The information locked inside black holes could be detected by feeling their 'hair,' new research suggests.
As far as we understand them (which, admittedly, is not very much), black holes are suspiciously simple objects. Regardless of what falls in... black holes can be described by three and only three simple numbers: charge, mass and spin.
The reason this is suspicious is that something had to happen to all that juicy information that fell into those two black holes.
The simplest solution is the theorem, first coined by the American physicist John Wheeler, that "black holes have no hair" — they have no extra information encoded in them or on them. Just their mass, electric charge and spin. Everything else is simply destroyed (somehow) beyond the event horizon, locked away from the universe forever and ever.
But in 1974, Stephen Hawking proposed a revolutionary idea: black holes aren't inescapable cosmic vacuum cleaners; rather, subatomic particles might flee black holes through an exotic quantum process, which would result in the release of radiation from their surfaces.
As far as we know, Hawking radiation doesn't carry any information away with it.
A new study, published June 22 to the arXiv database (but not yet peer reviewed), suggests one way to find these silky strands: a gravitational wave detection.
When black holes merge, they release a fury of gravitational waves that ripple throughout the cosmos. Despite the incredible energies of these collisions, the gravitational waves from these cosmic smashups are exceptionally weak. By the time these waves wash over Earth, they're barely capable of nudging individual atoms.
There could be "soft hair" on the black holes — just a little bit of information, structured in a way that is challenging to detect.

lol...What you did there, I saw it!
Very restrained.
You can tell she wants to post that picture of Biden ‘sniffing’ the young girls hair.
But she did not.
Aplus.
This is the most racist astronomy thread ... ever! Or sexist. I’m not sure.
This is nothing but babbling nonsense. It uses words like “soft hair”. “information” “ripples in space time” that have common meanings, but they are used in a totally different context without defining the meaning. That’s the absolute definition of babble. If you’re not a member of his cult, he’s speaking nonsense.
Saw a kids tee shirt today!
It said
HIDING from BIDEN
They lost me decades ago with the nonsense about “Up/Down” vs. “Top/Bottom” quarks. It doesn’t even make sense.
What if a black hole is one of those shaved jobs....?

Always good to know we have a theoretical astrophysicist in our midst.
Can we come to you when we have concerns about gravitrons?
OK, this is getting a bit too explicit.
With a hot pink center ,like a steak ?
Here it is midnight, and my 7:30 thought that this thread would get a near record response sure was wrong...
Meant 8:30... Not 7:30...
I;m just surprised nobody has made a crack yet about a certain planet.
Wisecrack, that is.
Thanks BenLurkin.
You may. Of course, you'll have to wait until someone actually discovers one. I only comment about facts.
So you stayed at a Holiday Inn Express last night?
You just had to go there, didn’t you? :)
