'Secret of the universe' revealed: Scientists detect gravitational waves caused by two black holes colliding 1.3billion years ago - proving Einstein WAS right

Almost 100 years ago today, Albert Einstein predicted the existence of gravitational waves. These are ripples in the fabric of space-time that are set off by extremely violent, cosmic cataclysms in the early universe.

For nearly a century, physicists have been on the hunt for these elusive gravitational waves - and now that hunt is over. 

For the first time, scientists in the Ligo Scientific Collaboration (inset top right and bottom left) have directly observed the ripples of gravitational waves in an instrument on Earth. The scientists have also decoded the gravitational wave signal and determined its source. The gravitational wave is the product of a collision between two massive black holes, 1.3 billion light years away - a remarkably extreme event that has not been observed until now.
