Separate Lives

Here's a handy one page missive on the theory of parallel universes, also known as the multiverse theory and hammed up in various Marvel movies. The theory that suggests that there could be multiple or even infinite universes existing alongside our own. These universes may have different physical laws, alternate histories, or variations of our own reality. Some key interpretations include:

1. Quantum Many-Worlds Interpretation – Proposed by Hugh Everett, this suggests that every quantum event spawns multiple branching realities where different outcomes occur.
2. Cosmic Inflation Theory – Some cosmologists propose that rapid expansion after the Big Bang could have created "bubble universes" with different physical properties.
3. String Theory & Extra Dimensions – String theory suggests extra spatial dimensions, potentially leading to parallel worlds interacting through quantum effects.
4. Brane* Theory – In some versions of string theory, our universe is a 3D "brane" floating in a higher-dimensional space where other branes (universes) could exist nearby.

While the concept is popular in science fiction, there is no direct evidence yet, and it remains only a theoretical possibility in modern physics. But check your own experiences, sometimes life plays little tricks on you ...

*Not a misspelling of brain either.
