Series 17, Episode 1 - When Two Stars Collide
The observation of this huge cosmic event not only confirmed one of Einstein's great predictions, some 100 years ago, but also revealed the source of gold in our universe. Brian, Robin and guests look at how this momentous discovery brought together nearly one-third of the world's astronomers and astrophysicists as they raced to point their telescopes at the collision, but also confirmed the presence of gravitational waves, first predicted in Einstein's theory of general relativity back in 1915. They also discover why the source of our heavier elements such as gold and platinum has been so difficult to prove, until now.
