Multiverse may be confirmed
The existence of other universes may be capable of confirmation. Laura Mersini-Houghton suggests this has already occurred by the observation of an enormous hole in the cosmic microwave background radiation by NASA's WMAP satellite, which she suggest could be the imprint of another universe.
Furthermore, according to physicist Roger Penrose, the same WMAP data could confirm his own theory that the universe will ultimately evolve to a state similar to the early universe - smooth and low entropy - as a result of entropy being removed from the universe through the evaporation of black holes.
