What is gravity, really? Why do objects pull towards each other at all? And if Einstein 'fixed' Newton’s theory, why does gravity remain one of science’s biggest unsolved mysteries?
A clumsy trip into a lamppost leads Michael and Hannah into a whirlwind tour of our changing understanding of gravity, from falling apples and making wormholes for ants, to the puzzles we still can’t crack.
Why does time tick faster on a mountaintop than by the sea? Why are galaxies spinning in ways our equations can’t explain? And could an invisible particle finally reveal what gravity is made of?
Join Professor Hannah Fry and YouTube educator Michael Stevens as they uncover the strange, unfinished story of the force that holds the universe together.
