In 1916, a hundred years ago, Albert Einstein's creative genius mind, without the use of supercomputers and laser interferometers, predicted the existence of 'invisible' ripples in space and time continuum, 4th dimension. It is an important basis of his theory of general relativity, the equation includes gravitational waves. Scientists from LIGO confirmed their existence.
Nerds and science geeks around the world have raucous Big Bang Theory-like parties!
Theoretical physicist/cosmologist/genius Steven Hawking congratulates the team that finally found them.
