Fastest Spinning Black Hole Ever Found
brian0918 writes, "NewScientist reports that researchers in Cambridge have detected a black hole spinning at nearly 1,000 times per second — the fastest ever recorded. From the article: 'McClintock's team examined a black hole in our galaxy called GRS 1915+105, which lies about 36,000 light years away. They found the innermost stable orbit around GRS 1915 is so close that the black hole must be spinning at nearly 1000 times per second. The finding supports the idea that only fast-spinning stars can collapse to create powerful explosions called long gamma-ray bursts.'"

I bet it would make for a crappy RAID array.
In addition to low throughput, I bet there would be some data loss.
ENOUGH OF THIS GAY BANTER, ON WITH THE TROLLING!!!

I was still in High School, I had a big cock and was horny all the time, jerked off at least 3 times a day. My body is small and slim with very little hair, 5"4",125lbs. My fat cut 7" cock looked huge on me. I had been jerking off thinking about gay sex lately, I was very turned on by the fantasy of having sex with an older man, and having a cock in my ass.
I got a job working after school and weekends at a antique shop, it was ran by 2 older gay gentleman, very nice gentleman who were always flirting and teasing me. An older very distinguished looking handsome customer came in the store, he was a silver haired fox who looked like he had money.
The owners knew him well, he bought a small end table and asked the owners if I could help him unload it at his house, I thought this was kind of suspicous since it didn't weigh much but my horniness and curiousity made me jump at the chance. We rode in his SUV to a big house in a ritzy neighborhood and I carried the end table into his house. He gave me a tour, it was huge and very nice, there was an indoor hot tub and he asked me if I wanted to soak for a while, I told him I didn't have a swim suit and he laughed and told me I could go without, he always did.
I was getting turned on so I started to undress, my tank top came off first and my back was turned to him and I pulled down my cutoffs, no underwear and bent over to finish removing my cutoffs, it was a turn on to expose my ass to him, he watched me climb into the hot tub, my cock was rock hard. I watched him take off his shirt, he had a sexy chest covered with silver hair, he pulled down his pants and underwear in one motion exposing a beautiful 8" cut cock, very fat. We sat in the tub for five minutes talking, he asked me if I wanted a massage, I moved over close to him with my back to him and sort of sat on his lap, I could feel that big cock, I started moving my ass around until it was between my cheeks, I moved up and down, it felt so hot, made my asshole spasm. He was rubbing my shoulders and back, he reached around and started massaging my inner thighs making my cock twitch, finally he started stroking my cock, I was so turned on it was all I could do not to cum. He had me stand up and started tonguing my ass while stroking my cock, I was in pleasure overload and exploded cum after about two minutes of this.
We went into his bedroom, still naked and dried off, he put his hands on my shoulders and gently pushed me to my knees, grabbed the back of my head and guided me to his cock. I sucked on it hungrily feeling it get harder in my mouth, when he was rock hard he guided me to the bed and had me lay on my stomach. He ate my ass again this time harder, getting his tongue up inside me, this made my cock hard again, I relaxed and felt my boypussie open up. Next he slowly inserted one of his fingers , it kind of hurt at first but then I started to love the feeling. Two fingers was next with some lube, he two finger fucked me for along time, I loved how it felt, like I was getting stretched. I was moaning and moving my ass up and down.
He stopped and put his big cock back in my mouth, I sucked him for maybe a minute and he pulled out and rolled on a condom, had me get down doggie style got behind me and pushed that big cock head against my tight hole. He slowly pushed, I thought it was to big and would never fit, all of a sudden it popped in, the sensation took my breath away, it felt so huge and it hurt a little, but I was starting to relax and it was feeling better by the second.
He slowly pushed in until he was deep inside me and moved in and out very slowly to start with, it still burned but the thought of getting fucked, having a big cock inside me was such a turn on.
He fucked me for a long time, after I got used to it and fully relaxed the feeling was pure pleasure. My cock was rock hard.
The pace got faster and harder, finally I came again, without even touching my cock, such intense pleasure. He came and stayed inside me, I layed flat on my stomch with him still inside me, he slowly went limp, slipped out of me and rolled off me.

