The end of a black hole’s evolution may be a mind-bending kind of space-time independent of time. A new study proposes a method to tell how far any black hole is from reaching this end state.
Black holes are some of the weirdest things in the universe. They occur when mass is packed into a tiny volume, squished to its ultimate density.
Though observations suggest black holes are prevalent in the universe, scientists still don't really understand what goes on inside them. The equations of general relativity usually used to understand the physics of the universe break down in these cases.
"It is really beyond the physics we know," said Juan Antonio Valiente Kroon, a mathematician at Queen Mary, University of London. "To understand what happens inside a black hole, we need to invent new physics."
Mercifully, the physics for the end state of a black hole is somewhat simpler. A solution to the equations of general relativity was found that produced a situation called "Kerr spacetime." Scientists now think Kerr spacetime is what happens when a black hole has reached its final evolutionary state.
"Mainly the equations of relativity are so complex that for relativistic systems, the only way you can probe these equations is by means of computer," Valiente Kroon told SPACE.com. "Solutions like this Kerr solution are really exceptional. The Kerr solution is one of the few explicitly known solutions to general relativity that have a direct physical meaning."
Kerr spacetime is time-independent, meaning that nothing in Kerr spacetime changes over time. In effect, time stands still. A black hole in such a state is essentially stationary...

Must resist,must resist will not post pic..;>)
omg
no pics please.
do NOT google “mature black hoes” for pics either.
It's the spot on the floor where the back of my desk almost touches the wall.
Oh wait. That's a stationery black hole.
I’ll spare you this time... ;-)
Can’t touch this
Can’t touch this
Can’t touch this
Yea, Can’t touch this
I told you, can’t touch this
Too hype can’t touch this
Get me outta here, you can’t touch this

Lol, True!
True, but I can’t think of very many people who live in black holes to start with.... ;-)
/johnny
Heh heh....
Time stands still for no one,even Mrs Obama
I agree, but I do have a brother-in-law that will probably show up for the final formation about 5 minutes late.
/johnny
Always tardy, eh? I know some people like that too...lol. Real pain...
I take it that the writer has never spent time in Pontiac, MI for that matter?
You are on fire! I just keep cracking up.
Well, there is that. :)
