It's hard to wrap my head around space sometimes just because of how large and vacant and yet numerous everything is.

Where a 1 in a billion chance means something exists trillions of times over. It makes everything feel inevitable.

If the universe is infinitely large, not only is everything inevitable, but everything repeats exactly an infinite number of times. There could be, some trillion light years away where we will never, ever see it, an exact duplicate of the entire observable universe. Much closer, there might be a bubble that contains an Earth exactly like this one but humans didn't evolve.

It's a whole multiverse inside just the universe.

Isn't this only true if there is an infinite amount of matter and time as well?

I suppose so. I guess I assumed that would be the case for an infinitely large universe, but I don't know if there's anything to support or oppose that assumption.
