Astronomer Royal Martin Rees shows in this bite-sized science classic how the behaviour and origins of the universe can be explained by just six numbers. How did a single genesis event create billions of galaxies, black holes, stars and planets? How did atoms assemble - here on Earth and perhaps on other worlds - into living beings intricate enough to ponder their origins?
It's famously called the Final Frontier, and thanks to rapidly developing technology we now know more about the outer reaches of our galaxy than ever. But that leaves unknowns. Lord Martin Rees, speaking before a live audience at Melbourne University Melbourne, Australia, on March 30, 2010.
