Time is flying by on this busy, crowded planet... as life changes and evolves from second to second.

Pandora is the idyllic blue world featured in the movie Avatar. Its location is a real place: Alpha Centauri, the nearest star to our Sun and the most likely destination for our first journey beyond the solar system. 

Remarkably, it's anti-matter, the science fiction fuel of choice that could take us there. Normally, it's only created in powerful jets that roar out of black holes. We can now produce small quantities in Earth-bound particle colliders. Will we journey out only to plunder other worlds? Or will we come in peace?

The year is 2154. Our planet has been ruined by environmental catastrophe. In the movie Avatar, greedy prospectors from Earth descend on the world of an innocent hunter-gatherer people called the Na'vi.