The original article is from The Astrophysical Journal and I'm not sure if you can read this but I'll link it here. I have an account so that may be unreachable, if it is try the PDF of it or the abstract. I often enjoy reading the original article no matter how large and complex it is. If anything, it causes me to look up more terms so that I feel like I'm learning something.

I find it amazing that they can find an object which emits absolutely no light, halfway across the galaxy, and yet it's still so hard to find planets. I know they find the black holes by their accretion discs, but I still think it's remarkable.

People, what we have is a model, not an observation. As TFA says, this model is based on assumptions, though fewer assumptions in the past:"Now, astronomers have measured the spin of a black hole with a new method that requires fewer assumptions."
The black hole may indeed be spinning at 1000 revs, or is might just be that one of the model assumptions is invalid.
Engineering is the art of compromise.
They didn't mention it in the article but thankfully I'm a black hole expert :-D There's a theory that says since the singularity is infinitely small then technically no matter is actually moving when it's rotating so it doesn't have to obey the speed of light speed limit and may be able to rotate faster than the speed of light. No idea how they can measure the speed if there's no radius but anyway, if it gets up to that speed they theorize that it will completely stop emitting gravity and either just sit there or explode, but most likely just sit there. This is the only known (well, in theory) way to "destroy" a black hole so when one comes and sucks up Pluto, thus ending that stupid debate, and is heading for Earth, we can just shoot particles into it at the correct angle and it will absorb the kinetic energy and translate it into spin and eventually spin so fast it effectively isn't dangerous anymore :)

Politicians are seeking ways to utilize this new power source. Top RNC officials were quoted as saying, "With the ability to spin this fast, we may have the means necessary to win the Iraq war by rapidly spinning disinformation." Democratic officials were equally hopeful, offering a cautious, "We'll be able to flip-flop on issues MUCH more quickly now."

So the question is, whos grave is it and what did we do to get them to spin that fast?
"Have you ever thought about just turning off the TV, sitting down with your kids, and hitting them?"
Pretty fast! Now how large would the black hole need to be to approach the speed of light at the outer edge?
...some astronomers have expressed doubt that stars would be spinning fast enough at this stage in their lives.
Now, i'm not an astrophysicist, but it seems to me that if a star had any spin at all before collapsing into a black hole, that spin would be magnified quite substantially, to conserve angular momentum (y'know, like a figure skater, or you spinning on your office chair).

If you'd like to see the whole article, as published in the Astrophysical Journal, you can find it on the astro-ph journal pre-print server. It's not the "official" journal version, but it should be identical to it (and was submitted to the preprint server by the authors).
I couldn't tell if you were experimenting with poor-man's cryogenics or looking for the orange sherbet.
I'm no genius in physics, but I thought the only way you could measure the absolute speed or position of something (at least on the sub atomic level) is to bounce another particle off of it (light, electron, quark, whatever) (and never both at the same time). Same applies to larger objects in every day life, where you typically just bounce light off them.
So how the hell do you measure the rotational speed of a black hole, when by definition every particle you shoot at it gets sucked in never to return?
cue the goatse jokes!
Infinite time means everything that can happen, will. You being you is absolutely incidental. You do not exist.
Well, since a 747 is significantly less massive than a black hole (except for very few - if any - primordial black holes, and even then, after swallowing Pluto they'd definitely be more massive), and BBs are significantly bigger than most particles, I'd say trying to deflect a 747 with BBs would actually be much, much easier. Assuming you have the correct angle, of course... :P
(Never mind the fact that by the time said black hole swallowed up Pluto it'd already have totally destroyed our orbital trajectory.)

of the black hole?
If an ogject is orbiting at 1,000 times per second in order for it to remain just below the speed of light it would have to be NO farther than about 30 miles from the center of the black hole.
It's got to be on the verge of exploding. I wonder what effect the explosion will have here on Earth at 38,000 light years away?

Here's a 20 mile diameter pulsar spinning at 716 Hertz. When you factor in the increase in rotational speed with the black hole contraction, 1K sounds real plausible.

Some astrophysicists say that some spinning cylindrical black holes warp spacetime enough that a projectile moving through its nearby region gets its velocity rotated to travel through time instead of a spatial axis. Is this new one the longest wormhole yet found?

