"With two remarkable ideas Albert Einstein revolutionized our view of the Universe. His first was that nothing travels faster than light - the ultimate speed limit. This simple fact leads to the unavoidable conclusion that space and time must be linked together, forever, as Spacetime." "With his second monumental insight Einstein showed how Spacetime is warped and stretched by the gravity of all objects in the Universe and even punctured by black holes. But, such possible twisting of Spacetime allowed a magic not even Einstein could have imagined: time travel." "Theoretical physicist Jim Al-Khalili finally lays science fiction to rest as he opens up Einstein's Universe. Leading us gently and light-heartedly through the dizzying world of our space and time, he even gives us the recipe for a time machine capable of taking us Back to the Future, to Alice's Wonderland or on a trip with the Terminator."--BOOK JACKET.
