In households across the world, pets are at the heart of family life. They share our homes, but how well do we really know them? In this series we'll dig deep into our pets' inner lives to discover the secrets they've kept hidden until now. From spectacular feats of communication to extreme athleticism, extraordinary intelligence and incredible super senses.
We'll meet remarkable pets from across the globe whose owners have harnessed their hidden skills and shared them with the world and will use groundbreaking technology to reveal how amazing their brains and bodies really are.
In the first episode, a base-jumping border collie, a bopping cockatoo, and racing rats show that animal intelligence can get a big boost in the right enriched environment.

The International Space Station is the ultimate extreme home. Costing $150 billion, it is the most expensive structure humans have ever built, in the most inhospitable environment known to man, with no air food or water. Assembled at 250 miles above the earth, it's an epic engineering challenge. We're going to take it apart and uncover what's going on inside the ISS.
Its superstructure secrets will help our species reach other planets and beyond. Using photo-real computer graphics, we take it apart to uncover the extraordinary innovations that enable it to support life in the deadly vacuum of space.

The most innovative area of human motion lies not on Earth, but with the exploration of space. Space is the most hostile environment we know. Navigating it involves crossing unprecedented distances. It's the greatest engineering challenge humanity has ever undertaken.
Meet the pioneers who've dreamed of reaching other worlds, pushing the boundaries of space exploration, and the private space entrepreneurs jostling to offer the tantalizing prospect of cheap, frequent travel beyond the atmosphere into Earth orbit.

25 years ago, NASA launched one of the most ambitious experiments in the history of astronomy: the Hubble Space Telescope. In honor of Hubble's landmark anniversary, know the remarkable story of the telescope that forever changed our understanding of the cosmos and our place in it". But amazingly, when the telescope first sent images back to earth, it seemed that the entire project was a massive failure; a one-millimeter engineering blunder had turned the billion-dollar telescope into an object of ridicule. It fell to five heroic astronauts in a daring mission to return Hubble to the cutting edge of science. Hear from the scientists and engineers on the front line who tell the amazing Hubble story as never before. This single telescope has helped astronomers pinpoint the age of the universe, revealed the birthplace of stars and planets, advanced our understanding of dark energy and cosmic expansion, and uncovered black holes lurking at the heart of galaxies. For more than a generation, Hubble's stunning images have brought the beauty of the heavens to millions, revealing a cosmos richer and more wondrous than we ever imagined. Join us for the story of this magnificent machine and its astonishing discoveries.

We live under a billion unblinking eyes - a global surveillance system that solves crime and uncovers terrorist plots. But are we ready for a world without secrets - where not even our homes are off-limits and corporations know our every desire?

Shocking new evidence has convinced some of the world's greatest physicists that the universe is a hologram. Using cutting-edge technology, they investigate the secrets of black holes and space-time to build the case for this game-changing discovery.
The holographic principle is a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region like a gravitational horizon. First proposed by Gerard 't Hooft, it was given a precise string-theory interpretation by Leonard Susskind.
The holographic principle was inspired by black hole thermodynamics, which conjectures that the maximal entropy in any region scales with the radius squared, and not cubed as might be expected. In the case of a black hole, the insight was that the informational content of all the objects that have fallen into the hole might be entirely contained in surface fluctuations of the event horizon.
