Documentary Description
Horizon’s Time Trip is a thrilling journey deep into the strangeness
of cutting-edge physics – a place where beautiful, baffling ideas are
sometimes indistinguishable from the utterly crazy.
On this journey, we meet a time-travelling pizza, a brilliant
mathematician in a ski mask and even God. The journey ends with a
strange and dark conclusion – one which calls into question our very
existence.
Ever since Einstein showed it was theoretically possible, the quest
to travel through time has drawn eccentric amateurs and brilliant
scientists in almost equal numbers. The amateurs include Aage Nost, who
demonstrates his time machine in front of the cameras. The
professionals include the likes of Professor Frank Tipler of Tulane
University. His time machine sounds good – but it would weigh half the
mass of the galaxy.
There is, however, one way that time travel to the past could be
possible. And it would be much more convenient. Future civilisations
could use computers to create exact replicas of the past. Unfortunately
that idea has physics trembling in its socks. Because if you can
generate a perfect virtual reality version of the past, who’s to say we
are not one of the replicas?
