Black holes are the most enigmatic and exotic objects in the universe. They’re also the most powerful; with gravity so strong it can trap light. And they’re destructive, swallowing entire planets, even giant stars. Anything that falls into them vanishes... gone forever. Now, astrophysicists are realizing that black holes may be essential to how our universe evolved—their influence possibly leading to life on Earth and, ultimately, us.
In this series, astrophysicist and author Janna Levin takes viewers on a journey to the frontiers of black hole science. Along the way, we meet leading astronomers and physicists on the verge of finding new answers to provocative questions about these shadowy monsters: Where do they come from? What’s inside? What happens if you fall into one? And what can they tell us about the nature of space, time, and gravity?

David Attenborough and the world-renowned scientist Johan Rockström examine Earth's biodiversity collapse. The film explains how humanity has pushed our planet beyond the boundaries that have kept it stable since the dawn of life, but also that this crisis can still be averted, thinking and acting with one unified purpose to ensure that Earth forever remains healthy and resilient.

Mammals' ability to learn new tricks is the key to survival in the knife-edge world of hunters and hunted. In a TV first, a killer whale off the Falklands does something unique: it sneaks into a pool where elephant seal pups learn to swim and snatches them, saving itself the trouble of hunting in the open sea. Slow-motion cameras reveal the star-nosed mole's newly-discovered technique for smelling prey underwater: it exhales then inhales a bubble of air ten times per second. Young ibex soon learn the only way to escape a fox - run up an almost vertical cliff face - and young stoats fight mock battles, learning the skills that make them one of the world's most efficient predators.

Fish dominate the planet's waters through their astonishing variety of shape and behaviour. The beautiful weedy sea dragon looks like a creature from a fairytale, and the male protects their eggs by carrying them on his tail for months. The sarcastic fringehead, meanwhile, appears to turn its head inside out when it fights. Slow-motion cameras show the flying fish gliding through the air like a flock of birds and capture the world's fastest swimmer, the sailfish, plucking sardines from a shoal at 70 mph. And the tiny Hawaiian goby undertakes one of nature's most daunting journeys, climbing a massive waterfall to find safe pools for breeding.

Dan Cohen, founder of the nonprofit organization Music & Memory, fights against a broken healthcare system to demonstrate music's ability to combat memory loss and restore a deep sense of self to those suffering from it.

The series about the man, myth and legend - founder of Microsoft and co-founder of the Bill and Melinda Gates Foundation - reflects on his trailblazing work with computer software, starting the largest private philanthropic foundation. Bill Gates opens up about his childhood, business career and passion for improving the lives of people in the developing world.
When Bill Gates stepped down from Microsoft in 2008, he was worth more than 58 billion dollars. He built that fortune thinking about computer software, operating systems, spreadsheets and the Internet. What was on his mind?
