How does dust get everywhere?

Question

You go into a room that hasn’t had folks in it for 10 years and there is dust everywhere. I thought it was skin cells but obviously not.

Even rooms with no access to the outside have dust.

Answer 1

Dust isn’t just some separate substance that enters a room. Dust *is* the room. It’s flakes of paint, skin, frayed carpet, dirt, ect. It’s what happens when the stuff in the room slowly breaks down over time. Dust is entropy.
