If the universe is 93 billion light years across, how is it only 14.5 billion years old?

If the speed of light can’t be exceeded?*
*many physicists estimate the size of the universe to be WAY larger than 14.5 billion light years across (46.5 billion light years in all directions)
So did matter travel WAY faster than the speed of light right after the Big Bang? And if it did, as would be necessary - would that matter have traveled back in time?

Because you touch yourself at night.

I have no idea how any of that shite works.

The Universe is expanding faster than the speed of light.
(Galaxies aren't expanding at the speed of light, for instance. The fabric of space itself is and that CAN travel faster than the speed of light. If you want to get deeper than that it gets extremely technical)

Fuzzy math. The same way Buydem stole 74 millions votes.

This is what I don’t understand amd it makes me feel stupid trying to think in those terms because I simply don’t get it.
What’s it extending into? What’s in the area now that the universe will be in tomorrow?

Universe is expanding faster than the speed of light. Also expanding in opposite directions even at the speed of light it would be twice as vast as old

Do you even Expanding Universe Theory dawg?

You've come to the right place for answers

How is this not matter in some form?

Relax bro, it's just a simulation.

A lot of that is a little over my head, but it isn't expanding into anything, essentially. Space time is 4 dimensional, not 3 dimensional, dealing with curvature and all that.
There's a wiki on it if you want to read it.

Did you graduate from LSU?

This article explains it pretty well and doesn't do it with over technical terms.

It doesn't mean "fabric" in a physical sense but spacetime.
Spacetime doesn't expand with respect to anything outside of itself, so the speed of light as a limit doesn't apply.
That's my basic understanding but I am not a scientist and a lot of it is over my head. I just like that stuff.
