According to MIT cosmologist Max Tegmark, there are four levels of parallel universes:
- Level 1: An infinite universe that, by the laws of probability, must contain another copy of Earth somewhere
- Level 2: Other distant regions of space with different physical parameters, but the same basic laws
- Level 3: Other universes where each possibility that can exist does exist, as described by the many worlds interpretation (MWI) of quantum physics
- Level 4: Entirely distinct universes that may not even be connected to ours in any meaningful way and very likely have entirely different fundamental physical laws
