According to the laws of physics we can never travel faster than the speed of light...or can we? Learn all about light speed, the ultimate constant in the universe.

For centuries, the precise workings of gravity have confounded the greatest scientific minds - from Newton to Faraday and Einstein - and the idea of controlling gravity has been seen as little more than a fanciful dream. Yet in the mid 1990s, UK defence manufacturer BAE Systems began a ground-breaking project code-named Greenglow. Nasa was simultaneously running its own Breakthrough Propulsion Physics Project". It was concerned with potential space applications of new physics, including concepts like 'faster-than-light travel' and 'warp drives'. Looking into the past and projecting into the future, Horizon explores science's long-standing obsession with the idea of gravity control. It looks at recent breakthroughs in the search for loopholes in conventional physics and examines how the groundwork carried out by Project Greenglow has helped change our understanding of the universe. Gravity control may sound like science fiction, but the research that began with Project Greenglow is very much ongoing, and the dream of flying cars and journeys to the stars no longer seems quite so distant.

Focuses on the fierce rivalry that took place in the laboratories in Britain, Holland, France and Poland as they sought the ultimate extreme of cold. The program will follow the extraordinary discoveries of superconductivity and superfluidity and the attempt to produce a new form of matter that Albert Einstein predicted would exist within a few billionths of degrees above absolute zero.

Could time travel ever be science fact? Time itself may be something you can bend and stretch. Trying to understand if time travel can be possible teach us a lot about the universe. It forces us to take on some of the toughest unanswered questions in all of physics and will ultimately probably lead to deeper understanding of the very nature of the cosmos.

The film looks at the latest understanding of black holes, featuring an interview with Stephen Hawking. Black holes are one of the greatest mysteries in the universe. They behave in a way that is contrary to laws of physics and one has never actually been seen. However, the recent detection of gravitational waves, as predicted by Einstein, proves that black holes exist and provides a way to investigate their remarkable behaviour and properties.

This new feature-length biographical film tells the extraordinary and dramatic story of the planet's most famous living scientist, told for the first time in his own words and by those closest to him. Made with unique access to his private life, this is an intimate and moving journey into Stephen Hawking's past and present. Interviewees include Stephen Hawking's sister Mary, his ex-wife Jane, carers and students, as well as colleagues such as Roger Penrose, plus Apollo astronaut Buzz Aldrin, actors Benedict Cumberbatch and Jim Carrey, and Sir Richard Branson This inspirational portrait of an iconic figure relates Hawking's incredible personal journey from boyhood underachiever to scientific genius and multi-million-selling author. And it charts how he overcame being diagnosed with motor neurone disease - and being given just two years to live - to make amazing scientific discoveries and become a symbol of triumph over adversity. Born exactly 300 years after the death of Galileo, Hawking grew up in a family some regarded as eccentric. Always asking questions, he was nicknamed 'Einstein' at school. Hawking blossomed at Oxford, although he only spent an hour a day studying. He noticed that he was becoming clumsy and fell over for no apparent reason. He was diagnosed with motor neurone disease, but nevertheless started a family and embarked on his academic career, finding himself at the heart of a searing scientific debate about the origins of the universe. And as he lost the use of his body, Hawking had to find new ways to think. He went on to write the huge bestseller A Brief History of Time, and the film reveals the high and lows of his resulting fame and fortune.
