I can’t help but wondering about further and further back and the question that’s always asked; why is there anything at all? And this question; Is it possible for there to be nothing? Possible for there to be no universes? Also, possible for whatever brought about the universes to not exist. My brain breaks with the infinite regress.
We have to accept that we will never be able to find the answer about the creator. But we have enough evidence to believe that there is someone outside of all this space and time who created all this. The almighty God.

I am 76 and astronomy has changed so much since then. My dad was one of the original Stony Ridge Observatory members. I went to all the meeting with him over the years while it was being built guided by George Carroll. Since we have had major telescopes in space and especially now our knowledge of reality of what is really going on is incredible and far beyond what was known back then. This certainly made me think again. Thanks. As Steve Morris, of high horsepower engines says, "Danger, Watch this and you might learn something." So glad to learn.
I believe the more we discover about reality, the more we realize how much more there is discover, and how little we know. For every answer provided by the discovery, has produced more questions, than questions answered.

I am always amazed when I learn of nearly incomprehensible Cosmic events like the start of our universe.

What a gift we humans were given so long ago.
It's mind-boggling to say the least, how did the universe even begin? It still had to come from something, and before something was nothing, but before nothing, there's always something

Mate, I reckon that I've got close to being institutionalised, thinking about this stuff. Well, honestly, it could have been spending 26 years with the same woman, but either way, I am amazed at how I ended up at this point.
It's really weird sometimes to be sat at my computer, and be immersed in whatever I'm doing, and suddenly remember space is out there. I mean most things in day to day life you could say are fairly mundane, but space is almost cartoonishly wacky in its immensity and mystery, and its right there in the sky. We should all be going around with our eyes out on stalks over how ridiculous it is, but we just kind of get used to it and it only seems amazing every now and then when we actually think about it. Another funny thing is that most animals don't even know about space, like for example dogs, they don't think much beyond the general area that they're in, and they will never look up at the stars and question what's going on up there. It makes me wonder if we do the same, and we just don't realise it - maybe we just cannot get over the human condition enough to truly understand it, maybe there is something, that to some aliens, is obvious, and we just can't see it. I guess it's possible that AI could break through this, and figure things out that we hadn't considered.
The sad thing is there’s a lot of people who believe they’re here to destroy others, in the insane belief of their superior religion or culture, which tells me they lack the freedom to think, learn, wonder & question with the available knowledge in science & technology. But would they still have those beliefs if astronomy news was an equal part of every culture, like it once was for most? Would todays “woke” activist culture be as focused on being offended by, just about any petty topic, if they looked through a telescope or understood our position in the galaxy & universe? Unfortunately, the more western countries rush to diversify, our empathy is more easily exploited, resulting in less freedom of expression, a fear to question anything, slandering fact as evil, to lower our intelligence for easy compliance. In Australia, our government has failed to explain the fact that Australia Day has nothing, whatsoever, to do with the first arrival, which was April 1770, to explore & mark the transition of Venus in Southern Hemisphere. Jan 26th was chosen as a celebration of the Aussie flag for new & indigenous Aussies, to unite as a new settled country. There was good & bad, as in most beginnings. Life should have a balance to evolve. But there’s no way Australia was going to remain unsettled. Exploration was/is a natural human fact, like unconscious bias is part of every living thing in order to survive & not some problem to be treated.

If something showed up once, then surely the chance for reappearance is greater than the first time.

Accelerating expansion never really seemed confusing to me. If you have regions of space expanding, creating new regions of space that in turn are expanding, rinse and repeat, you would very quickly (in the scope of the age of the universe) end up with an exponentially compounding expansion rate that, while it’s influence on tangible matter might be minimal, the sheer volume of new space and that space expanding would conceivably push things away faster than the speed of light even though the objects themselves are still only moving through the space ahead of them, not the newly created space compounding behind them. They’re not moving faster than the speed of light, new space is being created in between us and them in all places at all times causing the illusion of faster than light travel

To my mind the most interesting question. Are we in a universe that will generate life capable of fully understanding all of its secrets? All we can really conclude just now is that we are trying. But what we do know is that solar systems that are capable of supporting life have a finite life, so perhaps our single most important challenge is to work out how to find and move around such systems.

