> I've been sitting on this idea for a while, and I wanted to see what other people thought about it.

We know that space is constantly expanding in every direction. We also know that the universe contains reality itself, along with time and space. Then, technically, wouldn't time and space be expanding as well? If it is, then reality would be expanding infinitely along with time and space, creating alternate universes and realities in its wake. 

This made sense in my autistic brain, and I just wanted to see if it made sense to anyone else.
