Stephen Hawking: "Time Travel to the Future is Possible"

Stephen Hawking: "Time Travel to the Future is Possible": "'I do believe in time travel. Time travel to the future. Time flows like a river and it seems as if each of us is carried relentlessly along by time's current. But time is like a river in another way. It flows at diff erent speeds in diff erent places and that is the key to travelling into the future. This idea was first proposed by Albert Einstein over 100 years ago.'
