At the root of this theory is the Many-Worlds interpretation of Quantum Mechanics. The gist is that atoms can exist in many states at the same time. So technically there are multiple realities in parallel (simultaneous) universes.
Ok. It seems like just another one of those interpretations of quantum mechanics which gave rise to sites like this. So let me explain. Think of a machine which can reset its memory to a previous (backed up) state when it encounters a glitch. Suppose, the computer learns that there is an impending asteroid strike (my favourite) which has been scaring us over and over. Now suppose the machine resets its memory.
An observer sitting next to the machine can verify that the "same machine" will still face disaster after the reset. But from the perspective of the machine's reset memory, the state of the universe in the many-worlds scenario becomes "undetermined". After all, for all the machine knows, the reset occurred for a mundane reason, such as a crash of its operating system.
Now, all the undetermined possibilities are open to the machine. So, the machine, it has been dealt a whole new set of cards. It starts afresh. So to the machine it has switched to a parallel universe. The probability (to the machine) that the reset was because of an impending asteroid strike is close to zero. So by simple probability, the chances that its in a new and free world are more.
If we had brains where quantum uncertainties were entertained, we would all be aceing our tests, getting into the top universities and scoring the most amazing girls.

Ever considered reading Richard Feynman ? You should, that is, if you are going to probe further on Multiple Universes :)
