Physicists have predicted that at the Big Bang, black holes with sizes from 10^-5 grams up to perhaps solar mass size might have been formed. Use the above formulae to predict the mass range of the black holes would have lasted as long as the present age of the universe, between 9 billion to 15 billion years, and which should just now be evaporating completely away. Predict what the final few thousand years of life would look like for such black holes, by computing their REMAINING mass, the temperature of the radiation they are producing, and their power.
