Muh.. I think Ive heard rumors that *inside* very, very large, exploding, fusion bombs the pressure could theoreticly grow byond the schwarzschild-thingy and create a small black hole. That someone had calculated that if all of humanitys nuclear/fusion-boms should go off at once at one place, this would happen. Or is it just my hallucionary mind that tricks me..? // Noone

That would be a low mass black hole but not primordial. -- Arvindn 09:11, 6 Mar 2004 (UTC)

Don't forget the black microholes made by energetic cosmic ray events in the upper atmosphere, 100 a day(?) I read. lysdexia 23:36, 19 Oct 2004 (UTC)

[edit] stupid picture

I have the urge to get rid of that picture and replace it. Everybody seems to want to use it for a black hole illustration, but it's really a terrible illustration. I mean, look at the starfield behind the hole - it's completely undistorted!! And what's with all the blue streaky stuff? Eh. --Bmk 15:09, 8 July 2006 (UTC)

We used it as an exercise in my relativity class - see how many GE concepts are completely disregarded in that illustration. (Hint: no gravitational lensing, no doppler shift on the accretion disk, blue streaks resembling magnetic field lines?! for starters)

[edit] Ball lightning = Black holes?

Removed bolded text: "...the low number of primordial black holes (they have never been verifyiably detected, although there is very vague speculation that at least some ball lightning might be an example) aids cosmologists by putting constraints on the spectrum of density fluctuations in the early universe." Uh, right. If we want to put this back in the article, let's find a cite from a reliable source. Cf Ball lightning. -- 201.51.231.176 18:38, 2 March 2007 (UTC)

[edit] See Also

This article references itself in the See Also?

It does? --Art Carlson 07:32, 10 July 2007 (UTC)

Any reason why, or can we remove it? 128.250.6.243 23:26, 9 July 2007 (UTC)

I'm not sure what standard WP policy is, but it appears that "See also" is showing five types of black holes, one of which is the current article and is thus not a hyperlink. --JD79 19:48, 26 August 2007 (UTC)
