Abstract This chapter gives a brief description of Hawking radiation, which involves a combination of general relativity and quantum field theory and leads to a thermodynamical interpretation of the laws governing the evolution of black holes.

Quantum Physics of Black Holes
1998Quantum radiation from an isolated black hole reduces its mass, and hence its surface area. This “violation” of Hawking’s area theorem is explained by drawing the inevitable conclusion that the particle flux to infinity which carries away positive energy is accompanied by a flux of negative energy across the horizon into the black hole.

Black holes and Newtonian physics
General Relativity and Gravitation, 1992It is argued that one-way passage is inconsistent with Newtonian physics and thus the dark bodies as thought of by Michell and Laplace cannot be considered as exact analogues of relativistic black holes.

Do Black Holes Physically Exist?
Annalen der Physik, 1984AbstractIt is shown that, if the quantum resolution limit in the region of a collapsing body near the horizon is of the order of the Schwarzschild radius, a black hole in vacuum evaporates away instantaneously; hence white and black holes ought to be physically indistinguishable and should not physically exist.

Introduction to Black Hole Physics
Classical and Quantum Gravity, 2012Introduction to Black Hole Physics is a large volume (504 pages), and yet despite this it is still really an introductory text. The book gives an introduction to general relativity, but most of the text is dedicated to attracting the reader's attention to the interesting world of black hole physics.

Black holes and everyday physics
General Relativity and Gravitation, 1982Black holes have piqued much curiosity. But thus far they have been important only in “remote” subjects like astrophysics and quantum gravity. We show that the situation can be improved. By a judicious application of black hole physics, one can obtain new results in “everyday physics.” For example, black holes yield a quantum universal upper bound on ...

Black Holes: Physics and Astrophysics
2006I present an elementary primer of black hole physics, including its general relativity basis, all peppered with astrophysical illustrations. Following a brief review of the process stellar collapse to a black hole, I discuss the gravitational redshift, particle trajectories in gravitational fields, the Schwarzschild and Kerr solutions to Einstein’s ...

On the Black Hole Internal Physics
Annalen der Physik, 1986AbstractField‐theory arguments are given in favour of a quantum resolution limit Δx ≳ GM in the region occupied by a black hole of mass M. A hierarchical formation of black holes inside a black hole is suggested and some reasons supporting the picture that a black hole is nothing but an “excited state of vacuum” are advanced.
