Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up. The effects of dark energy were discovered in 1998 but physicists still don't know what it is. Worse, its very existence calls into question Albert Einstein's general theory of relativity - the cornerstone of modern physics. The hunt for the identity of dark energy is on. Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge - someone who can write a new theory explaining the mystery of the dark energy.

Time travel is not forbidden by the laws of nature, but to build a time machine, we would need to understand more about those laws and how to subvert them than we do now. And every day, science does learn more. In this film Horizon meets the scientists working on the cutting edge of discovery - men and women who may discover how to build wormholes, manipulate entangled photons or build fully functioning time crystals. In short, these scientists may enable an engineer of the future to do what we have so far been only able to imagine - to build a machine that allows us travel back and forward in time at the touch of a button. It could be you! Science fiction?

This two-part scientific detective tale tells the story of a remarkable group of pioneers who wanted to reach the ultimate extreme: absolute zero, a place so cold that the physical world as we know it doesn't exist, electricity flows without resistance, fluids defy gravity and the speed of light can be reduced to 38 miles per hour. Each film features a strange cast of eccentric characters, including: Clarence Birds Eye; Frederic 'Ice King' Tudor, who founded an empire harvesting ice; and James Dewar, who almost drove himself crazy by trying to liquefy hydrogen. Absolute zero became the Holy Grail of temperature physicists and is considered the gateway to many new technologies, such as nano-construction, neurological networks and quantum computing. The possibilities, it seems, are limitless. Part 2: Race for Absolute Zero 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.

You exist. You shouldn’t. Stars and galaxies and planets exist. They shouldn’t. The nascent universe contained equal parts matter and antimatter that should have instantly obliterated each other, turning the Big Bang into the Big Fizzle. And yet, here we are: flesh, blood, stars, moons, sky. Why? Come join us as we dive deep down the rabbit hole of solving the mystery of the missing antimatter.

The crosshairs are lined up, a death ray is fired and a planet is vaporized. Sci fi fantasy? Not according to Dr Michio Kaku, who draws up blueprints to show how a real death star might work. The technology could be here sooner than you think!