Around stationary black holes, time does not work that way. Around spinning black holes, time *really* doesn't work that way (I could have sworn we hadn't even solved the GR metric for that system yet...). Unfortunately, reality has the tendancy to ignore the way that I, at least, think it should behave.
Basic idea -- large gravitational well means that distances are streeeeeeeetched and so is time. In the local frame of reference, the orbiting object is moving much slower than we're seeing it here in the bookkeeper frame. Of course, beyond that and my undergraduate level GR class is no longer really adequate enough to be worth mention.
Yeah. Would you choose a neurosurgeon who pokes around people's brains in his spare time? I wouldn't.
If I remember correctly, centrifugal force as we know it actually reverses near a black hole. Pulling inward instead of outward. A rotating black hole may be compressed further by its rotation. Maybe someone familiar with the phenomena can shed more light.

Odd. So, does the Schwarzschild radius actually shrink as a black hole spins faster? And for curiosity's sake, if a large, incredibly strong interstellar body were to clip one of these fast-spinning black holes (assuming it isn't stretched into oblivion), would the part that touches the event horizon simply be sheered off, like a knife cutting through butter, or would be ripped off, like tearing a chunk of bread from its whole?
Likewise, does anyone know if the speed at which a black hole spins has any relationship with how quickly it evaporates?

Every black hole has a central singularity. These are points where mathematical modeling fails. That is because we assume every thing is 3-D. But the fact of the matter is these centers of black holes are singularities in 3-D but are actually simply transition points in higher dimensions..." [source]

Is there any data on its diameter/circumference? If it's spinning at 1000 RPS, and it's more than 186 miles around then wouldn't its surface (event horizon?) be traveling FTL?
It must have been something you assimilated. . . .
There's one thing I don't understand about black holes. I've read that a black hole is so massive that space itself is warped around it. This warping means that a straight line that starts at the center will return to the center. It returns even though in its local context it is straight. But don't gravitons move like light? So how does the force of gravity escape? No light or other signal can escape... And yet gravity can! Weird.

That is true. However, this is currently our best estimate, and the theory applied is pretty well-respected. It may be interesting to know that this finding supports a 1997 suggestion that this particular black hole spins very close to its maximum. The 1997 paper attempted to explain in theory the x-ray jets this black hole emits by suggesting it spins. In contrast, this new paper actually documents an attempt to measure the spin.
Anyway, assuming the theory is correct, their method sounds pretty plausible to me (also assuming I'm understanding the paper and article right).
Basically, the size of a black hole event horizon depends mainly on its mass. However, if the black hole is spinning (most or all are believed to due to conservation of momentum), the event horizon contracts due to frame dragging.
Of course, we can't directly see the event horizon to measure it like we can measure the sun's radius. These black holes are far too distant to resolve. But, matter falling into the black hole is heated up due to friction. Just before it passes the event horizon, it gets so hot it emits x-rays that are detectable from earth.
The clever part is that the energy of the x-rays is correlated to the emitting particle's radius from the center of the black hole, since as particles spiral in further, they heat up more and more. So if you know the mass and can measure the highest frequency of the emissions, you can calculate the rate of spin. Of course, finding the mass and measuring those x-rays is not at all trivial, and the final step of calculating the spin probably took the 6 researchers who published the paper a year or so worth of work.

Spinning black holes with hair would be sooo hot!
Just something that I've always wondered about.. how do you measure the spin of something that is essentially, for an outside observer, a spherical event horizon containing some amount of mass? I would think that in order for something to be meaningfully spinning, it's got to have something you can put your finger on so you can "sense" the spin. Is a black hole's gravity field not uniform, or what exactly does one mean by a BH's spin?
I want to play Free Market with a drowning Libertarian.
At 36,000 light years away, the black hole was spinning; who knows what's really going on now.
But... it could be just the right size that it becomes the mass of a 747 right before it collides with Pluto. Of course, then we also have all the radiation issues to worry about, too.

For a second there I thought we had an article on the Bush Whitehouse. Must be 2nd fastest black hole, but don't worry because us Americans love to be #1.
While sensible space travelers have learned to avoid the area, primarily due to the god-awful noise of the singularity, Hollywood special-effects moguls are on a mission to record that same noise for an upcoming sequel to Star Wars. The exotic sounds of space are half the attraction, they say.

Don't black holes drag space time around with them? So relative to an observer they are going faster than c, but relative to the space they occupy they are not.
