July 26, 2024• Physics 17, 119The formation of a black hole from light alone is permitted by general relativity, but a new study says quantum physics rules it out. D. Coe, J. Anderson, and R. van der Marel/NASA/ESA/STScI D. Coe, J. Anderson, and R. van der Marel/NASA/ESA/STScI × Black holes are known to form from large concentrations of mass, such as burned-out stars. But according to general relativity, they can also form from ultra-intense light. Theorists have speculated about this idea for decades. However, calculations by a team of researchers now suggest that light-induced black holes are not possible after all because quantum-mechanical effects cause too much leakage of energy for...
