How many “yous” exist?

Infinite doppelgängers may explain quantum probabilities

AN IDENTICAL copy of you is also reading this story. This twin is the same in every way, living on an Earth and in a universe that looks exactly like our own. And there may be an infinite number of them. Such doppelgängers could be a natural consequence of our present conception of the universe. Now, some physicists say they could pose a serious problem for quantum mechanics. But a possible fix may also be in sight, and it could help tie abstract quantum concepts to concrete physical causes.

Now, I struggled with algebra in school, so this stuff is way over my head, but whew. Multiple mes? Yikes!
