  1. Super massive black holes are generally what are found in the center of galaxies.
  2. I believe it is Neutron Stars which your last comment refers to.

  1. swat i sed! - innit?
  2. I've heard it for both - by science popularisers. Keep me out of it! 19:04, 22 August 2007 (CDT)


No fair! Doggedpersistance 19:05, 22 August 2007 (CDT)

  1. I misread #1, sorry. Locke Eye.jpg Always Watching...... 19:07, 22 August 2007 (CDT)

'S OK - at least you read it - unlike other people - Oh hello Dog, didn't notice you lying there.Keep me out of it! 19:10, 22 August 2007 (CDT)

Enough[edit]

Can't we come to some sort of compromise on this? Locke Eye.jpg Always Watching...... 19:42, 22 August 2007 (CDT)

How about you make the disputed section "hidden"? Bohdan
Remind me, how is that achieved? White text? Also, we can use the other article for parody, etc. Locke Eye.jpg Always Watching...... 19:46, 22 August 2007 (CDT)
I thought you knew how to do it. Bohdan
I forgot. Locke Eye.jpg Always Watching...... 19:48, 22 August 2007 (CDT)
I never even knew how to do it. Bohdan
You use <!-- ... -->. However, shouldn't someone ask tmtoulouse if he thinks it's funny? Instead of other people deciding for him? ThunderkatzHo! 19:52, 22 August 2007 (CDT)
Tmtoulouse and I have already had an epic edit war and wheel war over this, he even had 'Black hole" blocked from being created. B****n
Didn't he admit on his talk page once that he was one? ThunderkatzHo! 19:56, 22 August 2007 (CDT)
Yes, thats what started this whole thing. He was once a Cp sysop, and CP sysops are black holes. B****n
Doesn't that make you one? What happens when you have two black holes fighting each other? Could that destroy the space-time continuum? Am I asking pointless nerdy questions? ThunderkatzHo! 20:00, 22 August 2007 (CDT)
No, your questions are perfectly reasonable. I know that that makes me a black hole, but I never thought about it that way. I might have to think this over. B****n 20:01, 22 August 2007 (CDT)
I think that two black holes just merge to form one bigger one. Meaning that Bohdan and tmtoulouse are now, but once were not, the same user.--MountainTiger 20:03, 22 August 2007 (CDT)

funny?[edit]

Does that idiot (B****n) think he's funny? It's even polluting my talk page now! Keep me out of it! 19:48, 22 August 2007 (CDT) like this:? Boys will be boys! Keep me out of it! 20:04, 22 August 2007 (CDT)

  • Here is an idea: How about you stop insulting me and deleting my comments, and please just leave me alone? B****n
  • The comment is still there, she just made it hidden. Locke Eye.jpg Always Watching...... 20:09, 22 August 2007 (CDT)
  • I knew that, but for all practical purposes it has been deleted. B****n
  • Fuckin' asterisks. N****b, indeed. Where's ThunderKatz? humanbe in 20:15, 22 August 2007 (CDT)

Is it an insult to accurately describe someone? No comments have been deleted!Keep me out of it! 20:13, 22 August 2007 (CDT)

Please, leave me alone. B****n
Aw, iddums poor ickle boy getting ganged up on. Diddums den. Keep me out of it! 20:21, 22 August 2007 (CDT)
We've tormented him enough for today, perhaps we should lay off? Locke Eye.jpg Always Watching...... 20:24, 22 August 2007 (CDT)

If he stops vandalising Main space arts. Keep me out of it! 20:28, 22 August 2007 (CDT)

Hmmm.[edit]

"People have made statements like: "One teaspoonful of black hole material would weigh more than the earth." but this is a nonsense; a black hole is effectively a point of no dimension and infinite density."

At the very least it should just say "is nonsense", but also, we don't really have any evidence for this, not knowing how close matter would pack at black hole densities. We should also point out that, however "large" the hunk of matter may be, there is a larger still sphere from which no information (other than hawking radiation) can escape (the event horizon, right?) which is the largest diamater/distance around whatever is there at which the escape velocity is exactly = c. Inside, it might be higher, but ouside that distance, objects can still escape if they have enough energy. humanbe in 21:44, 3 September 2007 (CDT)

Theoretically a black hole is a point i.e. No spatial dimensions. See my nice new banner! Susan Jayne Garlicktalk 21:50, 3 September 2007 (CDT)

But it's theory with no observational context. Or can we throw in a footnote? I saw the banner, and the assertion of zero extension/infinite mass goes a bit beyong "outline" if we don't tell people's where to explore further.

"According to general relativity, a black hole's mass is entirely compressed into a region with zero volume, which means its density and gravitational pull are infinite, and so is the curvature of space-time which it causes. These infinite values cause most physical equations, including those of general relativity, to stop working at the center of a black hole. So physicists call the zero-volume, infinitely dense region at the center of a black hole a "singularity".

