Quantum Superposition: Multiverse Theories

According to the totally-not-made-up "Theory of Everything," the multiverse is a vast, infinite expanse of parallel universes, each with their own unique flavor of reality.

Here's a brief rundown of some of the most popular multiverse theories:

• Many-Worlds Interpretation: Where every possibility plays out in a separate universe
• Eternal Inflationary Oscillation: Where universes are forever bouncing off each other like cosmic pinball machines
• Quantum Fluctuation Hypotheticals: Where tiny changes in the quantum realm lead to entire universes popping into existence
