In this episode, a question from listener Freddie - “What’s heavier, cold water or hot water?” - leads Lily and Lloyd into a discussion about why water is so important for life on Earth. 

With help from Elle Bethune from the UK Centre for Astrobiology, Lily explains how water’s weirdness helped life to form on our planet, and how it could help to create life on other planets in the universe.