The singularity in a non-rotating, uncharged black hole is a point, in other words it has zero length, width and height.

But there is an important uncertainty about this description: quantum mechanics is as well-supported by mathematics and experimental evidence as general relativity, and does not allow objects to have zero size - so quantum mechanics says the center of a black hole is not a singularity but just a very large mass compressed into the smallest possible volume. At present we have no well-established theory which combines quantum mechanics and general relativity; and the most promising candidate, string theory, also does not allow objects to have zero size." from WP.

So while it might be a single point, we don't really know, and in an outline we shouldn't assert it. humanbe in 22:36, 3 September 2007 (CDT)

Mm - like it. wy not stick it in then? (going now - battry's runing down - even on charge it gets down to 30% if I internetting for 12 hours)Susan Jayne Garlicktalk 22:50, 3 September 2007 (CDT) (ps BH might even have negative size in eg Brane theory. - it might expand into some others of the 10/11/12 dimensions that exist instead - its called Brane theory 'cause it makes yer brain hurt!)

Yes, explaining the possibilities briefly make sense. We don't need be exhaustive ("outline...") but we should cover the options briefly. If we are going to have a black hole article, at least. One that doesn't just say "see tmtoulouse", anyway. humanbe in 22:58, 3 September 2007 (CDT)
Owsit grab yer now, H? Susan Jayne Garlicktalk 13:45, 4 September 2007 (CDT)
It's a lot better. Turning into a nice "outline". I put back in the hyopthesis of them having no dimensions, and added some headers for structure and to make it easier to edit. Now all we need is a picture of one... humanbe in 13:59, 4 September 2007 (CDT)

A piccy of tmtwolooooos perhaps? Susan Jayne Garlicktalk 14:30, 4 September 2007 (CDT)

Seriously though they had some nice movies of stars orbiting the galaxy centre bh on 'The Sky at Night' tother night. Real movies - not cgi stuff. Susan Jayne Garlicktalk 14:35, 4 September 2007 (CDT)

Thanx[edit]

Thanks DogP, I missed that! Susan Jayne Garlicktalk 12:57, 4 September 2007 (CDT)

Somewhere between a joke, a fearful thought, sci-fi and woowoo[edit]

I was thinking about the aestethic similarity between a black hole and our eye pupil. They both are seemingly holes, and black, and they "absorb" light (please explain the difference to me !) As I was thinking that the universe "before" the big bang was like one tiny black hole and a black hole is a singularity (no space and no time indeed), a fearful thought flashed in my mind! That's kind of a joke, but I need your rational reassurances on this (as i said i was into the woowoo stuffs a year ago). :D May one think that a behind a black hole there's a deity in a nonspacenontime form? and that the (maybe) singularity form of human consciousness is in that kind of form too so trace a relation between the two things?

I think it's all bullshit thinking, and kinda sci fi ahah because 1) there are many black holes, ergo... Many gooods? 2) black holes (as the laws of physics on very grand scale) seem not an inch antropomorphic. 3) if all our eyes were black holes, we would "swallow' everything around us!

Do i miss something?

Please pity me ahah i know these questions are half serious but i have to ask them to you rationals ahah They're a cross between a joke, sci fi, the truman show, pseudoscience, doubts. And maybe a future argument from religiousfreaks? :) :D

Gianga23 (talk) 11:59, 16 January 2014 (UTC)

Your pupils don't "absorb" light; they just allow light through to impact your retina. Black holes also don't really absorb light so much as it's just physically impossible for light not to fall into the singularity once it crosses the event horizon. Also, black holes generate massive gravitational fields. As far as I can tell, consciousness does not... - GrantC (talk) 15:07, 16 January 2014 (UTC)

Stephen Crothers[edit]

Has anyone heard this guy's arguments against black holes? I think it would be good to cover his arguments against the existence of black holes and explain why they are correct or wrong.

Fillums[edit]

No description of the various films and the positive bits/flaws therein - [1] (summat nasty coming up the plughole), [2] and the recent one. 82.44.143.26 (talk) 16:56, 9 March 2015 (UTC)

And what exactly are you wanting us to say about them? That science fiction isn't science reality isn't exactly an extraordinary insight in-and-of-itself. ikanreed You probably didn't deserve that 16:59, 9 March 2015 (UTC)

Films aren't completely real? Next you will be telling me Rambo taking on an entire communist army with a machine gun while none of them could hit him was fake. -EmeraldCityWanderer (talk) 16:49, 10 March 2015 (UTC)

'I read somewhere' that more people died in Eisenstein's film of the Russian Revolution than in the historical original. (And what was the Stallone film in which his character was asked to the effect 'Do you think you are Rambo?')

And is 'white hole' an oxymoron (being a showerhead-analogue rather than a plughole-analogue). 82.44.143.26 (talk) 19:25, 10 March 2015 (UTC)
