Scientists crack 50-year-old physics theory to create first-ever black hole bomb

Physicists in the UK have created the first lab version of a "black hole bomb," confirming a 50-year-old theory on energy extraction from rotating black holes. Using a spinning aluminum cylinder with magnetic coils, they replicated superradiance, observing energy amplification and spontaneous signal generation from background noise. This breakthrough could offer insights into black hole interactions and help test...
