Update for Oct. 3, 2017: The historic discovery of gravitational waves of September 2015 has won the Nobel Prize for Physics. Half of the prize goes to physicists Kip Thorne and Barry Barish of Caltech, with half going to Rainer Weiss for their roles in the discovery. Gravitational waves are the "smoking gun" of the Big Bang. Predicted by Albert Einstein's theory of general relativity in 1916, a massive object like Earth distorts space-time around it like a bowling ball dropped on a trampoline. The larger the object, the more space-time is distorted by it.
