What are the origins of life? How did things go from non-living to living? From something that could not reproduce to something that could? Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one form or another. Our planet is teaming with life, from the highest mountain to the deepest ocean; life is everywhere. But what was the firing pistol that started the evolutionary race? How did material go from non-living to alive? It's one of the most fundamental and difficult questions that has challenged us since the beginning of time.

In a powerful conclusion, Brian pieces together this story of creation that started with what Einstein called the 'happiest thought of his life' - the moment that he realised that gravity was far stranger than anyone had imagined. In an incredible experiment inside the largest vacuum chamber, Brian reveals how Einstein formulated a new theory of gravity, which ultimately took us back to the big bang. And how in doing so, we humans found our true place in space and time.

Are we in fact living in a simulation? This is the question postulated, wrestled with, and ultimately argued for in the latest provocation from acclaimed documentary stylist Rodney Ascher (Room 237, The Nightmare) through archival footage, compelling interviews with real people shrouded in digital avatars, and a collection of cases from some of our most iconoclastic figures in contemporary culture.

We have a relationship with few things in nature the way we do with snow: we hate it, we love it, and we think we understand it. But we barely know the contradictory and beautiful components of snow’s character. But that’s something scientists are changing. From the formation of single flakes to the howling 70 km/h winds of lake effect snow storms to the destructive power of avalanches, intrepid researchers are bringing snow science into the 21st Century.

Dr Alice Roberts asks one of the great questions about our species: are we still evolving? There's no doubt that we're a product of millions of years of evolution. But thanks to modern technology and medicine, did we escape Darwin's law of the survival of the fittest? Alice follows a trail of clues from ancient human bones to studies of remarkable people living in the most inhospitable parts of the planet and the frontiers of genetic research, to discover if we are still evolving - and where we might be heading.
