Brian Cox – What Was There Before The Big Bang?
Physicist and professor of particle physics Brian Cox explains hypotheses about the causation of the big bang. Brian Cox is a brilliant scientist who makes complex cosmological concepts like the big bang way more easy to understand.
In the beginning, there was an infinitely dense, tiny ball of matter. Which started to expand and would eventually give rise to the atoms, molecules, stars and galaxies we see today.
But what was there before the big bang? What was the state of the universe before…Well, everything?
Brian Cox explains how inflation fueled by a mysterious form of energy that permeated empty space itself, left the universe desolate and cold. And only after that did the hot, dense conditions of the Big Bang emerge.
If cosmic inflation correctly describes what happened before the Big Bang, it may push the ultimate answer to the question of where we came from beyond the reach of science.
Brian Cox also mentions alternative theories to cosmological inflation which tell us what caused the initial conditions that would eventually give rise to the big bang.
The twin pillars of modern physics are Einstein’s General Relativity and quantum theory.
To understand how the big bang emerged and what came before it, it is essential to unite Einstein’s theory with quantum theory.
The most distant objects in the Universe are 47 billion light years away, making the size of the observable Universe 94 billion light years across.
If you are wondering, how can the observable universe be larger than the time it takes light to travel over the age of the Universe? The answer is because the universe has been expanding during this time.
And this causes very distant objects to be further away from us than their light travel time.
Most scientists think the entirety of the universe extends way beyond the observable universe. But is there anything beyond the entirety of the universe?
Brian Cox also explains if there is anything beyond our known universe and how it will “end”.

Einstein is just 1 scientist out of a billion other scientists. how fast is the universe expanding at?
Always entertaining that boffins talk about lengths of time when there is no way to measure it 14 billion years ago. We still can't define time & we've been workin' at it for millenia.
I came hear for Brian cox. Who the hels talking
That's easy to answer, there is no beginning of time, it started a physical material matter as we know it, the underlining is the spiritual the metaphysical, quantum component,
As a kid I read about shadow reality/dimensions in a Dutch magazine called Kijk (Look). If remember correctly it was when collided nothing would exist (matter + anti matter). This was how the big bang was explained in the 1980's.
We're in a black hole, the other side.
If it wasn't a big enough mind F#ck already…. Maybe if we last a few millenium we will know. Multiverse is probably the easiest, lol, it's gotta happen somewhere, sometime in infinite dimensions/multiverse. Or CMB is a commercial from the program writers
"Here you are humanity, have an infinite galaxy to explore. All to yourselves!' Nice one god! Cheers mate.
Our whole universe is just an atom on a giants thumbnail.
Jennifer Aniston farted out The Big Bang.
Before the big bang? I had to buy her fat a$$ dinner and drinks .😏
There wasn't a Big Bang… so… it's a strawman question… next!
This is the question isn't it and really, no matter how many theories are postulated, no matter how many universes there are, you simply can't get around the fact that something had to initiate the whole thing. How can something have existed forever? What started it? And how do you know they are the oldest lights in the Universe? Do you mean the observable universe? Because if it's only the observable universe, then how much bigger is the rest of the Universe? AAAAAARRRRRRRGHHHHHH!!
Always enjoy Brian's explanations.
The big foreplay.
I have an idea. Before the Big Bang I assume there was no physics or a way to measure or compare the singularity to anything. Once the universe has infinitely expanded such that there are only singular points of mass with no way to measure or compare them, hasn't the universe just collapsed back to its original state?
What physicists like to ignore is that everything had to come from something. Even if it breaks their theories and calculations they have no choice but to accept that whatever form predated the mass and matter it DID exist. So the question is legitimate and cant be tossed aside just because it ruins their pretty theories when they have to include and factor in that form of the matter and mass existed and predated the universe
What was there before time? There cannot be a was before time. The question makes no sense.
Before the big bang there was nothing. However nothing cannot exist. There cannot be nothing because nothing cannot be. Only something can be.
These questions will slowly drive you insane if you dwell on them.
Ahhhh, but what was before that you smart arse? 😁
lots of people in the comments that know what happened as if they were there……
no one is right, it's all wrong & "maybe" we will figure it out one day
Before the "big bang", there was just pure consciousness…quantum physics gets closer every day to linking consciousness to the quantum world
At this point they may aswell just say it came from gods asshole
"I don't know" shouldn't need over 30 minutes of self-indulgent verbosity. But it does if you're narcissistic.
there was smiley 😊
Are the laws of thermodynamics valid and unchanging? If so, then before this Big Bang Started was all the energy there is, that was there forever as its never created. . . . . . . . . . …………………………………………………………………………………………………………..If you have extraordinary outrageous claims that such laws can change then its up to you to post the evidence that proves so as your opinions are not enough to change such fundamental laws… Saying we dont know anything is to lie such laws can change. . . .
I could listen to Brian talk about anything.
The original condition that caused the big bang is God finally decided to create everything .
Once you get past all the planet's, stars and galleries there is absolutely nothing on and on forever .
But the most basic question is, where did Physics come from? The math how did that come into place? You need something for the information/matter to work against. How did that come into place?
Inflation occurred AFTER the big bang in every definition I can find.
The little big no bang.
Correct me if i'm wrong. If we pick a point of light 13.8 billion light years away and could travel at the speed of light. By the time we got to that point of light, it could be another 13.8 billion light years away. And so on and so on. So the the Universe would be infinite.
From 4:48 – Theory of Large Extra Dimensions is by the genius Georgian (Kartvelian) physicist – Gia Dvali.
Im suscribed to you. why is that the first time i seen a video from you in almost 6 months…? Is it you or youtube?
Assuming the Big Bang “theory” is in any way shape or form accurate. It’s still a largely unproven theory.
Bro speak for yourself. I hate these so-called smart people who always talk about "we". We don't know? I know. God is real. That I know. "we" do not exist. You exist at least for a while and I exist. There is no we. You go your way and I go with Jesus. Thats the facts. You could repent and believe on the One who was sent. Or you can die and die in hell.
Of course Brian Cox would know all about it….. because he was there right at the beginning !
The scariest thing is that if u have the ability to move shift transport teleport and expose everything every atoms in this universe and after removing everything, u will still never find out why are we here, and what is outside of us in the grander scales. Seriously why are we here?
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?
What was before the big bang? What there is now, because logically (not something endorsed in modern astronomy) there was no big bang. Total nonsense.
The big bang seem great but God had examples earths what life is at the end then he created the heavens and the earth where someday predestined for earth it won’t end like human space migration to homo sapiens evolution past extinction
LMFAOOOO the fact that these people are in such denial boggles my mind. there is a LOTTTTTT of VERYYYY RATIONAL logic that points to us being in a russian egg doll (matryoshka) of simulated universes. the question of the first or if there can even be a first is different, but there is a HIGH likelihood we are in a simulation (aka a CREATIONIST universe) based on a few VERYYYY CONSERVATIVE assumptions (such as the fact that matter can simulate a universe [see 'imagination' haha] and that the universe is old). any effective betting person should bet on this being a created universe. you'd be throwing money away not to.
a gambling man should bet on this being a created universe
