How the Universe Has Cooled Since the Big Bang Fits Big Bang Theory


"According to the Big Bang theory, the temperature of the cosmic
background radiation drops smoothly as the Universe expands. "That's
just what we see in our measurements. The Universe of a few billion
years ago was a few degrees warmer than it is now, exactly as the Big
Bang Theory predicts," said research team leader Dr Sebastien Muller
of Onsala Space Observatory at Chalmers University of Technology in
Sweden."

And so the temperature of the universe continues to decline as time
passes, giving even the biggest black holes the opportunity to
evaporate.


Double-A


* *The more massive the black hole, the colder it is and the
* *longer it will take to evaporate

* *The Lifetime of a 1 kg black hole is 8.4e-17 seconds

* *The lifetime of a 10 solar mass black hole is 2.1e70 years

* *The lifetime of a 10^6 solar mass black hole is 2.1e85 years


Or, a BH could just as easily be 1e6 K, because no IR or any other
spectrum can escape.
