Many worlds theory

[ScruU2wice]

I, with very little knowledge I might, thought that the many worlds theory meant that we were just in a universe in an atom in the toenail of some guy in a bigger universe.

It really seems stupid and logical at the same time to me becuase there can be matter so minute that we cannot measure it. And it can rearrange itself without us being able to account for it. Then I think about it and the whole idea of there being infinite number of worlds contained with in another just kinda seems like a childishly assenine way of thinking
