A finite universe doesn't require infinity to describe motion. Think of it like pixels in a video game. It doesn't make sense to say that there are an infinite amount of pixels between two pixels, because you know there are a finite amount of pixels on your screen (1920x1080 for example). Oct 28, 2021 · We can label the infinite number of universes in the multiverse as universe #1, #2, #3, etc. Because they can be counted, this infinity is said to be countably infinite. This looks to be the smallest infinity. (“Smallest infinity” sounds like an oxymoron but isn’t.) And, no, true infinity is not the same as the symbol ∞.

Some unknown form of energy—physicists call it dark energy simply for lack of a more descriptive Oct 14, 2017 · 45. I often hear it said that, given an infinite universe, all possibilities occur. No matter how unlikely a configuration of matter will be, no matter how outrageous an event may seem, it is certain to occur given the right amount of space. If an eternity were to pass us by, we can be certain that everything that can happen will certainly Nov 6, 2015 · Keeping in mind that space isn’t technically empty, here are some fun factoids about empty space, the universe, and you: If you took the empty space out of a human they would be about the size of a grain of salt.
