What to know about Statistical technique could uncover secrets of 'ringing' black holes

Researchers from the University of Cambridge have developed a Bayesian statistical method to more accurately identify and catalog the gravitational wave frequencies, known as quasinormal modes, produced when black holes merge. This technique allows for the detection of fundamental notes, overtones, and nonlinear modes, which can be used to test Einstein's general theory of relativity.

What happened

Statistical technique could uncover secrets of 'ringing' black holes Gaby Clark Scientific Editor Robert Egan Associate Editor Researchers have developed a technique to analyze how black holes "ring" when they collide and merge: one of the universe's most…

Why it matters

When black holes merge, the collision produces a new, larger black hole that "rings" like a plucked guitar string or a bell while it settles into its final, stable shape.

Common ground

But instead of sound waves, the new black hole rings with gravitational waves: ripples in spacetime first predicted by Albert Einstein.
