Query: Computing Black Hole Entropy at Infinity   We show that the entropy of asymptotically flat, nonextremal black holes can
be computed at infinity. We provide a prescription for transforming these black
holes to $AdS_2$ black holes with the same entropy by dimensional reduction to
2D and a Weyl transformation. We apply our prescription to Schwarzschild, 4D
Reissner--Nordstrom and generic nonextremal black holes. In the transformed
coordinates, the asymptotic regions contain a global $AdS_2$ whose entropy can
be computed either as the holographic entanglement entropy or as the
entanglement entropy of a pair of Rindler $AdS_2$ spaces in the thermofield
double state. This precisely reproduces the entropy of the original nonextremal
black holes.
