It's not expanding, separate points are growing further apart.

Any metaphor you hear about a balloon or fabric or things like that is an overly simplified version of complicated mathematical models of the universe.

Long story short, no and that's because forces are only applicable in certain situations and not others, and in this case gravity, electromagnetism, and similar subatomic forces are binding the atoms we know and preventing them from "expanding". I'm not an expert and this is just my simplified version of a simplified version.
