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

Finding new videos with Brian Cox's name on them is joy...

[juantkastellar]

I have waited 13.75 billion years to see this video.

[BeatlesFan]

Our brains are not sculpted to understand what this universe is.

[holly.fickle]

I’m a simple woman.. I see Brian Cox, I click.

[mortimersnerd]

Absolutly the best, content to listen to when I need to fall asleep.

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.

[anthonyltllkyser]

There was no start and no ending. This been going on for eternity it keeps repeating! We just evolved this time around.

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!

[PlanetXMysteries-pjnm]

Very impressed with this video. I have always been interested in astronomy and physics. It was things like this that drove me to enter those professions. Thank you for feeding my insatiable curiosity about the universe and the wonders that we discove

[CyphroHll]

With new discoverys, is it possible that there wasn't a big bang but a collision of two dimensions (one over full and one empty. Leaving one rapidly bleeding into the other? Giving the look of as if it was an explosion?

[attilaenergyracer]

This was very well written, and executed. Thank you.

[Z-bone]

What created the infinitesimal point that held all the matter in the universe? 🤯

[samtheweebo]

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.

[jeffwhite]

Had a meal of baked beans & fosters beer some time ago ; that was my big bang ...
Thought provoking video & thanks for that .

[pikiwiki]

thank you for an articulate, thoughtful and deliberate presentation of a very difficult topic

[foley]

One of the amazing things to me is that we’re not some sort of separate thing from the universe. We’re not an outside thing observing the universe around us. We are part of it all. So, especially the universe ponders itself. We ponder the universe and we are a little section of it. The universe is something that thinks about itself.
I know that I’m not the first to think of it that way, but I never really hear anybody talk about it. Except by the woo people. But the woo people are correct, about that little part. The rest is, uh, woo.

[teejay]

Cryan Box is a cool dude and always a good listen.

[johntaylor]

Interesting that the James Webb telescope is now challenging all of this and is exposing how much guess work is going into it !!

[williamowen]

Never mind the big bang, how did the singularity - every thing, get there in the first place? Are there any more of these hanging about?

[ianmcdiarmid]

13.75 billion years seems a very short time period when theres all eternity to go at. 2 branes collided? What made the branes?