For 40 years I've been fascinated by the Universe and the question "how can something have no end?". It hurts your brain when you first start wandering and wondering. Many years ago I bought a book called Strange Stories and Amazing Facts and Chapter 1 is titled The Enigma of Space. It says that the universe having an end or going on forever is equally hard for the human mind to grasp. I was determined to grasp it. I watched your video and, highest regard/no offense but you were supposed to give your theory of what was there before the BB and you didn't. I have a theory of my own and I will also dance around THAT WORD. Something cannot come from nothing or have no end unless there was no beginning for it to have an end. There is only one answer. So unscientific and unsolvable. Thank You Sir.

This fits with Roger Penrose’s idea of a cyclical universe, where the universe doesn’t know how big it is once all the matter is gone and time essentially ceases to exist. The idea that it would be expanding exponentially at that point has a nice symmetry with the concepts around the big bang.

If could ask questions it would be.. If the universe is always expanding, where are we? When we detect the background radiation reaching us, are we looking forward in the direction of expansion, or behind, towards the origin? Or everywhere in 24 hours as the Earth turns. Which would also relate to the Earths position as it orbits the Sun. Basically, are we able to look forwards and/or backwards.
Don’t worry about Brian and the Big Bang. They didn’t tell you that the very same Hubble who they say was a big supporter of the Big Bang...wasn’t! Because the record shows that in 1929 Hubble knew “expansion” was not real. Here’s the real story: “Hubble concluded that his observed log N(m) distribution showed a large departure from Euclidean geometry, provided that the effect of redshifts on the apparent magnitudes was calculated as if the redshifts were due to a real expansion. A different correction is required if no motion exists, the redshifts then being due to an unknown cause. Hubble believed that his count data gave a more reasonable result concerning spatial curvature if the redshift correction was made assuming no recession. To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansion exists, and therefore that the redshift "represents a hitherto unrecognized principle of nature". This viewpoint is emphasized (a) in The Realm of the Nebulae, (b) in his reply (Hubble 1937a) to the criticisms of the 1936 papers by Eddington and by McVittie, and (c) in his 1937 Rhodes Lectures published as The Observational Approach to Cosmology (Hubble 1937b). It also persists in his last published scientific paper which is an account of his Darwin Lecture (Hubble 1953).”
If you love watching augmented reality and a bunch computer generated images, you should really watch stuff like "Interstellar" and the movie "Gravity".
Attempting to contemplate the origins of our universe is a supreme though experiment. Trying to conceptualize it may just be beyond our mental capability, (for the moment).
Great vid! I have questions... We are constrained by certain limitations in our universe, such as the speed of light, at app. 300K km/s. As Brian pointed out, the inflation period lasted a mere fraction of a second, expanding from the size of an atom to the present observable universe. I am pretty sure that would be many times the speed of light... Perhaps that was because the forces in this universe weren't fully installed yet at that point in time? And that leads to more questions, such as why do the forces of nature have the properties/constraints they have, and why/how could they be different in another universe?

Sometimes they demonstrate gravity with a heavy ball, like a bowling ball, on a rubber membrane. Then a lighter ball, like a tennis ball, is placed on the membrane and when looking down from above the balls will behave as if they had gravitational attraction. We've all seen that, right? Now imagine there is a fluid under the membrane, something that cannot change volume. The bowling ball will push the membrane down locally, but further away it will push the membrane up. Maybe dark energy, the accelerating expansion, is caused by a similar mechanism.

