-
He postulated with other scientists that every black hole is fully described with its properties of mass, angular momentum and electric charge.
-
In 1974, he calculated that black holes must create and thermally emit subatomic particles, what is now known as Hawking radiation, until they use up their energy and evaporate. After analyzing gamma-ray emissions, Hawking suggested that tiny primitive black holes formed after the big bang.

He was the first to develop an equation to try to unify general relativity and quantum physics, a 'theory of everything
-
Hawking and Thomas Hertog proposed a theory based on top-down cosmology, according to which the universe did not have a single initial state and, therefore, physicists should not pretend to formulate a theory that explains the current configuration of the universe on the basis of a specific initial state.
