Brian Cox - What Caused The Big Bang?

Brian Cox - What Caused The Big Bang?
Ever pondered the enigma of the universe's inception? Join Brian Cox and Brian Greene in a captivating exploration of the Big Bang's mysteries. This journey takes us 14 billion years back, to a time when all matter and energy were compressed into an infinitesimal point, destined to expand and create the cosmos we know today.
This video delves into the depths of cosmology, challenging the boundaries of our understanding of physics. Discover the nuances of time's creation, the nature of the universe at T equals 0, and the emergence of time and space as we comprehend them. We examine the universe's expansion and cooling, leading to the formation of the first particles and atoms, culminating in the cosmic microwave background radiation - a testament to this colossal event.
But the intrigue deepens. What existed at T equals 0? Was there a 'before' the Big Bang? Our experts analyze theories like quantum fluctuations, where the vacuum of space teems with energy, potentially sparking the Big Bang. The multiverse theory, string theory's branes collision, and cosmic inflation are also scrutinized, offering diverse perspectives on our universe's birth.
This video isn't just about seeking answers but understanding the questions themselves. We shift from asking 'why' to probing 'how' - how conditions aligned for the universe's birth, how physical laws and randomness intertwined to birth our cosmos.
Dive into a universe so dense that it's beyond imagination, where concepts like 'repulsive gravity' challenge our very understanding of cosmic forces. This journey through the Big Bang's aftermath isn't just a scientific exploration; it's an invitation to marvel at the cosmos's vast complexities and mysteries

As Brian pointed out, if time started with our universe, then it makes no sense to ask what happened before that occurrence, and if it doesn’t make sense to ask what happened before that occurrence, it also doesn’t make any sense to ask how it occurred. That’s because the “how” question always implies a temporal element and apparently there was no time before the big bang.

[@TomHendricksMusea]

My Model For The First Events in the Beginning of the Universe. (From left to right) 1. Singularity before the Big Bang was eternal photons. 2. Big Bang was a release of photon energy. 3. Photons through pair conversion, created space time; and both the fundamental particles and first atoms of hydrogen and helium. 4. The universe temperature continued to drop until the annihilation phase when all free electrons (e-) and positrons (e+) not in atoms, began to annihilate and turn into pure energy. 5. This massive universe wide conversion of mass to energy caused the inflation phase. This model suggests my answers to these physics questions. Q. What was the singularity that started the Big Bang? A. Eternal photons outside of space and time. Q. Where did the anti matter go? A. It went into the protons and neutrons. Protons have 2 positrons and one electron. Neutrons have 1 proton and one electron. Q. Why did inflation happen? A. When the temperature fell low enough, free electrons and positrons annihilated in a universal wide explosion of energy that created the inflation period.

[@maximumscrunch]

I am no physicist by any stretch of the imagination, but I love watching this stuff. For all the physicists out there, I have a question. Prior to the Big Bang, were there any "laws of physics"? Were the processes driving the creation of matter controlled by a "physics" that was extant prior to the Big Bang? Are the laws of physics a product of the "matter" formed during the Big Bang (or simultaneously)? If there were no laws of physics prior to the Big Bang, what would this mean? Could the Big Bang have happened spontaneously from nothing as there were no "laws" that made this impossible? My brain goes into melt down just thinking about this stuff!

[@petyrkowalski9887]

I am a physicist and so far as we can work out, the laws of physics as we know them came into being at the moment of the singularity. There were clearly physics involved but the rules as such are unknown.

[@MrPeterprinciple]

As a physicist, can you please explain what possible physics explain cosmic inflation where all matter, energy and the expansion of space was faster than the speed of light. As I recall, in the early 80's the Cosmic Inflation Theory was proposed to fix problems with the Big Bang theory that cosmologists saw in the observable universe. It seems Einstein's Theory of Reality where nothing can travel faster than the speed of light was definitely not part of the physics immediately after the Big Bang. Cosmic inflation lasted for a trillionth of a second. Thanks.

[@richardrejmer8721]

@@MrPeterprincipleNothing with mass can travel THROUGH space faster than the speed of light. That's true. . BUT the 'big bang' was SPACE itself expanding and carrying the matter outwards with it. . . Imagine a ball of dough with raisins in it. . Raisns on the surface and within the dough cannot travel from place to place faster than the limit (let's call that limit 'the speed of light') BUT if the ball of dough expands as it's being cooked, all those raisins are moving away from one another in the dough. . . Each individual raisin is not moving *_through_* the dough, but is being carried along BY the dough as it expands (faster than the speed of light). Another analogy I've seen used is dots on the surface of a partly inflated balloon. Inflate the balloon quickly. . . All the dots rapidly move away from one another. NONE of the dots are moving across the surface of the balloon. . They remain fixed on the rubber exactly where they were, and yet without moving 'through space' (across the surface of the balloon) they are all moving away from one another at an impossible speed. the dots are moving outwards WITH space and not THROUGH space. Does that help explain?

