So, you know, you sort of run physics backwards.
You basically say, you know, this is how the universe is expanding now.
And let's roughly say that, you know, things came together.
And as I mentioned, you mentioned the podcast, the Big Bang did not have a center.
The galaxies are not flying off into space like an explosion.
What happened is the galaxies are all kind of sort of standing where they are, but space itself is expanding in every direction between the galaxies.
It's a hard thing.
It's a huge misconception about the Big Bang, that the Big Bang was this explosion and galaxies are flying into empty space.
The expansion of space is space itself.
There's no space out there that galaxies are flying into.
That's not how it works.
When I used to teach this, I used to take a board and I used to have a piece of elastic and I would hammer two nails in on either side of the board.
And then I would say, okay, these two nails are galaxies.
And the elastic between them represents our universe.
In this case, a two-dimensional depiction of our universe.
All of space and time, anywhere light can travel, is just on that elastic.
Don't think about up or down.
There's no space or time there.
Everything our universe is is just this piece of elastic.
And then I would take the elastic and I would stretch it.
