trailBlack holes emit Hawking radiation.
TeV-scale black holes produced at the LHC pose no significant risk.
Microscopic black holes evaporate almost instantaneously via Hawking radiation.
A metastable black hole accreting matter at the Eddington limit would emit hazardous Hawking radiation.
Theoretical derivation· for
Quantum field theory in curved spacetime predicts thermal radiation from black hole event horizons.
Hawking's semiclassical calculation shows gravitational collapse produces steady thermal emission at temperature proportional to horizon surface gravity
Hawking's original derivation traces outgoing modes back to frequencies far above the Planck scale.
Alternative derivations of Hawking radiation avoid appealing to trans-Planckian frequencies.
Modified trans-Planckian dispersion relations in black-hole models preserve the thermal spectrum at the Hawking temperature.
Independent theoretical derivations converge on the same black hole temperature.
atomic
Analogue-gravity evidence· for
Analogue Hawking radiation has been observed in laboratory systems.
shared · shown elsewhere
Empirical and foundational gaps· against
Hawking radiation has never been directly observed from an astrophysical black hole.
atomic
The derivation of Hawking radiation depends on unknown trans-Planckian physics.
The predicted Hawking spectrum is insensitive to modifications of trans-Planckian dispersion relations.