[@jesterlead]

I think a key point often overlooked is this video is only talking about 5% of the total matter and energy in the universe.

Well when you pull two quarks apart it creates two more. If accelerated expansion keeps going in our universe there may be a point where it expands fast enough to pull quarks apart.

Some people then naturally think we have it all wrong, there was no big bang, Einstein and Newton are wrong etc etc ad nauseam. Drivel.

[@captainbryce1]

@@TedToal_TedToalThe narrator said "suddenly expanding in an explosive burst of creation". This is poorly worded (and misguided language) as it gives the wrong impression that there was an explosion. But cosmologists do not define the Big Bang as an explosion at all, only a rapid expansion of space and time. This video is not the best presentation for layman because it uses a lot of confusing language and even contradicts itself a few times. It conflates "theories" with "hypotheses" (which are two different things), it defines cosmic inflation as before the Big Bang, and then later says it came after the Big Bang. And it asserts that the "singularity" model is the primary model used by Big Bang cosmologists today, which is false. It does get a lot of things right, but the presentation is very poor, misleading, at times contradictory, and ultimately confusing. You are correct to be skeptical of the singularity theory because it has largely been debunked by the cosmological community. But your reasons for being skeptical of it makes no sense. If we assume that the universe did in fact originate as a singularity, then an "infinitesimally small point" would have no space because it is "infinitely" small. It would only represent a point of energy absent of all dimension (including space and time). So there would be no "space" in a singularity. Think of it as a negative dimension, existing nowhere in space, like the center of a black hole. The real problem with the singularity theory is that it doesn't allow for as many predictions as cosmic inflation prior to the Big Bang, which means it's superseded as the inferior theory. Under the cosmic inflation model, you never get to a singularity.

My theory is that there was a universe before ours. Like our universe it had black holes, which keep growing and growing, eating everything in its path.

I think our universe formed much like a drop of water from a leaky faucet. Maybe a universe outside of ours, like you described, allowed for "larger" states of matter to exist. A massive amount of matter was possibly compressed by one of these black holes until a critical point was reached, which caused a white hole to burst into our universe, causing the inflation of our universe. Beyond that, I imagine dark matter might be what our universe is expanding into, and instead of rebounding our universe might just continue to disperse. My imagination is vast, lol. I think black holes are punctures in the fabric of our universe due to matter being too "heavy" for our universe to contain.

How was the temperature of the singularity infinitely high? Singularity means when all matter is packed so densely that no particle is even able to move even so slightly. And temperature is the quantity which refers to how fast particles are moving in a thermodynamic system. So singularity should be at absolute zero temperature (-273.15 K). Please discuss 🙏🏻

[@hari4406]

With very high pressures, very minute vibration can translate to very high temperature. If back pressure is removed particle vibration would be big. Absolute zero is not like that. Eg: apply a high pressure with hand and rub it. Contrast that with low pressure rub. High pressure rub needs only a small rub to generate heat. Although work done will be same if time taken is constant to achieve a particular level of temperature.

Something to consider is that running the clock backwards shows everything in the universe moving in the direction of convergence in a singularity, but it could be that all matter was confined to an unimaginable mass with finite and measurable dimensions, like an impossibly massive and bright and hot star but nevertheless with measurable properties. Think of it like if your house is on Main Street at the center of town (the singularity). Well, just because you show up at the grocery store at the edge of town (the modern era) one morning doesn't mean you left your house, maybe you had a sleepover at your friend's house who lives closer to the edge of town than you do. Just because you can point from the grocery store to the center of town doesn't mean all cars that arrive at the grocery store started at the center of town. Now, I'm not saying this is what happened, I'm just saying it's a possibility that is overlooked, and we can be asking the question what caused this mass of matter with some measurable size to exist. Maybe it's a rant of an older universe which collapsed. Maybe quantum field converged at the point and caused each other to generate particles in unfathomable quantities. Overall the big bang is a fascinating field to study.

You have been lied to if you think a massive bang came about for no reason at all from nothing... Cause and effect = science... for there to be a big bang, there must be a being or a force outside of the place where the big bang takes place for the big bang to take place... bombs don't explode on their own, somebody had to trigger the bomb for it to go off...

[@CountrySteaks]

Science has made a tremendous amount of progress in our comprehension of various aspects of reality, even if it's far from completing its journey of understanding everything; if that's even a journey that necessarily has an end per se. The Bible would have to be the biggest cartoon of all time, or at least comic of sorts - making all sorts of claims based no verifiable or testable evidence, and yet is bold enough to profess knowledge of what created no less than everything. To me, there is virtually nothing more absurd than that. (But I understand why so many people like the comforting idea of a sky daddy that supposedly loves them).

