Shrinking black holes avoid paradox by oozing hidden information

                                                  Leaking hidden information



The random disorder of subatomic particles – their entropy – might be the key to solving a long-standing puzzle about how black holes lose information. This proposal could help unite gravity and quantum mechanics. “Quantum gravity nowadays is really far beyond our limits,” says Ana Alonso-Serrano at the Max Planck Institute for Gravitational Physics in Golm, Germany. “But I think black holes are a good arena to test it.” Black holes are both a blessing and a curse to researchers because their huge mass is compressed down to a tiny point, meaning they are simultaneously governed by the two pillars of physics – general relativity, which deals with the very large, and quantum mechanics, which focuses on the very small. Yet trying to combine these frameworks has often led to trouble. According to quantum mechanics, information about a particle can’t be destroyed. But material that falls.
