Event horizon of a Schwarzschild black hole: magnifying glass for Planck length physics

摘要: An attempt is made to describe the ``thermodynamics'' of semiclassical spacetime without specifying detailed ``molecular structure'' quantum spacetime, using known properties black holes. I give arguments, essentially based on behavior systems near event horizon, which suggest that horizon a Schwarschild hole acts as magnifying glass probe Planck length physics even in those contexts curvature arbitrarily low. The state describing hole, any microscopic description has possess certain universal form density states can be ascertained from general considerations. Since formed collapse physical system with low energy Hamiltonian H, it suggested high should described by modified ${H}_{\mathrm{mod}}^{2}{=A}^{2}\mathrm{ln}{(1+H}^{2}{/A}^{2})$ where ${A}^{2}\ensuremath{\propto}{E}_{P}^{2}.$ also show possible construct several have and hence will indistinguishable far thermodynamic interactions are concerned. In particular, holes thought one-particle excitations class nonlocal field theories thermodynamics arising asymptotic dispersion relation satisfied these excitations. These theoretic models correlation functions short distance behavior, translates into generic Several implications this paradigm discussed.
