Reply #1: Think about a moth around a porch light

[Warpy]

Then think about a whole bunch of moths. They don't collide and they don't go in predictable movements, either. That's sort of like how electrons "orbit" the nucleus, like moths around a light. Were you to be able to see this with a super powerful microscope, it would look like a fog around the nucleus, not a bunch of tidy little points of "stuff" orbiting a tidy little center of "other stuff."
