How do you build a universe? Adam Hart-Davis is 100 metres underground with the team hoping to blast their way back to the Big Bang in the world's largest experiment. They are on the trail of tiny particles not seen since space and time began.

And there is a team from Scotland who make stomach-churning anti-gravity flights in an attempt to find out how the planets were formed.
