A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia

Not that I’m an expert on these things but don’t we have a limit on smallness, the Planck length, but not necessarily any limit on how far apart two objects can be? Things moving away via the expansion of spacetime would be able to continue unbounded, but shrinking not so - not without the laws of physics becoming meaningless.
You can still say that spacetime expanding is the same as us shrinking but then you’re just into semantics and sure, you can call things whatever you like.
I don't know I'm just entertaining the idea.
