Black Holes, Wormholes, and Time Machines
by Jim Al-Khalili
Do you know:
•What might happen if you fall into a black hole?
•That the Universe does not have an edge?
•That the reason it gets dark at night is proof of the Big Bang?
•That cosmic particles time-travel through the atmosphere defying death?
•That our past, present, and future might all coexist "out there"?
With two remarkable ideas, Albert Einstein revolutionized our view of the Universe. 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.
