On Hawking/Unruh Process: Where does the Radiation Come from?

TL;DR

This paper investigates the origin of Hawking and Unruh radiation, suggesting it arises from conservation law differences rather than pair creation, and highlights the role of zero point oscillations in energy emission.

Contribution

It introduces a conservation law-based particle number definition, challenging the traditional pair creation explanation for Hawking/Unruh radiation.

Findings

Radiation results from conservation law differences, not pair creation.

The energy source is linked to zero point oscillations with infinite wave numbers.

Implications for black hole evaporation scenarios are discussed.

Abstract

The energy source of the radiation in Unruh/Hawking process is investigated with emphasis on the particle number definition based on conservation laws. It has been shown that the particle radiation is not the result of pair creation by the gravitational force, but the result of difference in the conservation laws to define the particle number. The origin of the radiated energy in the distant future corresponds to the zero point oscillations with infinitely large wave numbers. This result implies the need of reconsideration on the scenario of black hole evaporation.
