How Analogue Gravity Lets Us Trap 'Black Hole' Light on a Tabletop
Researchers have simulated the light-trapping behaviour of black holes using tiny, 3D-printed optical cavities. By creating a physical model on a tabletop, they successfully measured how light behaves in a 'photon sphere', offering a safe way to study cosmic physics.
