Time Trip (BBC Horizon)

Time Trip is a BBC documentary exploring scientific ideas about the nature of time, in particular featuring our attempt to find a way to travel through time. It 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 civilizations 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?

Faster Than the Speed of Light?

In September 2011, an international group of scientists has made an astonishing claim - they have detected particles that seemed to travel faster than the speed of light. It was a claim that contradicted more than a hundred years of scientific orthodoxy. Suddenly there was talk of all kinds of bizarre concepts, from time travel to parallel universes. So what is going on? Has Einstein's famous theory of relativity finally met its match? Will we one day be able to travel into the past or even into another universe?

In this film, Professor Marcus du Sautoy explores one of the most dramatic scientific announcements for a generation. In clear, simple language he tells the story of the science we thought we knew, how it is being challenged, and why it matters.

Einstein’s Relativity and Quantum Revolution

Einstein’s Relativity and Quantum Revolution: Modern Physics for Non-Scientists taught by Professor Richard Wolfson consists of twenty-four lectures, demystifying the two key ideas of modern physics - Einstein’s theory of relativity and quantum physics. Relativity and quantum physics are not only profound and beautiful ideas in their own right, but they are also the gateway to understanding many of the latest science stories in the media, including time travel, string theory, black holes and particle accelerators.
