This episode is a weighty one. Some might say massive. It’s all about gravity. What is it? Why does it matter? Izzie and Dr Becky explore Einstein and Newton’s different ideas on the subject, plus Izzie visits the Royal Society to see Isaac Newton's original manuscript for his works on gravity and the laws of motion.

Special thank you to listener Hanna_m_e for suggesting this episode topic and to Professor Tessa Baker, at the Institute of Cosmology and Gravitation at the University of Portsmouth, and to Keith Moore, head of collections at the Royal Society for appearing on the show.
