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.
The study, published in the journal Physical Review Letters, increases the possibility that black holes exhibit only three observable properties – mass, spin, and electric charge.
All other properties, the study noted, could be swallowed up by the black hole itself, and are unobservable.