Fascinating. I remember reading a book about COBE (1989 to the 90's) some 25 years ago and the struggle to achieve the low temperature (near 0 kelvin) to measure the cosmic background radiation. It was an interesting read as it was quite technical in nature, worth checking out.
CMBR: (Cosmic Microwave Background Radiation): Consider the following: Per QED (Quantum Electro Dynamics, whereby 'em' interacts with the electrons in atoms and molecules) and QCD (Quantum Chromo Dynamics, whereby 'em' interacts with the nucleus of atoms), matter has to exist for 'em' to be given off by that matter. What matter exists in outer space for that microwave 'em' to be seen by us? And 'if' it were from when matter first came into existence during the fairy tale of the 'singular big bang', that 'em' should be long gone by now and should not even be able to be seen by us.
Common sense says if there was a big bang and everything was blown out from it then there must be a massive space left in the universe? Why hasn't that been found?🤔
I feel like when people say "this universe has perfect conditions for us to exist" they take the human centric point of view. When in fact, universe is an independent "being". It wasn't ment for us, we just came along as a byproduct. There could, and maybe there are, other life forms that originated from totally different particles that we are not even aware of yet.
I always wondered if there are multiple universes, that would be in different dimensions, would it be possible that some of these parallel universes overlap in some quantum level and if they did; would we perceive that? What if those merging universes, which might be made of different matter, or antimatter in a slightly different time lead to us in our universe to see signs of that other antimatter, or any other universe show itself in a manner we can’t comprehend? It was just a thought.

At least cosmologists now acknowledge that they haven’t got any of the answers other than measuring what we can measure today. It is absolutely the right thing to do to keep looking at both the large and the small, always fascinating and one day it will fall into place, it must be deterministic and therefore will most likely arise from new discoveries in particle physics.
Mr. Brian Fox could never know for sure , there was any Big bang at all. However, it does not matter to him, when he even wants to tell to everyone what was befor the Big bang.... I have a feeling, it is too much to swallow , or he is doing this to promote his income instead of serious science.
As someone who believes in a Creator, I love this kind of stuff (just how vast everything is). Whether one believes in a Creator or not, it's still a mind-boggling thing to ask when just space came into existence. In other words, science can't explain how space alone existed into eternity back.
@@shayneedwards8018 Everything you perceive as the 3D world is the "reflection" of an event of the universe on a distorting "mirror" that your brain and physiology creates. That mirror in mathematics is called Minkowski space and those reflections are called isomorphs. According to relativity, the universe is at least four-dimensional and it cannot be divided in smaller pieces. If you falsely divide it, you get a result that has nothing in common with the original universe. That's why in the observable universe everything seems to be 3D, but as you observe closer and closer to the cosmic horizon the universe becomes 4D and the "traditional" laws of physics stop working. The same thing happens as you try to observe deeper and deeper into what we call matter. In that sense, one could argue that we live in the matrix. We are the distorted reflection of the universe.
In my opinion, when scientists suggest they've realised the extent of the universe, it will, in fact, be at least double what they thought it was, always.

I’ve thought about the paradox of nothing and the idea of infinite regression. Is it possible it has always been and will always be and our focus should be on human psychology and why we can’t accept that not everything requires a beginning. We desperately want to find answers to something that may not have an answer we couldn’t possibly even comprehend.
But "before" is a function of time, which is a function of spacetime which began at the big bang. There was no time before the big bang so there was no 'before'.

The concept of beginning or end are ultimately objects of our perception, they are mere conventions derived from it. There is no beginning, nor there is an end. There is. Same as when you try to think of the most fundamental unit of something, everything is made of something. There is a universe in everything.
My theory is that everything exists because we observe it; things only exist after they're observed, so perhaps everything is in a quantum state before being observed.
I try and engage people in conversation about this subject and it seems most people don't seem to want to be bothered by it. Why? I have tried to explain a light year and get no interest at all.

