Scientists conducting a study of the movement of galaxy clusters have discovered a mysterious pattern of motion, dubbed dark flow, that is pulling 1400 clusters of galaxies towards a single point in the cosmos, at the edge of the universe.  The strange phenomenon has baffled scientists.  One exotic explanation is that the flow is a result of a quantum entanglement that once linked our universe with another.
