Stephen Hawking's idea that black holes evaporate puts two fundamental tenets of physics into conflict.

In 1974 , he predicted that even though nothing is supposed to escape a black hole's event horizon, these cosmic beasts can actually emit particles.

Hawking sparked a debate that has continued for more than 50 years .

A black hole with a mass of the sun could take 10^67 years to fully evaporate.
