Stephen Hawking is the most famous scientist on the planet. But behind the public face lies an argument that has been raging for almost 30 years. Has he been wrong for the last 30 years? Hawking shot to fame in the world of physics when he provided a mathematical proof for the Big Bang theory. This theory showed that the entire universe exploded from a singularity, an infinitely small point with infinite density and infinite gravity. Hawking was able to come to his proof using mathematical techniques that had been developed by Roger Penrose. These techniques were however developed to deal not with the beginning of the Universe but with black holes". Science had long predicted that if a sufficiently large star collapsed at the end of its life, all the matter left in the star would be crushed into an infinitely small point with infinite gravity and infinite density – a singularity. Hawking realised that the Universe was, in effect, a black hole in reverse. Instead of matter being crushed into a singularity, the Universe began when a singularity expanded to form everything we see around us today, from stars to planets to people. Hawking realised that to come to a complete understanding of the Universe he would have to unravel the mysteries of the black hole and its paradoxes

What triggered the incredible diversity of life on Earth, and how have complex life forms, including humans, evolved? Is there direction to evolution? And is human intelligence inevitable? This program focuses on evolution's 'great transformations' —among them the development of a standard four-limbed body plan, the journey from water to land, the return of marine mammals to the sea, and the emergence of humans. Driven by a combination of opportunism and a genetic 'toolkit', these astounding leaps forward define the arc of evolution. And they suggest that every living creature on earth today, and every species that has ever existed, is a variation on a grand genetic theme—a member of one, and only one, tree of life

Comedian Ben Miller returns to his roots as a physicist to try to answer a deceptively simple question: what is one degree of temperature? His quest takes him to the frontiers of current science as he meets researchers working on the hottest and coldest temperatures in the universe, and to a lab where he experiences some of the strangest effects of quantum physics - a place where super-cooled liquids simply pass through solid glass. Plus, Ben installs his very own Met office weather station at home. Ben's investigations in this personal and passionate film highlight the importance of measurement and accuracy in the 21st century.

If you're a paleontology buff, this series is for you. And the fun-loving Nigel Marvin provides a great narrative. Explore the prehistoric world in search of sea-based monsters. It focuses on life in ancient oceans during each prehistoric period. Nothing, not the carnivorous dinosaurs of the past, nor the imagined sea serpents and monsters of maritime history, nor the great white shark, salt water crocodile, killer whale and leopard seal of today can compare to the horrifying hunters of the prehistoric oceans.

Embark on an astounding journey across 100,000 light-years to witness key moments in the history of the Milky Way. Using cutting-edge science, National Geographic constructs a 3-D state-of-the-art CGI model of our galaxy. We'll peer into the heart of the Milky Way on the hunt for super-massive black holes, watch how stars are born and die, fly out and above the plane of our galaxy to understand its true shape and scour its dusty spiral arms for the possibility of life

Be prepared to fight your way past all kinds of computer animation. Somehow Patrick Moore's The Sky at Night manages to convey just as much excitement with little more than a couple of diagrams and the presenter's hyperactive enthusiasm. The series cover the history of the solar system and humanity's age-old desire to learn its secrets. Far beyond the inner planets of rock and iron lie the gas giants. Discover the most distant and alien worlds in our Solar System and the moment of genius that allowed scientists to explore them.
