment so much. Thanks for the laugh. 🪐 🛸 🌙 🌎
He somehow manages to sound intelligently confused 😂
This is a comment I made elsewhere but I will put it here too since I think this is quite an interesting physical/astronomical/philosophical/biological problem.
I will try to describe my view of what "time" is:
In the physical reality the only time is the present. However, the present of any given point in space relates to any other given point at the speed of light. The effect of this is that there cannot be a universal present where everything exists at the same time. For example, if the earth and the sun are separated by eight lightminutes earth's present and the sun's present are eight minutes apart in either direction. None of them is before or after the other, it's just a separation of causality. For me, this solves the problem with an infinite universe since it is not contained in a simultaneous present. It makes terms like "the observable universe" pointless as it becomes nothing more than an optical phenomenon.
The concept of a "time-line" with a past and a future in addition to the present is entirely a product of the brain. In fact every process of the brain as conciousness, memories, language, perception etc is a tool in the process of creating the experience of time passing.
But how can things be happening all the time(!) if there is only the present? Planets, particles and energy are allowed to move about because they travel across those points in space I mentioned earlier. And as they do that they enter that point's present which is separated from the previous position at the speed of light.
‘Time’ is the human invented concept of measuring the motions of space..
spaceandmotion
Very interesting theory of "time," which I also intuitively sense as a construct of our perception. Your theory makes sense to me on the level of relativity of "now" between two points in space at whatever distance. Are you using the speed of light just as a convenient reference unit of measurement in comparing the states of those two points, or do you see it as intrinsic to the shared reality of those two points? Also, how would your model explain the perceived "2 years" between the present when you posted your comment and my present reply?
I like the point of infinity as an option. It's a point that stretch's our understanding of thought and maybe lead to stronger understanding of many things. Understanding infinity seems to be impossible at the moment. A lifetime can be dedicated to it but unfortunately none of us live for eternity to see if our understanding is correct.
Stretches.
The universe is not infinite, the only thing that is infinite is nothingness, the place where nothing exists, but because nothing is there it doesn't actually exist. Therefore the universe can expand into the nothingness creating a bigger universe because there is nothing there to stop it.

I went to see the lovely and soporific Brian Cox live in St David's Hall, Cardiff, in about 2019 🤔 His voice and the subject matter were so soothing that I nodded off. When I woke up I looked around, and both of the people I was with were asleep, as were the people all around me.

By definition something that has a beginning cannot be infinite. Something that is infinite doesn't have a beginning nor an end.
So, if the matter in our universe had a beginning, it is finite. But what the "universe" is expanding into might be infinite and already there and always have been.
No, the idea of an infinite universe is going to be related to the idea of an observable universe, the idea that we are simply in a small physical bubble in a universe with infinite amounts of different bubbles, there's also the theory that our universe is expanding because we are in side of a supermassive black hole and that the big bang was the forming of this black hole, this means all matter in our observable universe was simply pulled in through an event horizon, this mostly explains why the oldest visible matter looks like super hot particles which is what you would get in the aftermath of a supernova explosion. This is unfortunately the worst possible outcome due to the fact that it means we can never see outside of the event horizon and thus finding out how the matter in the universe came into existence prior to being pulled into this supermassive black hole we call our observable universe is impossible.
@@DomzyDX What you said doesn't disprove his point. The universe cannot be infinite by its definiton.
I think Sir Roger Penrose is right. The universe has always existed and it's expanding forever thus it's probably infinite.
But we know the Big Bang happened 13.8 billion years ago.
@@SuperYtc1 "The universe did not start with the Big Bang...There was actually a universe already existing before it and the Big Bang was merely the end of that universe" He added that evidence of that previous universe can still be observed today. "There was something before the Big Bang and that something is what we will have in our future," He added, "We have a universe that expands and expands, and all mass decays away, and in this crazy theory of mine, that remote future becomes the Big Bang of another aeon."

