'Ringing' of black hole detected for first time, confirms Einstein's theory of relativity

India Today  

When two black holes collide, they merge into one bigger black hole and ring like a struck bell, sending out ripples in space and time called gravitational waves. Because merging black holes experience crushing gravity, studies of these events allow researchers to test the general theory of relativity under extreme conditions. He specifically looked at simulations of LIGO's first detection of gravitational waves, from a black hole merger event known as GW150914. Einstein's theory of general relativity might fail someday "Newton's theory of gravity passes many tests where gravity is weak, but completely fails when it comes to describing gravity at its most extreme, like when it comes to trying to describe merging black holes.

Scientists have finally ‘heard’ the chorus of gravitational waves that ripple through the universe

Associated Press  

NEW YORK — Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently stretching and squeezing everything in the universe. They reported Wednesday that they were able to “hear” what are called low-frequency gravitational waves — changes in the fabric of the universe that are created by huge objects moving …

Physicists create new model of ringing black holes formed due to their collisions

Hindustan Times  

When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions. In the future, the new model can be used to learn more about the actual black hole collisions that have been routinely observed by LIGO ever since it made history …

Gravitational waves detected for first time from newly born black hole: Study

The Hindu  

Researchers have, for the first time, detected the gravitational waves from a newly born black hole, and found that the ringing pattern of the waves predicts the cosmic body’s mass and spin, providing more evidence for Einstein’s General Theory of Relativity. Einstein’s General Theory of Relativity predicted that a black hole of a given mass and spin can only produce …

Scientists confirm that black holes are hairless and ring like a bell, gravitationally speaking, when they're born

Firstpost  

If there’s one legacy of Albert Einstein that never ceases to make headlines, it’s his Theory of General Relativity. Black holes are one of the biggest enigmas in astrophysics, so it’s no surprise that new discoveries about black holes have also reaffirmed or challenged Einstein’s 103-year-old General Relativity theory. A black hole resulting from such a cosmically-quaking collision should itself …
