Question

How does one combine the basis of Quantum Physics that the information cannot be destroyed with the GR statement that black holes destroy the info?​

Answer 1

Answer

• Then two black holes collide head on and destroy each other into elementary particles, physics starts outside black holes again. So information show up again. The preserved quantity is energy. Therefore in black holes, the energy is preserved in their own physics principles. Information is the energy and the related physics principles inside black holes that the energy obey. The physics we know doesn’t work inside black holes. The principle for black holes is there, but is not known to human.

Answer 2

The preserved quantity is energy. Therefore in black holes, the energy is preserved in their own physics principles. ... I agree that the unitary evolution is a fundamental principle of QM, which you may translate as "Quantum Information cannot be neither destroyed nor created".
