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

[@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. Hardly worth a video, perhaps, once the smart folks figure out how dark energy / matter interact in all this which are by far the "drivers" of our universe. We just can't see it...

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. More likely that the early universe was super-dense and hot (we know that) with intense dark matter action allowing first-gen galaxies to accrete stars extremely rapidly.

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. Then the expansion energy starts to pour into matter creation. Then gravity adds up and slows expansion down. Bang a bunch of matter and an extreme expansion rate.

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.

[@Sam-lq2jh]

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. Until a time one black hole gets so big that it swallowed everything else in the universe. With that black hole having nothing else to feed it it eventually exploded in a "big bang" and a new universe began.

[@patrickdodge916]

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.

[@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.

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.

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.

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.

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! It all just makes me wish I went into this field, it is so very fascinating! I'm a huge fan of Brian......oh well, back to work.

How can there be nothing. I cant see it, we are educated with a beginning and an end. But how about no beginning and no end

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.

[@micht6888]

I can understand their explanation of the big bang. I've always wondered where the single atom he mentioned came from? What was before and where did it come from?

[@michael-4k4000]

It didn't come from anywhere. It was always there wise guy.....

[@patryk2535]

@@michael-4k4000 "It was always there" is a religious statement (philosophical at best), and has nothing to do with science or understanding the universe.

[@danielbrewer6469]

Look into the Higgs field and boson particles. Also check out "Is nothing something?" I'm not going to pretend I have a mastery of this knowledge, so I'll let you research this on your own. What I can't wrap my head around now is that before the Higgs Field could exist, a *place* had to exist first that would allow the physics of a Higgs Field to exist. (Presumably) A lot had to happen before the singularity. (Also, Presumably) This is where you could venture into an "eternal chaotic inflation". But that would still require a place for this to exist. This is where I am personally. Maybe a real physicist can chime in and tell me how f'd up I am. Lol! Haha

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?

[@Kyedo2022]

So dark energy as an anti gravity is everywhere regular matter/anti matter isn't pushing it both together in clusters and apart as a whole because whenever you have a net charge of some type then there is repulsion kinda thing?

[@timcarpenter8526]

Is it possible that Inflation was able to happen with the speed that it did because at that point space was actually being created and without the prior existence of space there would have been no constraints of time?

[@winkipinky]

See I think inflation theory is all wrong because without time, space or an observer, size meant nothing. Think about it, a circle is still a circle no matter what size it is, and it gets bigger, or smaller the bigger or smaller you, the observer are. Scale is meaningless without perception of time and space.

No.

[@danhnguyen-fn9eb]

The hows and whys of the Universe and it's existence is probably a mystery that we'll probably never know despite of all of the cute little equations that try and fail to do so. But one thing is clear even though they won't admit it. Repulsive gravity = explosion. Inflation = explosion. Unimaginable forces, temperatures and expansion from an unimaginably small and dense object = explosion.

[@jupitermoongauge4055]

Whatever it is we are, we are entities which perceive whatever the universe is in a time based continuum. Perhaps time is a function of consciousness, a way of consciousness gaining some kind of perspective of itself, like the visual images in our minds are constructs of the brain

[@philmason7860]

One explanation is that we caused the 'Big Bang' by having the thought that we could separate from our Source/Oneness/God. The material world/the universe is then an illusion or the dream that we and everything else are separate. This is based on 'A Course in Miracles.'✨✨😊😊✨✨

[@arivenes]

I am wondering, where do you locate the dark matter and dark energy in the Big Bang theory? Did it appear along with our matter or it was existing already? Was there any of dark matter big bang which happened before or after the Big Bang?

[@richardwilliams7225]

Two thoughts...... First ...If time and space were created at the moment of the big bang, then events preceding it are unavailable for observation and are therefore irrelevant. Two...If, at the moment of the big bang, the universe was a singularity with infinite density, the gravitational forces would have been so immense that it would have been impossible for it to explode.

[@Zethuzzz]

Give JWST time and the theory of Big Bang itself maybe in question

[@m.musthafa6865]

James Webb telescope findings had contradicted that no such thing as Bing bang and subsequent inflation had never occurred. But Here you’re explaining Bing bang 🤔

[@maumusa123]

The idea of Big Bang itself is ridiculous. We may never know how the universe started, if it ever started.

[@roberttapper3296]

It's good question to think about, but I think we could have infinite time and still never know the answer. There maybe one way to find the answer and that would be from the A.I singularity, again if it is actually possible to create.

[@danielrayner7681]

Very interesting video. We seem to rely on the concept of inflation but we must remember there is no evidence for it, it is just an assumption we have made to fit our observations

[@WestAirAviation]

What confuses me about "13.8 billion years ago it all started" is that we know time is flexible. A gamma ray created during the big bang could, today, be 1 second old from its reference frame. And we have no reference frame for the Universe itself. We don't know if the observable universe is moving at relativistic speeds compared to a much larger cosmic structure. The observable universe could be like that gamma ray, and 1 second to us is 14 billion years to some other reference frame. How can observable red shift really give us that answer?

[@MrCharlesdick]

Pretty sure it's just the wave function of the universe, like normal. As we collect more data about the relative motion of galactic clusters relative to each other as perceived from our local perspective, developing a best fit model to generate a wave function should be pretty straightforward. No idea why people in general seem to not get this.

[@Pateffs]

Random events.. in all the chaos they might looks like random events when we perceive with our human brains and eyes.. but in the end we know its an cycle that goes and lives thru. Thus making universe/multiverse infinite.

[@rxw5520]

They swiped the tiny bit of Brian cox audio from another video, and used the title as clickbait. If I’m not mistaken it was a video of him answering questions from Australian school children. Really good video. A lot better than this one. And original. The rest of this is Brian Greene.
