Einstein gravitational waves predictions proves right
Albert Einstein about a century ago predicted the existence of gravitational waves with his theory of relativity. Now scientists have found evidence that proves his prediction was true.
Einstein said space-time could be compared to a net, curving around massive objects like stars, planets, or black holes.
While scientists have previously been able to calculate gravitational waves, they had never before seen one directly.
Some 1.3 billion years ago, two black holes collided which sent forth a wobble that hurtled through space and arrived at Earth on September 14, 2015.
The phenomenon was observed by two US-based underground detectors, designed to spot tiny vibrations from passing gravitational ripples, a project known as LIGO. It took scientists months to verify the data and finally announce it.
