What did Stephen Hawking do in 1988?

A Brief History of Time: From the Big Bang to Black Holes is a book on theoretical cosmology by English physicist Stephen Hawking. It was first published in 1988. Hawking wrote the book for readers who had no prior knowledge of physics and people who are interested in learning something new about interesting subjects.

What was Stephen Hawking’s theory in 1983?

In 1983, Hawking and another researcher, physicist James Hartle, proposed what is known as the ‘no boundary theory’ or the ‘Hartle-Hawking state’. They proposed that, prior to the Big Bang, there was space, but no time. So the Universe, when it began, expanded from a single point, but doesn’t have a boundary.

In 1970, Hawking postulated what became known as the second law of black hole dynamics, that the event horizon of a black hole can never get smaller. With James M. Bardeen and Brandon Carter, he proposed the four laws of black hole mechanics, drawing an analogy with thermodynamics.

What did Stephen Hawking prove?

Stephen Hawking, in full Stephen William Hawking, (born January 8, 1942, Oxford, Oxfordshire, England—died March 14, 2018, Cambridge, Cambridgeshire), English theoretical physicist whose theory of exploding black holes drew upon both relativity theory and quantum mechanics. He also worked with space-time singularities.
