Dark flow is the term that astronomers have coined for a recent cosmological discovery that is both thrilling and baffling: the galaxies of our universe are being pulled steadily towards a specific point in our universe, seemingly by a gravitational force. This was first detected by NASA in observations of what is known as the microwave background of the universe: radiation left over by the formation of our universe, or the big bang. During these observations hundreds of galaxies were seen to be moving at more than a million miles per hour towards a point in space between the constellations Centaurus and Vela. One explanation proposed by scientists: that the source of the gravitational pull is from an entirely different universe that is pressing up against ours. Dark flow has been used as evidence for the controversial Multiverse Theory, which is the possibility that our universe, rather than being singular and infinite, is actually only one of any number of parallel universes, all coming in and out of existence in an even larger and barely imaginable structure. This may seem unlikely at the very least, even ludicrous. However, if we were to consider the history of human belief about our place in the universe, it may start to sound a whole lot more plausible. After all, not even 500 years ago it was common knowledge that the sun revolved around the earth.
