Quantum effects forbid the formation of black holes from high concentrations of intense light, say physicists
Credit: NASA For the last seven decades, astrophysicists have theorized the existence of “kugelblitze,” black holes caused by extremely high concentrations of light. These special black holes, they speculated, might…
