EDITORIAL INFORMATION

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 revolutionised our view of the Universe. His first was that nothing can travel 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 streched 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 dyzzing world of our space and time, he ultimately gives us the recipe for a possible time machine, capable of taking us Back to the Future, to Alice's Wonderland or on a trip with the Terminator.
