Distinction between eternal and collapsing black holes is crucial

Local QFT in curved spacetime is essential for understanding effects

Clarifies the relation between Unruh and Hawking effects

Abstract

The present paper stress on the distinction between the two idealizations~-- eternal (primordial) black hole and a black hole formed in a process of gravitation collapse. Such a distinction is an essential condition for a better understanding of the relation between Unruh effect and Hawking effect. The fundamental character of the discussions inside requires a preferred orientation to results of the local QFT in curved space-time.
