Hawking's work followed his visit to Moscow in 1973 where the Soviet scientists Yakov Zeldovich and Alexei Starobinsky showed him that according to the quantum mechanical uncertainty principle, rotating black holes should create and emit particles.
In July 2012, Polchinski, together with two of his students — Ahmed Almheiri and James Sully — and fellow string theorist Donald Marolf at the University of California, Santa Barbara (UCSB), published a paper whose calculations about black hole radiation seemed to suggest that either Relativity Theory's equivalence principle is wrong, or else a key tenet of quantum mechanics is incorrect.
