Gregg Braden (born June 28, 1954) is an American author of Consciousness literature, who wrote about the 2012 phenomenon and became noted for his claim that the magnetic polarity of the earth was about to reverse. Braden argued that the change in the earth's magnetic field might have effects on human DNA. He has also argued that human emotions affect DNA and that collective prayer may have healing physical effects. He has published many books through the Hay House publishing house. In 2009, his book Fractal Time was on the bestseller list of The New York Times.
