Then there’s String Theory’s take, that we exist on a three dimensional plane inside of a larger nine-dimensional universe, wherein other three dimensional “membranes” (universes) could exist.

In universes with a fisheye geometry known as anti-de Sitter space, string theory has been shown to provide the only consistent way to reconcile gravity and quantum mechanics.
