PBS Space Time - Season 2020 Episode 19 Does Gravity Require Extra Dimensions?
10.00 48 minutes It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those secrets may be revealed by turning back to the Cavendish experiment. That steampunk contraption may even reveal the existence of extra dimensions of space.
