In 1970 Hawking turned to the examination of the properties of black holes: the surface area of the event horizon(The boundary of a black hole) around a black hole could only increase or remain constant with time this area could never decrease From 1970 to 1974, Hawking provided mathematical proof for the hypothesis as the"No Hair Theorem": matter entering a black hole loses its shape, its chemical composition, and its distinction as matter or antimatter Since 1974 Hawking has studied the behavior of matter in a black hole in quantum mechanics. Quantum mechanics is a theory that describes black holes from which nothing was supposed to be able to escape could emit thermal rad iation, or heat Throughout the 1990s Hawking sought to explain the universe by incorporating all four basic types of interactions between matter and energy: strong nuclear interactions, weak nuclear interactions. electromagnetic interactions and gravitational interactions Universe in a Nutshell/ The lustrated Brief History of Time(1988) Black Holes and Baby Universes and Other Essays(1993), The Theory of Everything: The Origin and Fate of the Universe The Future of spacetime A Brief History of Time: From the Big Bang to black Holes In 1992 American filmmaker Errol Morris helped make all-time best seller A Brief History of Time into a film about Hawking's life and work What is ALS?