[@rodolfovaliati]

I love your content. Could you share where you find those amazing scenes?

[@josandoy]

The answer manifests itself in everything that happens. The universe forces everything to evolve in a spiral shape until the most outward parts are so spread they are forced back to the center that eventually will have stronger force/gravity. When the center is so tight it has no option but to evolve again, the process happens again, and again.

[@skizecraft]

Its just so insane our brains can not comprehend the absolute beginning of literal anything and everything. Its weird to try to think about on the "why?" And "but what about what caused that to cause that to cause that?" The smaller and further back you go

[@teejay6063]

Tom's Theorem: When a black hole ingests everything in it's path, including light, that light and matter isn't "eliminated" from the universe, nor is it a portal to another universe. Black holes create dark matter through this combined "devouring" of light and matter, and spew it out of their centers, fueling the expansion of the universe. A black hole is never "dormant", it doesn't "burp out" energy when it's full, and it's working way harder to produce and emit dark matter than it does to shoot gamma rays. When it does emit gamma rays, it's actually a drop in activity from "dark matter production", at the same time giving us something we can see and analyze in the form of light beams.

[@Vaporrub8]

Well for now we know that our exact makeup, the way we see the world, the way we feel emotion, and the way in which we think; may never happen again. From any point onward everything is on a timer, slowly but gradually fading out just as the universal masses would cool down and become dark. What happens after is any one's guess. But most likely if some how this happens again, may we reach a similar point like this to enjoy and experience like we once did.

[@robinkelly1770]

I just listened to a theory that gravity is caused by the warping of time. If the big bang was caused by negative gravity would this be the warping of negative time? I.e. the end of one univers's deflation causes the inflation of the next universe with the warping of negative time?

[@ericdebord]

For Every action there is an equal and opposite reaction. So. Once a black hole is created it cannot keep crushing forever so once it hits it's most dense then the BH will create "space" and that space force will push up against another black holes space that it's creating. That's why we are seeing everything expanding . Because every super massive black hole in the center of every galaxy is making space and expanding it's influence. Someone needs to send my noble prize because I'm going to quit fixing these things for you for free.

Another concept is that energy density as measured by the impedance of space is what governs what appears to be gravity. This new idea, The Z0 Code, allows for an open universe with no need for a singularity or big bang. This proposes that the development of the universe is ongoing. It explains what the the JWST sees and incorporates the observations of LIGO.

[@bablumiah2062]

The Qur'an has verses that some interpret as references to the Big Bang theory, though this is debated among scholars. The most commonly cited verse is in Surah Al-Anbiya (21:30), which reads: “Do not the unbelievers see that the heavens and the earth were joined together (as one unit of creation), before We clove them asunder? We made from water every living thing. Will they not then believe?” (Qur'an, 21:30)

[@john.carlson23]

My understanding is if I travelled to an area of super-high gravity (like a black hole), and came back to earth, thousands of years would have passed - effectively moving me forward in time. So, if an area of repulsive gravity existed, would that move me backward in time? Are time and gravity linked?

[@IamKlaus007]

The "big bang" theory is designed to explain the "creation" of this universe and everything in it. We literally DON'T KNOW if there even was a "big bang". We don't actually know how big the universe is, nor do we know if it's finite or infinite. We also don't know how old it actually is. It's wonderful to know that our "experts" can get it wrong. As history has shown, theories CAN be incorrect. If a theory is presented as being accurate, rigorous testing needed to have occurred to confirm its validity.

[@manoo422]

We DO know there was a Big Bang, we DO know how big the universe is and we DO know how old it is. we also know the universe is very definitely finite in size. The theory has been rigorously tested and is very robust. It may not be 100% perfectly defined at the moment but nothing else come close to explaining the universe we see today...

[@mikestephens5200]

I agree Klaus. Two different theories on how old the universe is right now. We don't know its boundaries as things are moving apart and we can only see so far. I've read many arguments on why the big bang didn't happen. But humans don't fully understand physics yet and the experts do sometimes get it wrong. We still have a lot to learn. Peace.

Thank you! Love this video! We all have to come to our own conclusions. I've been trying for years to figure out what mine is. I just can't figure out my own conclusion (and probably never will) what started everything, everywhere. In my mind, there has to be a beginning. Even if I believe the multi-verse theory, and our universe is a new bubble from other multi-verse bubbles, how did they start? It's mind boggling to even think about. I also am starting to think this has something to do with interaction and crossover between dimensions but that's pretty edgy stuff, even for me. Then there's the simulation theory which really makes me crazy so I can't even go there; thanks to whoever put that in my head, ugh!
