This book presents a comprehensive review of the subject of gravitational effects in quantum
field theory. Although the treatment is general, special emphasis is given to the Hawking …

The 100 years since the publication of Albert Einstein's theory of general relativity saw
significant development of the understanding of the theory, the identification of potential …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

In the classical theory black holes can only absorb and not emit particles. However it is
shown that quantum mechanical effects cause black holes to create and emit particles as if …

First published in 1973, this influential work discusses Einstein's General Theory of Relativity
to show how two of its predictions arise: first, that the ultimate fate of many massive stars is to …

For many decades, the proponents of artificial intelligence'have maintained that computers
will soon be able to do everything that a human can do. In his bestselling work of popular …

One can evaluate the action for a gravitational field on a section of the complexified
spacetime which avoids the singularities. In this manner we obtain finite, purely imaginary …

Stars whose masses are of the same order as that of the Sun (M.) can find a final equilibrium
state either as a white dwarf or, apparently,(after collapse and ejection of material) as a …

The principle of equivalence, which says that gravity couples to the energy-momentum
tensor of matter, and the quantum-mechanical requirement that energy should be positive …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …
