Skip to comments.Scientists detect the ringing of a newborn black hole for the first time

If Albert Einstein's theory of general relativity holds true, then a black hole, born from the cosmically quaking collisions of two massive black holes, should itself "ring" in the aftermath, producing gravitational waves much like a struck bell reverbates sound waves. Einstein predicted that the particular pitch and decay of these gravitational waves should be a direct signature of the newly formed black hole's mass and spin.
Now, physicists from MIT and elsewhere have "heard" the ringing of an infant black hole for the first time, and found that the pattern of this ringing does, in fact, predict the black hole's mass and spinmore evidence that Einstein was right all along.
The findings, published today in Physical Review Letters, also favor the idea that black holes lack any sort of "hair"a metaphor referring to the idea that black holes, according to Einstein's theory, should exhibit just three observable properties: mass, spin, and electric charge. All other characteristics, which the physicist John Wheeler termed "hair," should be swallowed up by the black hole itself, and would therefore be unobservable.

I didn't know they rang...
Only the polite ones.
Gotta now fit it with a pacifier. Could be the next thing, after we fix Climate Change.
Somebody want to get that?
Planned Parenthood knows how to get rid of newborns.....
You would thing they would call first....................
"One Ringy-Dingy..Two Ringy-Dingy...."
Black holes got tinnitus. Who knew?
If the grant money is available to study ringing black holes, then black holes ring. They will dance too for extra funding.
Pete Buttplug wants to abort it.
I believe Climate Change...
but it really Really REALLY must want to change.
Excellent news... We can sleep better at night knowing that the murderous abortion craze has not reached the black hole civilizations... Yet...
Send the TIDE, it works for ring around the collar.
Probably a party line, too
Black holes with hair around them. TMI!
Black holes with hair. Paging Mayor Buttbutter. Paving Mayor Buttbutter.
*one ringy-dingy ping*
