Black hole spins as fast as it can 950 times a second....

Favorite MW quote:"dat be rotatin!" <img src="/images/icons/laugh.gif" /><br /><br />Wow does that mean th gravity increases with the speed of the rotation? If not I suppose there has to be some relation to rotation and gravity... <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

The Rossi X-ray Timing Explorer and INTEGRAL spacecraft found that the neutron star XTE J1739-285 rotates at 1122 revs/second. <div class="Discussion_UserSignature"> </div>

 

[derekmcd]

Indeed. That would put the surface speed at the equator at about 1/10th of C. Amazing how strong the gravitional forces must be to hold it together. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

IIRC the theoretical limit is 1500 rps. <div class="Discussion_UserSignature"> </div>

 

[why06]

So the faster it spins the closer things can orbit before getting sucked. What would be the minimum event horizon then? <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

That would be a very fast ride. New ride at the amusement parks The Black Hole.

If you could stand on its surface, you could literally sniff your heals.

Is there evidence of a spinning black hole?

 

[MeteorWayne]

Did you read the story I linked to? <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

[thamior]

Of course there's evidence, lol. <br />Have you all read about Frame Dragging? Quite an interesting topic.. <div class="Discussion_UserSignature"> <p>--What is the truth but a wisp of truly un-attainable information.  There is no absolute truth anyways, only false perceptions and misgivings.--     </p> </div>

 

[derekmcd]

Current thought is most black holes rotate. Conservation of angular momentum. A rotating star that collapses will continue to rotate. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

 

[alokmohan]

Good thoughts.But theoritical only.

 

[enigma10]

Is there any evidence to support otherwise? <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

Hey check out naked singularities:<br /><br /><br />can a blackhole ever spin this fast?<br />http://en.wikipedia.org/wiki/Naked_singularity <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

 

[enigma10]

Great. A computer simulation to support a possible state of a singularity. I stress the word possible. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

I will only study naked singularities if they are of the female persuasion. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

..hey whatever works for you... If that's the thing you do with black holes Im not going to get in your way... <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

Enigma,I rethought it .You are correct.

 

[dragon04]

I'm trying to visualize an object that is rotating at <b>just</b> under the maximum.<br /><br />Pancakes, anyone? <div class="Discussion_UserSignature"> <em>"2012.. Year of the Dragon!! Get on the Dragon Wagon!".</em> </div>

Don't put your mouth on that!<br /><br />As Homer would say:<br /><br />MMmmmmm, maple syrup accretion disk, {drool} <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

[alokmohan]

A black hole has mass.Two other parameters is not must.They may spin,they may not .Depends on the original star.Thus black hole may be non spinning,non charged.Spinning not charged,Spinning and charged.

 

[alokmohan]

To study a black hole I prefer to have non spinning black hole.

 

[nexium]

I agree in theory, but how does the black hole dispose of all of the charge and rotation it had as a star? In the real world; all black holes have at least a slight charge and rotate slowly (ie one degree per million years) with respect to Earth and most anything else we can imagine. Rotation is relative and so is charge sort of relative. Are there any electrons or protons inside the event horizon of a million ton black hole, if any black holes have that small a mass? As we observe a black hole we are seeing the net charge and rotation of the accreation disk. We can only theorize charge and rotation conditions inside the event horizon. In my opinion, nothing is different (to a local observer) a nanometer outside the event horizon, compared to a nanometer inside the event horizon, except for extremely low mass black holes, if any.