If space is empty and nothingness…. Then it’s isn’t traveling at all. Are you referring to dark matter, quarks, or something related to quantum physics and string theories?
@@paulc1173 Yes, light observed that has travelled for over 13 billion years from the objects that emitted the light, I hadn't thought of those objects travelling faster than light with the expansion of the universe.
I am not a physicist, but I think that moving particles, vibrations of the atoms is what we call a time. If these particles would not move (an absolute zero) - time wouldn't exist, there would be just empty space.
In the beginning there was nothing, which exploded. But the James Webb telescope has found six massive galaxies beyond ours which upends the bang theory or at least pushes it back way beyond the point at which we thought it happened. These galaxies were found at a point in time when the universe only 3% of its current age and are far larger and mature compared to what they were expecting to find which would have been baby galaxies. Further spectrum tests are being done to confirm these findings.
If there was nothing in the beginning than how could an explosion happen? Or (Big Bang)Who put the ingredients together for the explosion 🤔😄 seriously! Who comes up with this nonsense. It makes more sense to even believe in an eternal God then that silly theory.
It's a good theory given our current knowledge capabilities. I also like to ponder what the "big bang" is in. What is the space beyond "space", in which our universe is expanding? What happens when the universe stops expanding, does it collapse and expand again over and over?
It’s like space but a higher dimensionally version. It also has like but higher time, a flow of higher light through higher crystal whose refraction created all we know here
Space expands into itself. There's no beyond space. Imagine this analogy. Instead of the space expanding, everything is shrinking. You can have your space, but for everything inside that space it looks like there's more and more space everytime and things are further and further away. The space has "grown" on itself.
There is no space beyond space that we can observe and may never be able to. Think of a balloon that has no air but then you start to inflate then it stretches. That is what is happening to spacetime according to current theories.
@@burnerburner4074 Its laughable. Why not listen to a guy thats 1000 times smarter than this Brian Cox guy and his fluff videos? go to the "LPPFusion" channel and learn some REAL TRUTH!
Saying everything was condensed smaller than atom at the begining is confusing because theres no way to measure it with nothing to compare it to. Are time and space the same now as then?
I always give myself a question. Where did that extremely dense, hot and full of mass, tiny matter come from? How it possibly might locate in anywhere if there was no spacetime at that period? How can i accept the Big Bang theory if it does not give any explaination to its fundamental aspects like this?
Spot on. INFINITY is the answer. No beginning, no end. Time doesn't exist. Everything is essentially now. Past Present Future all one together. Consciousness INFINITE. Universe INFINITE. Makes sense when you think about it.
The question of what caused all this to happen always gives me immense anxiety and I have to force myself to get over it, cope and move off the topic.. If the big bang caused all this to happen after it started, what was there before the big bang? What caused this to happen and what caused all this to exist... Sometimes I like to imagine that one day we'll be able to understand things in such a deep way that'll answer this question that we can't even comprehend right now. I can't even wrap my brain around what could have caused all this to pop into existence. That's why I could never fully believe in religion. Some dude just popped into existence and created everything... Just thinking about this makes my brain want to shut down
I think I shared the anxiety you felt but I have now replaced that with awe and comfort because now I believe in a benevolent creator. The older I get the more I see free will amongst the forces of good and evil, love and choose wisely, as though your actions matter. I believe the creator or even creators of our universe (perhaps the creators have a creator, we will never know) are benevolent, that everything could cease to exist in a moment however that has not happened. Instead of fear think about love and hope
@@brendansherlock6442 Great sense of benevolence. Maybe this creator can explain why it allowed people like Hitler to flourish. I'll NEVER be convinced of the existence of a benevolent anything. The religitards can cling to it if it gives them comfort.
There is no way that at some point space and time don’t exit. If physics didn’t exist in the past then what did. So there was magical stuff and suddenly science was created. There can’t be any possibility for the idea that the physics system we live in has a beginning and ending.

