The 3 ways that parallel Universes could be real
When a quantum interaction happens, one interpretation leads to an infinite number of parallel Universes. Here’s how that could be true.
“As an analogy one can imagine an intelligent amoeba with a good memory. As time progresses the amoeba is constantly splitting, each time the resulting amoebas having the same memories as the parent. Our amoeba hence does not have a life line, but a life tree.” -Hugh Everett
The idea that things exist in a particular, well-defined state at all times where their properties can be determined so long as you can measure them well enough was fundamental to how we conceived of the Universe. When quantum physics came along, that idea went right out the window, never to return. The Universe, at a fundamental level, is indeterminate. One possible interpretation — that of infinite parallel Universes — holds that every time a quantum interaction occurs, all possible outcomes do actually occur somewhere, with only one of them reflecting what happens in our observable Universe. But if the right conditions exist, these parallel Universes will actually be real.
