How Parallel Universes Actually Work, Scientifically

Parallel existence are basically the most popular trope in science fabrication , because Batman and Spider - Man in alternate universe costume are awesome , and also human existence is inherently full of frightening , soul - break down regret . But how does the scientific discipline really work ?

Our old friendMinutePhysicsexplains that there are three poser of multiverse theory . There ’s the Bubble Universe / grim yap theory , which state that our evident universe might just be one part of a greater whole , and other part of the universe are so far aside we ’ll never see them , or are inside black hole , and therefore unobservable . Then there ’s String Theory ’s take , that we live on a three dimensional planer inside of a larger nine - dimensional population , wherein other three dimensional “ membranes ” ( universes ) could exist . And finally there ’s the quantum mechanically skillful one you ’re probably most familiar with , where every multiple choice problem that ’s ever pass off in the reality ( will you step in that pool ? Will you NOT step in that pool and fall into a sewer and marry into a sept of rat world-beater alternatively ? ) actually cause novel population to form , with each theory actually happening in one .

The thing to remember is that these are n’t just philosophical quandaries . None of the models have been proven , but tests exist , or are being develop , to test and seek to sustain them . [ MinutePhysics ]
