Space-time is going faster than that.
And soon after that, we start to have particles forming.
The universe is filled with like this dense plasma of hot particles stew.
And so if you think about it, something trying to move around in a stew, for example, just to take that metaphor, stew is thick.
It's constantly running into like potatoes and chunks of lamb and like pieces of carrot or whatever.
And so in this case, a photon, like a particle of light, it gets emitted, but it can't go very far without running into something.
And so this is like the very early stages.
And then at about 380,000 years after whatever came before,
For the first time, hydrogen atoms start to form and the universe starts to cool off and light can travel freely through the universe for the first time without just constantly running into something.
You might be thinking, this is very detailed.
How could you possibly know that?
And so the incredible thing is, is that this light is still available to us and we can see it.
And we've sent multiple telescopes up to space to measure it.
We have telescopes down in Antarctica that are studying it.
And then you have these hydrogen atoms are gravitationally attracted to each other.
So they start to form clumps of gas and those clumps of gas get bigger and bigger and they start to gravitate more and more.
And in some cases, they condense enough into clumps that will go on to become stars.
And those stars eventually die.
They leave behind gas.
Another generation comes along.
