It has been shown that the quantum state of the graviton field outside a black hole horizon carries information about the internal state of the hole. We explain how this allows unitary evaporation: the final radiation state is a complex superposition which depends linearly on the initial black hole state. Under time reversal, the radiation state evolves back to the original black hole quantum state. Formulations of the information paradox on a fixed semiclassical geometry describe only a small subset of the evaporation Hilbert space, and do not exclude overall unitarity.

  1. The old problem of the cosmological constant solved?

    gr-qc 2025-05 reject novelty 4.0 of 10

    A speculative essay claims that a model of gravity as superluminal phonons on a ring lattice solves the cosmological constant problem, but provides no derivation of the values or dynamics.
