The series explores the incredible universe inside each and every one of us. Through an examination of diverse personal stories from around the world, Human reveals how our everyday lives, our passions, and our goals are powered by the amazing systems that define our biology as a species.
The first episode goes on a journey with parents who are preparing for new life to see how our bodies create and sustain new life. Through their stories we learn about what is fundamentally shared and absolutely unique about the experience of birth.

Supermassive black holes are the engines that power our universe and one of the major players in the evolution of galaxies. They're in fact the driving force at the heart of nearly every galaxy in the cosmos. Now, a new mystery has emerged about the oldest supermassive black holes. We see supermassive black holes in the very early universe. And we don't understand how they grew so large so quickly. We have clues about their formation but, can we solve the mystery of this supermassive growth spurt?

The Earth was formed by a series of cosmic cataclysms including the most powerful blast in the Universe. Yet amid the turmoil our world was born. Could the same chain of events have created other earths elsewhere, inhabited by creatures like us?

And epic film by Adam Curtis that explains why the big stories that politicians tell us have become so simplified that we can’t really see the world any longer. The narrative goes all over the world, America, Britain, Russia and Saudi Arabia, but the country at the heart of it is Afghanistan. Because Afghanistan is the place that has confronted our politicians with the terrible truth, that they cannot understand what is going on any longer". The coumentary reveals the forces that over the past thirty years rose up and undermined the confidence of politics to understand the world. And it shows the strange, dark role that Saudi Arabia has played in this. But Bitter Lake is also experimental. Curtis has taken the unedited rushes of everything that the BBC has ever shot in Afghanistan - and used them in new and radical ways. He has tried to build a different and more emotional way of depicting what really happened in Afghanistan. A counterpoint to the thin, narrow and increasingly destructive stories told by those in power today.

The story of Tilikum, a captive killer whale that has taken the lives of several people , including a top killer whale trainer, underscores the consequences of keeping these powerful animals in captivity, the problems within the sea-park industry, the man's relationship to nature, and how little has been learned about these highly intelligent and sentient mammals.
Tilikum was captured in the northern Atlantic Ocean in 1983 and taken to Sealand of the Pacific, a now-shuttered park near Victoria, British Columbia. Former Sealand trainers interviewed in 'Blackfish' say the park’s female killer whales would aggressively gang up on Tilikum, particularly when they were confined in a 20-foot-by- 30-foot pool overnight.

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?
