The quantum theory which states that all possible quantum universes can exist simultaneuously. It solves the Schrodinger cat problem by stating that the universe splits at each quantum junture, and hence the cat is alive in one universe and dead in another.

In other words, everything that can happen, does happen (just in seperate worlds). Every possibility plays itself out in one universe or another.
Recently, an increasing number of physicists have voiced their support for the Many Worlds Theory.
