How to Detect Extra Dimensions
PBS Space Time
A PBS Space Time episode on how gravitational wave observations of a neutron star merger, GW170817, can limit the number of spacetime dimensions. It is based on a 2018 paper.
HN points to it as a clear explanation of the evidence that gravity does not propagate into extra dimensions.
