Researchers have uncovered distinct quantum effects on radiation from a black hole caused by atoms plummeting into it. This intriguing black hole study may illuminate the ongoing quest to unify quantum mechanics and Einstein’s theory of relativity—two paramount scientific theories of the last century. The discovery expands our understanding of the principle of equivalence in a quantum scenario, an essential aspect of general relativity. This principle, articulated by Einstein, maintains that laws of nature are invariant, whether in the presence or absence of a gravitational field. Investigating atoms’ radiation falling into a quantum-corrected black hole, the team led by Dr. Sunandan Gangopadhyay from S.N. Bose National Centre for Basic Sciences found that the emitted “horizon brightened acceleration radiation entropy” (HBAR entropy) adhered to the area law, exhibiting unique characteristics providing insights into Einstein’s principle of equivalence.
