Correction: a timeline/quantum branch is superior to a space-time continuum.

Physician and mathematician Max Tegmark defines four types of a multiverse:


 * 1) A multiverse where universes have the same physics on every level, but started under different conditions.
 * 2) A multiverse where universes have the same fundamental physics, but different physical constants.
 * 3) A multiverse where universes represent possible outcomes of actions. This particular multiverse theory is based on quantum mechanics.
 * A multiverse encompassing all possible and impossible worlds.

Type 2 can be modeled to encompass Type 1 within one of the universes it defines. Same with Type 3 and Type 2.

There are, however, two multiverse theories that Tegmark does not articulate, those being brane cosmology and simulation theory.

Brane cosmology posits that our universe of three spatial dimensions is embedded in a "bulk space" of four spatial dimensions. You can, however, have more large extra dimensions beyond this. You could even model infinitely many of such dimensions if you so desired.

Simulation theory posits that our universe is merely a simulation in a higher reality. It's as simple as that.
