[donkerbolls]

The idea that there was apparently a timeless nothing before the big bang still completely fucks me up

[redreuben]

I nominate Brian Cox as the next Dr Who

[catharineholton]

He seems to have a permanent smile, even when he is speaking, which certainly helps his presentation.

[antonio]

Brian is a scientist that explains everything so smoothly

[HkFinn]

Wow, that’s one of the fastest expanding universes I’ve ever heard about!

[christiandavies]

I'm beginning to thinks this Big Bang thing is a bit of an understatement.

[bobbymckenzie]

The key words are "what we think don't have a clue

[dasmith]

When I hear these explanations, I cannot help thinking about when scientists declared it would take 50 years to sequence the human genome. And about 5 years later, the job had been done.
The problem is applying processes we know and understand to situations we do not know and understand. And being terribly sure that we are right. 🤔

So...
We measure the age of the universe based on the distance light travels. We have a set velocity for the speed of light, and presume that nothing can travel faster than that speed. So someone calculates how old the universe is based on light years, and yet we are now being told that it all expanded, "stretched" one could say, from an infinitely small particle, into all that we see in a "ridiculous"-ly small amount of time.
In an instant, one could say.
And yet there is still the problem of where did that infinitely "smaller than an atom" particle come from, and from where did the energy which caused it to expand arise?
This particle would have all the gravity of the entire universe packed inside it, thus making it the mother of all black holes.
It would take more energy than all the energy in the universe, then, to overcome the gravitational pull of that mother.

What, then, or Who rather, pulled that trigger?

[ from Isaiah ]


"This is what the Lord says—

your Redeemer, who formed you in the womb:

I am the Lord,

the Maker of all things,

who stretches out the heavens,

who spreads out the earth by myself,

25who foils the signs of false prophets

and makes fools of diviners,

who overthrows the learning of the wise

and turns it into nonsense,

26who carries out the words of his servants

and fulfills the predictions of his messengers, "


[ From Psalms ]

"1Bless the Lord, O my soul.
O Lord my God, you are very great.
You are clothed with honor and majesty,
2 wrapped in light as with a garment.
You stretch out the heavens like a tent, "

[ From Genesis]

"And God said " " Let there be light" ", and there was light..."

Click.
BANG!!

Faster than the speed of light.

[PAULsteki]

My question is, if the universe came from nothing, how long was the nothing and when the nothing became something what happened to change that?

[alebarruel]

¿Why or how do you think that first acceleration inflation it was so fast?

[Ziggyzaggy]

I didn't know Keanu reeves became a scientist

[CP-]

This explains from the point that the match is lit. Before that is the realm of theologians and philosophers.

[ThestDukeDroklar]

Key words are, "they think" that is what happened. There's no good evidence that inflation theory is accurate or that 3D space can inflate. It's all based on the redshift of light and there are other possible explanations for that redshift.

[MrKoffeeKup]

I heard someone once mention that because space and time are so interlinked, its possible that time dilation was in effect here, so instead of galaxies appearing out of nothing in fractions of a moment, it was one long moment drawn out for billions of years because everything was so close together. Relatively to that time everything would have progressed much as it did now, just that our time is now much much slower because of inflation of space time.

[zhangruoran]

He didn’t explain how the universe was created from nothing as the title suggested.

[thespeedracer]

This has to be the MOST counterintuitive, absolute SEEMINGLY impossibility.

To truly comprehend this beyond a very macro level, with even a high-end human brain (so I'm told)...

[haroldkline]

I wonder what the start up of a computer program would look like from within. It might look like it burst into existence faster than anything close to definable.

[Awesome]

So it's expansion was much more faster when you get closer to the beginning and now it's getting slower and slower? At which point will it stop? Or will it at all?

[meao]

cox is so sweet that makes physics cute
