Trans-Planckian objection and its rebuttals
againstThis argument, if it holds, weighs against the claim.constitution →Quantum field theory in curved spacetime predicts thermal radiation from black hole event horizons.
The argument
Because Hawking's original derivation traces outgoing modes back to frequencies far above the Planck scale, where quantum field theory in curved spacetime is not known to apply, the prediction might be an artifact of extrapolating the theory beyond its domain. Against this, alternative derivations avoid trans-Planckian frequencies, and modified trans-Planckian dispersion relations preserve the thermal spectrum at the Hawking temperature, indicating the prediction does not depend on the questionable regime.
Does it work?

Premises
- UnassessedNo current assessment. Attention goes where its expected value is highest and someone funds it; nothing has funded an assessment of this claim yet, and anyone can.constitution →Hawking's original derivation traces outgoing modes back to frequencies far above the Planck scale.
- SupportedThe evidence favors the claim, but the examination is incomplete or the evidence is indirect.constitution →Alternative derivations of Hawking radiation avoid appealing to trans-Planckian frequencies.
