It is confirmed now – officially! Physicists said have just heard the faint, fleeting sound of two black holes – a billion light years away – colliding. This little sound and tone is what physicists are saying is the first direct established proof that Einstein’s Gravitational waves actually exist!Scientists Listen to Two Black Holes Colliding and Confirm Existence of Gravitational Waves!

The energy – of Black Holes colliding – which was 50 times greater than what all the starts in the Universe have put together was conveyed to us via vibrations in a pair of L-shaped antennas in Washington State and Louisiana known as Advanced Laser Interferometer Gravitational Wave Observatory (Ligo). Gravitational Waves are ripples in fabric of space and time that are caused by any large objects. These waves – or ripples – had hitherto never been seen.
The frequency of the chirp was too low for neutron stars, the physicists knew. Detailed analysis of its form told a tale of Brobdingnagian activities in a far corner of the universe: the last waltz of a pair of black holes shockingly larger than astrophysicists had been expecting.
One of them was 36 times as massive as the sun, the other 29. As they approached the end, at half the speed of light, they were circling each other 250 times a second.
And then the ringing stopped as the two holes coalesced into a single black hole, a trapdoor in space with the equivalent mass of 62 suns. All in a fifth of a second, Earth time.
Dr. Weiss said you could reproduce the chirp by running your fingernails across the keys of a piano from the low end to middle C.
Lost in the transformation was three solar masses’ worth of energy, vaporized into gravitational waves in an unseen and barely felt apocalypse. As visible light, that energy would be equivalent to a billion trillion suns.
Such Gravitational waves stretches space in one direction and shrinks it in another.
Why is the existence of Gravitational Waves so important? Because it can make it possible for us to “see” those parts of Universe which are hidden from conventional instruments like telescopes using visible light or x-rays/radio waves.
The scientists are saying that is bound to be one of greatest ever discoveries in physics and astronomy!