No such thing as "nothing" though. Despite it being a logical and verbal phallacy - i.e. if you can describe it with any of the parameters (height, width, depth,) since it occupies a certain space, it's not "nothing" anymore. Even the ancient Greeks knew it. Nothing can't be defined in any way possible, once you start describing it, you're describing something that has certain parameters, whatever those are. So, despite that - it has been proven (and people won Nobel's for it) that there's no such thing as "nothing" in the Universe. If you take the empty space, billions of light years away from any other object, get rid of all the dust and radiation particles, and all of the atoms, photons and such - it's still something: boiling soup of quantum fluctuations, subatomic particles popping in and out of existence, and most importantly it can be weighed, and it has a certain energy. No such thing as "nothing"
@@loopmantra8314 To my mind, the only thing that can existe as nothing, is space itself. And here, I mean technical space, as complete vacuum, because I know that in reality, space is filled up with particles. But the thing is, even if real space as vacuum doesnt exist, if we take a bottle of water, when it's empty, it contains a certain volume of space, and once it's filled up with water, there is no more space left. So, in this analogy, while space is gone, its notion is still present, otherwise, the water wouldn't have had the room in the bottle to occupy the exact same volume as the space did. So, space doesn't exist only because objects are occupying it, not because of actual impossibility. Now, I don't know whether there is such a thing as complete empty space somewhere, maybe outside of the universe if it's not infinite, or maybe between other universes in the case of multiverse. However, according to the Big Bang theory, before the birth of the universe, there was no space, which means the universe is expanding into nothingness. And since this "nothing" doesn't provide any resistance to the expansion of the universe and isn't made up of actual space that contains subatomic particles, then this "nothing" must just be real empty space. In that case, something, aka such space, can exist without having any parameter. So, only space can possibly be an exception and exist as "nothing", and provide a container for other things to exist within itsef. And each of these things must have parameters like height, width and depth in order to be physically described.
As a species, we have come a long way in discovering more and more about universe and the ability of different humans to ponder about what was before big bang and thinking about infinite and parallel universe and the size of universe is just like imagining earth on our tiny little finger in comparison to size of our room or our home....so each theory would vary differently as different sizes of each of our homes 😉
Well. You’re assuming that there has to be a before… the universe or existence or matter… it doesn’t owe us or itself an explanation. What if things just are? What if physics just work the way they do on certain variables? What if there doesn’t have to be an end or beginning? What if it always was? What if it is beginning and ending and that’s it and no explanation. Just is? I think some things we cannot fathoms. I mean.. all we can do is perceive in the 3rd dimension…
Not a spiritual person, but the Hindus (?) say something to the effect that after death all will be clear. Maybe the answers are very simple but we are simply not allowed to know the answers on Earth. Crazy? Maybe, but no less nuts than saying the universe came from nothing on its own.
I cannot fathom how something transforms from finite to infinite. Further, I cannot imagine how something that is infinite can grow. Perhaps I misunderstand the term "infinite." Perhaps it doesn't mean something without end or limits, but rather something with unreachable or unbreachable ends or limits, like the infinity's sign of the sideways 8 suggests, two loops that are limited but without end.
"twice as big" probably isn't the most precisely accurate wording. Nor is "infinitely small". We actually can't say for sure there was an infinitely small singularity at the beginning, just that generally smooth temperature of the CMB indicates that it was very, very, very small.
@@drsatan9617 I didn't say singularity. It would make no sense to attempt to differentiate size for a singularity. Singularities have a radius of zero by definition. I was talking about an upper bound to the size of the region of the universe observable via the CMB as an indicator that everything would have had to be very, very close together to reach thermal equilibrium before it spread out too far for radiation to equalize the temperature due to constraints on the speed of causation.
