Gaia and the Killer Asteroids

Ever wondered where the Universe came from?  Or more importantly, where it's headed?  Voiced by David Mitchell, this series of 60 second animations examines different scientific concepts from the big bang to relativity, from black holes to dark matter.  The series also explores the possibility of life beyond Earth and considers why David Bowie is still none the wiser about life on Mars.