I believe that there on an infinite number of parallel universes all with exact copies of every being on every planet in these universes. However, time is different in each. I believe this helps explain that feeling of deja vu. When you experience that feeling in this universe at this time, it is a memory of something you did in the universe the you were in before. Also, things that you do right now in this universe at this time will be a feeling of deja vu for your exact copy in the universe that is behind this one. When our body dies in a universe your consciousness leaves your body and joins you again in another universe. This exact copy of ourselves really isn't that exact, by exact, I mean your consciousness is exact but your body and life experiences are different. I often have dreams or feelings in a POV thought of me living in different times in different places, they are quick dreams or thoughts. One I have more than others is my POV of walking up some cement steps to a door with blinds on it, its an office of some kind. I can't explain it but I sense the time is in the 1950s in North Carolina, I was not born until 1963 and I was born and raised in California and have never been to North Carolina. I also get feelings of me living in the south some place in the 1930s. I'm in a kitchen looking out the back door to a very large back yard with green grass and I'm frying chicken and getting ready for a big back yard party. These feelings are so vivid. Life is strange.

@Khashi Khashi, you very well may have lived many many lives. 🤗

If the universe is 13.8 billion years old and it began from a singularity the universe cannot be infinite for obvious reasons.
@@KM-leons Not true. Space is expanding faster than light (and accelerating) which means it is impossible to ever reach the edge of it, there will always be universe ahead of you even if you could travel forever, so it could well be infinite that sense. And because nothing can travel through space faster than light, the Universe is infinite to everything that could ever exist within it.
@@DaBIONICLEFan Just because the universe is expanding at a speed higher than the speed of light and cannot catch up with the edge of the universe it's infinite?

@@KM-leons Dude, it's exactly what infinite is. If you travel through something, and even in an infinite amount of time never reach an end (as is what happens in our Universe because of its expansion), that IS infinite. Because there is always space beyond you, no matter how fast you travel or how long you travel for. The Universe has also been measured to be perfectly flat with an absolutely miniscule margin of error, which only bolsters further that is infinite.

Infinity is the best and only answer about the universe. It removes all other questions such as who or what was the creator...how old is the universe...where does it end etc...
In another word, if the universe is not eternal, and finite, you must face the question of a beginning, a creator.
Simple logical questions will start to contradict each other in the existence of infinity. Like Can you count to infinity? what is infinity minus 1? Therefore a finite universe is far more likely than an infinite one.
@@MichaelZMD Just because you can phrase a question such as "what is infinity - 1" does not mean it is a valid question that has a valid answer. It certainly does not support your conclusion that the universe is finite.
@@RobDeManc and How did you came to that conclusion?
@@MichaelZMD Infinity is unmeasurable so asking what infinity - 1 is would be meaningless.
@@RobDeManc You are actually making a good case for the impossibility of infinity. It shows that infinity is just a concept for us to cope on large numbers. And if infinity is a real quantity within the universe, it must obey the same rule as other quantities. such as 10-(10-1)=1. But ∞+(∞-1)=∞, which does not correlate with the reality within this universe at all. The only explanation is that ∞ is a concept, not real.
It seems to me that every point of observation - that which observes the observable - is itself a priori infinite. Infinity is a tacit quality of observation... of conception... of deduction. The very act of observation confirms - or at the very least implies - infinity. Only the observable is finite. Only materiality is finite - the measurable - that which we portray as space & time... whilst observationality transcends all that is finite.
Genuine science confirms you are correct..

I love the hypothesis that we exist in a black hole. And that there are tens of millions of black holes we can see. It’s conceivable there are tens of millions more black holes outside of ours. It also answers why we can never escape our universe. It gives us boundaries but also makes reality infinite at the same time.
Excellent. To assume the observable universe is the whole thing just perpetuates the history of wrongly assuming we are at the center of everything-- going back to the belief that the sun revolved around the earth. Each time, we learn we are wrong and the extent of the universe keeps expanding. Infinite or finite? Can our minds comprehend either possibility??

When people talk of the universe, they always seem to be talking about the visible universe, you know - all the "stuff", the debris from the big bang. What interests me is all the blackness, the "black void" that all that "stuff" (galaxies, cosmic dust etc) is expanding into. Has that black void always been there? Does it just go on for Infinity? Is there a point where it ends and you punch through to a parallel universe? It's all so strange. I don't think science has an answer for this.

