Imagine a world where infinite copies of you are playing out every storyline of your life. It sounds like a plot stolen straight from Hollywood, but far from it. This is the multiverse. Until very recently the whole idea of the multiverse was dismissed as a fantasy, but now this strangest of ideas is at the cutting edge of science. And for a growing number of scientists, the multiverse is the only way we will ever truly make sense of the world we are in. Do multiple universes exist? And if so, which one are we actually in?" Imagine a world where dinosaurs still walk the earth. A world where the Germans won World War II and you are president of the United States. Imagine a world where the laws of physics no longer apply.

Located in an almost inaccessible chamber deep in a South African cave, the site required recruiting a special team of experts slender enough to wriggle down a vertical, pitch-dark, seven-inch-wide passage. Most fossil discoveries of human relatives consist of just a handful of bones. But down in this hidden chamber, the team uncovered an unprecedented trove—so far, over 1,500 bones—with the potential to rewrite the story of our origins". They may help fill in a crucial gap in the fossil record and tell us how Homo, the first member of the human family, emerged from ape-like ancestors like the famous Lucy. But how did hundreds of bones end up in the remote chamber? The experts are considering every mind-boggling possibility. Join us on the treacherous descent into this cave of spectacular and enigmatic finds, and discover their startling implications for the saga of what made us human.

In an invisible territory at the margins of society lives a wounded community who face the threat of being forgotten by political institutions and having their rights as citizens trampled. Disarmed veterans, taciturn adolescents, drug addicts trying to escape addiction through love; ex-special forces soldiers still at war with the world; floundering young women and future mothers; and old people who have not lost their desire to live. Through this hidden pocket of humanity, renowned documentarian Roberto Minervini opens a window to the abyss of today's America.

Montezuma Dan Snow journeys to the ancient heart of Mexico in search of the lost civilisation of the Aztecs and their last and greatest ruler, Montezuma II (1502-1520). Montezuma inherited an empire of five million people, stretching from present-day Mexico to Nicaragua, from his uncle. His rule was marked by incessant warfare. Enemy states were growing more powerful and conquered tribes were becoming more rebellious. Within months of taking the throne in 1502, he went changed a man of good reason into a pitiless autocrat who declared himself a god, believing that fear and ruthlessness were the only ways to stop the empire falling apart. Yet it was at the hands of Cortes and the Spanish conquistadors that Montezuma met his downfall. But what was his relationship with Cortes, and why did such a ruthless leader submit to his captors with such relative ease? As Dan Snow visits the ruins and picks through current excavations, he pieces together the evidence of a gripping story: a divine tragedy of errors, the clash of civilisations, the end of a world - and a very human God.

Launched in 1982 by three friends in a Houston diner, Compaq Computer set out to build a portable PC to take on IBM, the world's most powerful tech company. Many had tried cloning the industry leader's code, only to be trounced by IBM and its high-priced lawyers. 'Silicon Cowboys' explores the remarkable David vs. Goliath story, and eventual demise, of Compaq, an unlikely upstart who altered the future of computing and helped shape the world as we know it today. Directed by Oscar (R)-nominated director Jason Cohen, the film offers a fresh look at the explosive rise of the 1980's PC industry and is a refreshing alternative to the familiar narratives of Jobs, Gates, and Zuckerberg.

We inhabit a cosmos of undiscovered dimensions and paradoxical realities. We live on one level of perception, but there are others. Every once in a while, a searcher happens upon the doorway to one of these other levels. One of them discovered a paradox about reality that proved to be so profound, we have yet to understand how it could be possible. The universe, or perhaps we should say, universes have never been the same.
In the counterintuitive realm of quantum mechanics, light can be two contradictory things, and somehow - no one knows how - an unseen observer can alter the nature of reality. The man who stumbled on this hole in reality and the still- unfolding technological revolution that it made possible.
