Mar 13, 2023 · Proposed by physicist Hugh Everett in 1957, the many-worlds interpretation predicts the presence of branching timelines, or alternate realities in which our decisions play out differently ...
- Eternal inflation, the Big Bang theory and parallel universes. Around 13.7 billion years ago, everything we know of was an infinitesimal singularity. Then, according to the Big Bang theory, it burst into action, inflating faster than the speed of light in all directions for a tiny fraction of a second.
- Quantum mechanics and parallel universes. Some researchers base their ideas of parallel universes on quantum mechanics, the mathematical description of subatomic particles.
- Infinite space, infinite universes? Some physicists believe in a flatter version of multiple universes. That is, if the universe that we live in goes on forever, there are only so many ways that the building blocks of matter can arrange themselves as they assemble across infinite space.
- The mirror-image universe. In a relatively recent addition to the pantheon of multiverse theories, researchers from the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, have proposed that the universe began at the Big Bang — and on the opposite side of the Big Bang timeline, stretching backwards in time, a universe once existed that was the exact mirror image of our own.
Jun 20, 2022 · Today, many of the world’s top physicists are embarking on this cosmic quest, whose far-reaching reverberations span our understanding of reality and the meaning of existence.
Mar 12, 2019 · Physicists have long suspected that quantum mechanics allows two observers to experience different, conflicting realities. Now they’ve performed the first experiment that proves it.
Jun 25, 2024 · One hundred years ago, we discovered there were other galaxies beyond our own. Now, we might be on the verge of another discovery: that there are other universes.

Aug 1, 2011 · Parallel universes may or may not exist; the case is unproved. We are going to have to live with that uncertainty. Nothing is wrong with scientifically based philosophical speculation,...
Apr 19, 2016 · First, if scientists have tried, and failed, to come up with an alternative theory that explains a phenomenon well, that counts as evidence in favor of the original theory. Second, if a theory ...