You can infinitely divide remaining piece of something by two as infinity and you can infinitely divide remaining pieces in two as infinite infinities within infinite. There is a philosophical infinite and a scientific infinite. Scientifically based on our math, nothing can be infinite so the million years won’t change anything. But human life can be infinite in the mind of a fruit fly. If that fruit fly became intelligent in the next million years, it could look at our lifespan like how we understand the lifespan of the stars. We will never find Scientific infinity in a number, but in a concept, that we can circle a globe for infinite number of times.
@gooberboots We are all different, some can't think beyond their church, other dream with exploring and knowing everything our amazing universe has to offer.
That just completely boggles my mind.
If the universe once had the width of a planck length, and then expanded into a grain of sand and then into an orange, size-wize, how could it after a mere 13 billion years have become infinitely large, or how could it ever grow from finite to infinite? The universe is not a divirgent series, or if it were, it would still be finite as long as it wasn't infinitly old.
Thank you for being smarter than the propaganda.
I think it's more meaning can it expand forever.
You are conflating space and the universe….. these are 2 different things…. Space is finite, as you could reach the end of it before it expands further if you had the technology to fly faster than the speed of light within the UNIVERSE we live in….. and the universe consists of space, matter, and everything else that is beyond that…. As we still don’t know what it is beyond space itself, which is why we named it dark energy… so dark energy is actually the never ending substance or concept that we know and love as infinity, it is truly the only infinite “thing” we know about, and guessing what is beyond that is borderline insanity, as even if there was something else, it too would be endless and so forth.
@@pdj2995 Your notions of universe, space and dark energy seem to me somewhat unusual. Etymologically "universum" means "every thing turned into (versum) one thing (uni)". In modern cosmology everything is understood as being contained in space, and when the universe expands, it is actually space that expands with the things it contains. The expansion of space is not subject to the lightspeed limit, thus two things can, in virtue of being in space, have a relative motion faster than the speed of light.
The notion of dark energy was introduced to "explain" the observed accelerated expansion of the universe. By general relativity alone, the initial expansion referred to as the Big Bang should have slowed down, but as the expansion of the universe was observed to be accelerating, Dark Energy was the name given to whatever causes the acceleration.

is it possible that the "inflation" we "know about" was actually the first sentient being looking up into the sky and forcing the "wave" universe to move to a state where everything had to "settle" because it was observed? Sorry not using the right terms I know. What I mean is, like quantum physics where nothing is "set" until observed.
I hear what your saying, and I like where your head is at..... very interesting...
No, in quantum physics "observation" is just interaction with an outside system. Sentience is not required.
This is a conflation of the meaning of the word "observed". Observation is probably better termed as an interaction between wave functions that causes the wave to collapse. Sentience has nothing to do with it.
No.
Brian Cox is a great science educator. It still blows my mind, though, that so many scientists refuse to believe in God. The universe is perfectly designed for life, yet these people simply won’t acknowledge a creator. Instead, they rely on untestable, in my opinion, things like a incredibly huge universe, that sweeps way beyond the cosmic horizon to explain the universes flatness, 10 to the 500th universes or whatever, to explain the fine tuning, etc. Don’t forget, if you find a watch on a beach, it implies a watchmaker.

Our universe could be like that but just scaled up a dimension. We maybe have to look harder in 3 dimensions to see it's actually 4 dimensional.

Think about it: if there was an actual "beginning" what was here before that? It's the most mindblowing concept you can conceive of: to not have anything: no space, no time, no matter. But it's obvious there couldn't have been a beginning even if there was a big bang because that implies linear time which is really a subjective human perception. You can't have a beginning if there is no time. And how could it be finite? That would mean something outside the finite universe: but whatever that would be would be part of the universe. Therefore it's infinite. Unless you define the universe as just THIS universe and if it has a "boundary" what's on the other side of it. But that's using the concept of space-time and human perception of it. The reason for existence is nothingness is too scary for "God" so therefore there is something rather than nothing. Now what happens when we die? Reincarnation? And if so could we be reincarnated in a different galaxy? That's where Alan Watts comes in.

