NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination. This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything." Our guide to this brave new world is Brian Greene, the bestselling author and physicist. BRIAN GREENE (Columbia University) : And no matter how many times I come here, I never seem to get used to it.

Two main engines of ATV-3 were switched on at 1:54 Moscow time on Sunday [21:54 GMT on Saturday] to raise the International Space Station (ISS) orbit by 1.7 km, to 389.8 km. "Engines of Europe’s ATV-3 spacecraft remained switched on for 411 seconds (almost seven minutes), giving the ISS an additional acceleration of one meter per second,” the source said.
