multiverse theory
Many worlds hypothesis
Multiverse theory is the hypothesis that our universe is one of many—perhaps infinitely many—universes existing simultaneously.
These parallel universes might have different physical laws, constants, or histories.
The concept appears in physics (arising from quantum mechanics and cosmology) and in fiction, where characters cross between alternate realities: The show explored multiverse theory by having the protagonist meet versions of herself from other timelines.
