The article says: "The best known temperature for a Kugelblitz to form is 141 billion billion billion Kelvin". I've done plenty of work on general relativity, this makes no sense to me: a sufficient quantity of electromagnetic radiation can form a black hole regardless of the temperature. Since no citation is provided, I'm going to delete this. If someone can explain it, we can restore it. John Baez (talk) 03:15, 3 February 2013 (UTC)
Check the history. It was obviously simple vandalism, or at best puerile nonsense. --Florian Blaschke (talk) 13:19, 8 January 2014 (UTC)
