Stephen Hawking was a brilliant man. A man with a broken body and a world-class mind. He was responsible for the discovery of “Black Holes” and believed time travel may be possible. His book, “A Brief History of Time” was brilliant in the way it described complex theories in layman terms and if you have not read it we highly recommend it. Mr. Hawking’s time travel theory involves black holes, which is no surprise and you can find it HERE.
