A Brief History of Time is a book by the famous British physicist Stephen Hawking, providing a non-technical overview of various cosmological topics. Although Hawking explains and summarizes complex mathematics and does not print most of the equations its theories postulate, the book explains the evolution of the universe from the Big Bang and delves into topics concerning gravitation such as black holes. Hawking also discusses models of the universe that would allow for time travel and wormholes.
