Is Our Universe One of Many?

Astronomers have discovered a series of galaxies, close to the edge of our universe, being pulled towards a single point in the sky. This unexpected motion appears to be separate from the expansion of the universe and the researchers even suggest that a force beyond the visible universe is the culprit. The discovery has been named "dark flow". The fact that this "dark flow" seems to originating from beyond the known universe is allowing some scientists speculate that there may be other universes beyond ours, a multiverse of sorts.