That's not how light works
The universe : the more you read the less you know.
Quick question. If the observable Universe began from a singularity, is 13.8 billion years old and nothing travels faster than the speed of light, how can the Universe have a radius of 46 billion light years?
It was expanding faster than the speed of light. Nothing now can travel faster that we know about
Nothing "in" the universe can travel faster than the speed of light. But the furthest parts of the universe or space itself that we can observe and measure are moving away much faster than the speed of light. And accelerating.
Because the universe expands from each point in space in all directions and at a great enough distance the sum of all this expansion does actually exceed the speed of light.
When the universe first “popped” into existence approximately 13.75 billion years ago, spacetime itself began expanding at speeds faster than the speed of light. This period, called inflation, is integral in explaining much more than the universe's size.
"nothing can travel through space time faster than light. But space time does whatever the heck it wants"
- Lawrence M. Krauss
The universe must be infinite, there’s no question about it. Our Galaxy is nothing more than a spark rising from a campfire, but something had to exist to start the fire.
I love the fact we just assume there is dark matter there, and not that the universe and speed of light isn't so constant.

But half of it is just made up to fit some mathematical model because there was some hole to a story they can't explain without it.
Truth is we can't even imagine the true nature of reality and the extra dimensions. All we know how to do is put some numbers into an old equation so it works.
@@ObiWanCannabi 100% right, but we can only look with the intellect and technology we have, theories always start with "what happens if we do/add this"
It you create a model and (for instance) add value to account for dark matter and whenever you run that model the results look good it's legitimate to look for something to match your hypothesis, hopefully you will find it.
The Higgs particle was theorized long before it was found. I'm hoping neutrinos are the answer, they're my favourite subatomic particle (you haven't got a fave...sort yourself out) because they're all left handed, which probably means Paul Reed Smith hates them 😉
It often amazes me to think about the fact that the universe is actually only 13.8 billion years old. I mean, the number itself is not that big at all. A modern CPU can already have that many transistors on it, for example. It's a vanishingly small number, really, even when compared to, say, the number of atoms in a grain of sand, which is at least a few quintillion.
Imagine the universe is just 3 sun years old. it's just so young and our galaxy is one of the youngest galaxies. I think Sir Roger Penrose is right. The universe has always existed and it's expanding forever thus it's probably infinite.
What if our universe was inside a blackhole. Meaning our universe was created when a black hole was born. And all blackholes in our universe are other universes. There are quintillions of them.
@@Rikimkigsck but if its expanding, doesnt it have to be expanding from, and to a point? meaning its not infinite, i dunno though lol im no scientist, or is it only "infinite" because were are tied down by the rules of physics?
@@suspect794 why does something expanding have to have a begin/end? The “expanding” is our way of explaining it but that may not be the full story. Im interjecting because, no offense, you have “doesn’t it have to….”…..i dont think it has to.
@@viasevenvai fair enough man lol was just a stoner who's curious about the universe
It's much more difficult to imagine a finite universe than an infinite one in my opinion.
Not really. If a being like God exists and it is eternal then it could have given it all a beginning.
@@madelynhernandez7453 A finite universe actually doesn't make any sense. If you say it ends at some point, it only ends because something else begins, which again means there's more stuff outside of its boundary, and if there's more stuff then it's is a direct contradiction to a finite universe.
@@spbalance finally someone making my point. God, its incredible how many people just stop thinking after saying "there is nothing behind it" like wth? Nothingness is also something, in order for something to "end" there should be the beginning of something else behind it. Like saying there is nothing behind the walls of my house.
Y'all who are endlessly fascinated by this are my people
yes. If there are at least two points in space, one can always in either direction, smaller or larger, go beyond the previous measurement. Time is a function of space, it is a measure of space, so therefore one can (if technologically possible) always measure smaller or larger.
yes.
the universe is eternal.
