[Date Answered] February 3, 2010 [Questioner (age, location)] Narayanan (India) [Answer] I don't think there is anything considered "absolute" regarding black holes. One of the hypothesized fate of a black hole depends on the temperature of its surroundings. If the universe is cold enough it will evaporate incredibly slowly. If the background is warmer it will grow slowly until the temperature drops low enough for the hole to start to evaporate. [Question] 
What is the absolute fate of a Black Hole ?
