Life's Great Mysteries - Do infinite parallel universes actually exist?

My Bridgers series is a sci-fi series of novels in which our heroes try to save humanity by "bridging" as many people as possible to alternate versions of Earth. Let's examine this basic science idea of the Bridgers series, the rather mind-bending concept of infinite parallel universes.

While there are certainly cosmologists who are skeptical of the concept, it is important to point out that multiple parallel universes is not an idea scientists simply came up with using their imaginations. Instead, the concept is a mathematical consequence of our current theories in physics, particularly quantum mechanics and string theory. What this means, essentially, is that even those physicists who are skeptical of the idea must examine it as a real possibility (even if they do so reluctantly).

If we assume quantum mechanics and string theory are not completely wrong, then it is important for scientists to examine all of the mathematical consequences of those theories. Even if those consequences (such as parallel universes) seem strange to us.

There are at least five important scientific theories that suggest the existence of multiple universes. For example, the theory of quantum mechanics suggests the possibility of "daughter universes" (this is my favorite). Quantum mechanics describes things in terms of probabilities rather than definite outcomes. The mathematics of quantum mechanics suggest that every possible outcome of every situation actually occurs—in its own separate universe.

Everything is made up of tiny particles, and what this "daughter universes" concept boils down to is that there could be infinite parallel universes, each of them differing by the position of only one particle.

The concept boggles the mind. We may never know for sure if infinite universes are real, but the concept certainly makes for a fun story.
