Matt O’Dowd discusses the details of the many worlds theory and why it’s not so far-fetched to think that our reality is simply one of an infinite number of realities existing within space time.

The Copenhagen interpretation of quantum mechanics tells us that observation collapses a probability wave into a single definitive outcome, but this isn’t the only interpretation of quantum mechanics. The many worlds theory proposes that the wavefunction never actually collapses. The observer simply follows one of those many possible paths into their present reality while all the other paths continue on independent of the observer. Each of these paths branches off into an entirely different reality.
