<\/div>\nAt any rate, even the heaviest supermassive black holes, which weigh in at about 10 billion times the mass of the Sun, will disappear, or \u2018evaporate\u2019, after about 10\u00b9\u00ba\u00ba years (that\u2019s 1 followed by 100 zeroes!).<\/p>\n
If the expansion one day runs out of steam and the Universe re-collapses down to a \u2018big crunch\u2019, the Universe\u2019s black holes will all merge.<\/p>\n
It is only relatively recently that physicists have managed to simulate the merger of two black holes on a computer.<\/p>\n
If two black holes did merge, presumably the result would be one huge, \u2018cosmic\u2019 black hole.<\/p> <\/body><\/html>\n
