Here’s a quick update…
Last year in september, for the first time ever scientists Laser Interferometer Gravitational-Wave Observatory (LIGO) have observed Gravitational waves. The source of these waves were the product of the collision between two black holes into a giant single black hole occured 1.3 billion light years away
On December 16 2015 LIGO observatory for the second time detected a signal, which now confirmed as Gravitational waves. The scientists at LIGO converted these gravitational waves into sound waves, here’s how they sound!
This yet again proves the Einsteins theory of relativity..
When two dense objects such as neutron stars or black holes orbit each other, space-time is stirred by their motion and gravitational energy ripples throughout the universe.
