Abstract: | While extreme black hole spacetimes with smooth horizons are known at the level of mathematics, we argue that the horizons
of physical extreme black holes are effectively singular. Test particles encounter a singularity the moment they cross the
horizon, and only objects with significant back-reaction can fall across a smooth (now non-extreme) horizon. As a result,
classical interior solutions for extreme black holes are theoretical fictions that need not be reproduced by any quantum mechanical
model. This observation suggests that significant quantum effects might be visible outside extreme or nearly extreme black
holes. It also suggests that the microphysics of such black holes may be very different from that of their Schwarzschild cousins. |
