10 Most Compelling Pieces Of Evidence That Prove Alternate Realities Are Real
10. The Many Worlds Theory
All the way back in 1957, the physicist Hugh Everett provided a theory of multiple realities that took in quantum mechanics, suggesting all possible alternate histories and futures are real within their own worlds. It could be a lot more complicated than that, but the version that most will understand is that there are a large - possibly infinite - number of universes, and everything that could possibly have happened in our past occurred in some other reality. The formula was expanded upon and popularised by the many worlds theory of Bryce Seligman DeWitt, and is just one of many multiverse hypotheses in physics and philosophy. It's the best known, however, and the one with the most scientific basis backing it up, built as it is on existing accepted theories. As much as a sci-fi concept as alternate realities are, the many worlds theory is actually one of the more mainstream ideas in science, despite seeming weird and fringe.