it's always been there, in some form or another.
Yes my friend and i thingkh like you...And i want to know how the u infinite is the notcreational and eternal in the same time?Who creted the infinite eternal's self who is the notcreational and eternal infinite natural perfection?😇😇😇
Insane to think about, the universe couldve been here before it ended then the big bang started it again, like a cycle
I think thats a kind of infinite regress. If there is no start point then this universe that we live in wouldn't be here
Regarding the size of the Universe, here's a theory I heard:
When the Big Bang happened, and shortly afterwards, the 'energy', photons, whatever that expanded out started transforming into the matter that would eventually become galaxies, and, eventually, some components would become the Milky Way, the Sun and Earth etc.
At the same time, light was also escaping/going away from the Big Bang at, you guessed it, the speed of light.
Forward to present day Earth.
When we look towards the Big Bang through our telescopes, one can argue that we are using / seeing light that has taken billions of years to reach us.
BUT
The original light of the original Big Bang, when Earth, and pretty much everything else, was barely an amount of photons or energy, passed us by millennia ago.
So, it could be argued, are we looking at The Original Big Bang? Or 'just at a really really big explosion that occured billions of years ago, in an even larger Universe?
Did we just come from a Big Bang within an even bigger Universe?
Just an idea.
Nice thought
Thanks so much for posting.
I never found the end of it…and never met a Being that has. After awhile…you get tired of wandering around and you call a place…Home. Some just have…a larger view of home than others. For some…it’s a house. A town. A city. A planet…
so theoretically, the universe would only be "infinite" to us who are bound by the laws of physics, but, if there are such things in existence, wouldnt the universe become "finite" for beings who are not bound by the laws of physics? IE if you could travel faster than light, you could theoretically go to the very edge of the expanding universe. I dunno, i need to stop smoking pot and watching these videos at the same time lmao
Yeah I know what you mean buddy. I got some magic mushrooms as well, Liberty Caps, I might eat some and contimplate this video.
Yep, stop smoking pot.
according to modern theories, the universe is expanding faster than the speed of light.
@@Rowsdower85 Theories are just that, theories. Not fact.
@@sillybilly1662 I understand. That's why I said theory and not fact.
If universe cools down to absolute zero and time stops, all measurements become infinite including distance and time
Time is just a measurement of change, no time just means no change. Therefore the cool down would not make anything infinite
@@hillypk2939 “time is just measurement of change.” I imagine you’ll wait “forever” to collect your data infinitely till eternity
Hillypk2… I appreciate your Short but precise answer… you know what I don’t appreciate? Creatures like CD, who put a bunch of scientific sounding words together in the hopes they make sense, and when they get 5 likes on it from like minded simpletons, they let this minuscule fame get to their head so much, that when someone just clearly corrects their understanding, they get offended and answer back with a snide comment and no actual substance to the knowledge you have provided, not even a shred of interest to understand something better So he could get smarter himself…so I suggest you ignore any other attempts at trying to enlighten this ape with wisdom. As You will now find that it will quickly turn into an ego war, of who is right/wrong and who gets more like ratios. Just move on, not worth it…
@@pdj2995 I’m sorry, I didn’t read your deconstructive quilt of massacred words to no end. You don’t know jack about CD and nothing about creativity. I’ll stop judging you right now short of how you judged me. Your type forces people to be judgmental. That is your contribution to civilized existence. Somebody had to do it. Someone tactless. I’ll stop now. Peace
Saying you didn’t read it yet answering it directly doesn’t look good for you does it? You clearly did, and instead of thinking of something smart/witty/interesting… you decide to prove my initial point correct and proceeded to go into personal attacks without any actual substance to the subject itself… truly a creature with low IQ.. peace to you too buddy.. xx MWAH XXX
I nominate Brian Cox as the next Dr Who.
Absolutely humbling.
Long time ago we think that earth is infinite..but now we know the size of earth. There is a chance that today we think universe is infinete, but iin the future we know it isn't
Absolutely fascinating, and with those sort of numbers as Brian quoted it's easy to see why people are troubled, by where we live and what else could there be beside us?
