BBC - Horizon - What on earth is wrong with gravity?
Do you know what lies at the bottom of the ocean? Representing the majority of our planet's surface, extreme pressure and perpetual darkness mean that the ocean depths have only been seen by torchlight - until now. From the makers of the Walking with... series comes an enthralling exploration of Earth's final frontier seen through the eyes of its greatest inhabitant and the world's largest predator, the sperm whale. Following a young male from infancy to old age, the marinescape comes vividly to life: the impossibly deep canyons, the underwater volcanoes, and the spectacular mountain ranges.
Check out http://www.documentarywire.com For fifty years, the Search for Extra Terrestrial Intelligence has been scanning the galaxy for a message from an alien civilisation. So far to no avail, but a recent breakthrough suggests they may one day succeed. Horizon joins the planet hunters who've discovered a new world called Gliese 581 c. It is the most Earth-like planet yet found around another star and may have habitats capable of supporting life. NASA too hopes to find fifty more Earth-like planets by the end of the decade, all of which dramatically increases the chance that alien life has begun elsewhere in the galaxy.

The secret of sex Before science put it under microscope, sex was a simple, uncomplicated thing. You could not build humans without it. All you needed was a man, a woman, a liberal sprinkling of lust and Mother Nature did the rest. But is that now a terribly old-fashioned way of making new human? In the future we’ll able to build humans in tanks, make copies of ourselves in labs and even have the power to change the course of our genetic destiny by turning women into men. If kissing is nothing more than a way of sniffing out compatible genes, what is the point of sex, and will it ever be the same again?

BBC Horizon: The Day We Learned to Think
Exploring the possibility of extraterrestrial life in the Universe. Note: When downloading, for Sound to work you need AC3 filter.
Everything you're about to read here seems impossible and insane, beyond science fiction. Yet it's all true. Scientists now believe there may really be a parallel universe - in fact, there may be an infinite number of parallel universes, and we just happen to live in one of them. These other universes contain space, time and strange forms of exotic matter. Some of them may even contain you, in a slightly different form. Astonishingly, scientists believe that these parallel universes exist less than one millimetre away from us. In fact, our gravity is just a weak signal leaking out of another universe into ours.
For twenty years scientists have been studying the aftermath of the Chernobyl disaster for people and wildlife. What they have found contradicts many common beliefs about the effects of radiation. As this film reveals, leading scientists are now questioning the assumptions that have for decades governed their thinking about the dangers of radiation.

Particle physicist Professor Brian Cox asks, 'What time is it?' It's a simple question and it sounds like it has a simple answer. But do we really know what it is that we're asking? Brian visits the ancient Mayan pyramids in Mexico where the Maya built temples to time. He finds out that a day is never 24 hours and meets Earth's very own Director of Time. He journeys to the beginning of time, and goes beyond within the realms of string theory, and explores the very limit of time. He discovers that we not only travel through time at the speed of light, but the experience we feel as the passing of time could be an illusion.
