Gravitational waves detected for first time from newly born black hole: Study
The HinduResearchers 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 tones of a certain pitch and decay. By concentrating on the last few milliseconds of the signal, immediately following the chirp’s peak, the researchers were able to observe the newly formed black hole’s ringing. “Each frequency or tone corresponds to a vibrational frequency of the new black hole.” The team used the equations of General Theory of Relativity to calculate the newly formed black hole’s mass and spin using the detected information on its pitch and decay.
