Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science. The soap bubble with its delicate, fragile skin tells us about how nature works on scales as large as solar system and as small as a single wavelength of light. Then there are underwater bubbles, which matter because they are part of the how the planet works. Out at sea, breaking waves generate huge plumes of bubbles which help the oceans breathe. From the way animals behave to the way drinks taste, Dr Czerski shows how bubbles affect our world in all sorts of unexpected ways. Whether it's the future of ship design or innovative new forms of medical treatment, bubbles play a vital role.

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.
A war has been raging for billions of years, killing trillions every single day, while we don’t even notice. This war involves the single deadliest being on our planet: The Bacteriophage.