It wasn't infinitely small, it was probably infinitely large, the same as it is today. The point was that a very small region of the early Universe (smaller than an atom) doubled in size many, many times within a fraction of a second. And this probably happened everywhere, not just in that region we call the observable universe. We know that the Universe is infinite, and always was, because if it was finite gravity would have made it impossible for it to expand. But being (almost) infinitely dense _everywhere_ there was no centre of gravity to hold it back.
@@drsatan9617 @Dr Satan @Dr Satan I'm using the same definition of singularity that you are, but I was not talking about a singularity. I was talking about very dense, but not infinitely dense early state of the universe. We can trace back all we can observe now was once in a very small region. I'm just not 100% convinced it tracks back to a perfect singularity. I don't deny that it could have. I'm just not sure. I refered to temperature equalizing because the CMB has a generally consistent temperature, and either presuming it started from chaotic random energy fluctuations or a catastrophic collision of branes in a hyperspace, the temperature of the universe would initially been free to have extremely variable temperature when the CMB was emitted, but we do not see extreme variations in the CMB temperature. The alternative being less space and shorter distance for energy to move from more energetic regions to less energetic regions before the average temperature cooled to the point of transparency. Still, a singularity is a point. Points don't have size greater than zero. They have some other value that is infinite, but the size is zero. Singularities may not even physically exist, they might only be mathematical anomalies that indicate we have pushed a model beyond the boundaries of its applicability, so I think ot makes more sense to consider what the models say up to those limits, while taking the infinite value itself at any singularity with a grain of salt.
So why is the Universe EXPANDING from a central Point.. That is what was proved by HAWKING. Nobel Prize and caused recognition of his knowledge. But if your theory is useful then you should Publish your deep knowledge to humanity for the World to use. We can now see into what happened. We are seeing it unfold with light and vision that is only just reaching our eyes after 800 million years. Hard to not believe your own eyes. Unbeliavable stuff, but its on film. 🇦🇺 6:49
That last bit was scary ! How or why can it be expanding and increasing the rate expansion without a reason/ cause? Yeah 😮😮😮😮 There must be a vacuum / suction force pulling it apart. Maybe dark antimatter ? A huge great attractor pulling the Cosmos open ? Like when you put a knotted neck balloon into a container and then apply a vacuum around it, it expands...
I love the visual right at 1:01 I think that's pretty much exactly how the big bang happened. From a singularity to unimaginable expansion just that fast.
The universe is too vast for us to comprehend. Try as we might we are so insignificant and there is no way of every establishing where the universe began. There’s a chance it has always existed, but human nature always has to assert a start and an end point, it’s beyond our understanding we can only theorise.
I don't know why people can't accomodate this line of thinking. Everyone buries their heads under the sand and are not open to possibilities of a "before" to the big bang just because they've rote learned some assumptions which can be subject change.
I believe in the KISS Principle. Using Einstein's Theory which has yet to be disproved, to get the "Energy" of a Big Bang, there must have been a "Mass" travelling at the speed of light squared. Now even if there were two masses traveling at that speed that collided, the question that begs is WHERE DID THE MASS OR MASSES come from if there was no universe? Wouldn't a simpler explanation be that there was ALWAYS a Universe and that it just keeps changing over time.
There may have been many big bangs. I see the universe as a sphere, an unimaginable expanse comprising over twice what we can detect. I see the cosmic matter as behaving like plate tectonics, moving over this Sphere measuring billions of years in time. Cataclysmic encounters of masses colliding then sent hurtling through the cosmos to the other "side" and happening again in a seemingly eternal fashion. Energies so massive, big bangs occur.
I Like the idea that the big bang was the moment our region of the universe entered a black hole. The beginning is too hot for atoms and extraordinarily dense. As the black hole expanded everything cooled unpacked and began building again.
When I was in 2nd grade my science book said Venus was blue because it was covered in water. It also had a chapter on crop circles that said the crop circles were caused by wind that would come down and roll out the fields in perfect circles. It had perfect cartoons drawing out the wind rolling down hills and flattening out circles.
Our brain can understand the word "Endless" - something will go on and on and will never end. BUT our brain cannot understand the word "Beginless". Everything has to start sometime, somewhere! The concept of Big Bang comes from this limitation of our brain!
