Some of the world's leading physicists believe they have found startling new evidence showing the existence of universes other than our own. One possibility is that the universe is so vast that an exact replica of our solar system, our planet and ourselves exists many times over. These Doppelganger Universes exist within our own Universe; in what scientist now call "The Multiverse." If proof is found it will change our lives, our minds, our planet, our science and our universe.

Michio Kaku: We are experiencing an existential shock. Our worldview has been shattered with the realization that, yes, there could be parallel universes.
Alex Fillipenko: I mean, it's just a mind-boggling idea that there may be, essentially, exact replicas of us out there in the vastness of space.
Clifford Johnson: The idea of a parallel universe is part of our popular culture. People all around us think of it every day, but usually in terms of fiction. One of the real exciting things is that scientists today are trying to see whether parallel universes are a physical reality.
Narrator: Amazing new discoveries about the true size of the universe seem to indicate that all that we see is not all that there is.
Narrator: Remarkably, there may be four types of parallel universe out there. One kind could exist in the same exact space we're in, but it is so far away we cannot see it or reach it. In another scenario, multiple other universes could be in giant cosmic soap bubbles adrift in a cosmic sea of giant bubbles.
Michio Kaku: Revolutionary developments have changed the entire landscape. Data from outer space have given us a new look at cosmology and satellite data indicates there could be parallel universes.
Narrator: In yet another scenario, many parallel universes occupy the same space and time as our universe, but because they are in different dimensions, they are invisible. In yet another, all the laws of physics are different, so everything looks completely different.
Michio Kaku: New theories, called string theories, are giving us worlds of higher dimensions. Quantum physics at the microscopic scale is also revealing to us the fact there could be parallel universes.
Narrator: To keep things simple, physicists have divided parallel universes into different levels. Meet the level-one parallel universe : according to physicists, the level-one parallel universe is just an extension of our own universe.
Alex Fillipenko: Now that's the kind of universe which is really sort of part of our space, of our giant space, but it's so far away that we can't see it. Narrator: The level-one parallel universe is based on the idea that the universe is infinite in size. If true, just by the shear mathematical odds, there must be out there in endless space, an exact copy of the solar system, the Earth and all the people on it.
