Gravity, space-time, the theory of relativity - how the universe works

AstroNuclPhysics ® Nuclear Physics - Astrophysics - Cosmology


The book introduces a wide range of issues related to the general theory of relativity as the physics of gravity, spacetime and the laws of origin, construction and evolution of the universe and cosmic bodies.

After an initial analysis of the relationship between gravity and other physics, especially electromagnetism and special theory of relativity (in classical vector and four-dimensional tensor formulation), Einstein's general theory of relativity is discussed in detail - consequences of equivalence, physical laws in curved spacetime, gravitational field equations, specific properties. gravitational energy, origin and propagation of gravitational waves.

The chapter on geometry and topology of space-time analyzes the properties of some significant solutions of Einstein's equations, causality and global structure of space-time, horizons, asymptotic properties of different types of infinity, geometric-topological tunnels and possibilities of multiple universes, the problem of space-time singularities and other issues important to space properties. and black holes.

Then the physics of black holes is discussed in detail as the most extreme manifestation of gravitational properties - evolution of stars and gravitational collapse, black holes of static Schwarzschild and rotating Kerov-Newman, exotic phenomena around black holes, laws of dynamics and thermodynamics of black holes, quantum evaporation of black holes, astrophysical significance. black holes.

The last chapter is devoted to the relationship between gravity and the global structure of the universe - relativistic cosmology. In addition to relativistic cosmological solutions and the standard model of the universe, the relationships between microphysics and cosmology, inflationary expansion, the anthropogenic principle and the possibilities of the existence of more universes are also discussed.

Finally, the two appendices briefly discuss Mach's principle, the quantization of the gravitational field, and the problems of unitary field theories.

Most of the questions discussed in this book have not yet been written in czech literature, either at all or only very briefly. The main goal of this monograph is to show readers how interesting and fundamental force gravity is, how deep its connections are with the properties of space-time and the structure of the universe, and where to look for the nature and origin of gravity.

In many places, the physical-mathematical interpretation is enlivened by passages discussing the gnoseological, philosophical and general-scientific aspects of relevant theories and knowledge - questions of infinity, cognition, determinism and chance or chaos, time travel, many universes, perspectives of life in space ...

The book "Gravity, Black Holes and the Physics of Spacetime" is intended primarily for physicists working in various fields, astronomers, lecturers, students and all those more seriously interested in the theory of relativity, gravity, astrophysics, cosmology and the fundamental laws of nature.

Author's apology:
The book was created at a time when there were no text editors yet and electronic form of information. The manuscript was transcribed into typescript, which was made into matrices from which offset printing took place.
In order to create an electronic form, it was necessary to scan the printed pages of the book into a computer, convert it using optical character recognition ( Recognita program) into alphanumeric form, correct conversion errors, process with a suitable text editor and convert to "html" format. Images had to be captured separately, processed by a graphic editor and implanted in the text. There were big problems with the formulas that fell apart during the conversion. Some formulas have so far been copied from the printed version, it will be further modified. The whole thing was very laborious and demanding!
A number of new findings and concepts were created only after the writing of the manuscript of the book "Gravity, Black Holes and the Physics of Spacetime" (or did not reach the author in time or were not given due importance), so it was not included in the book edition. At the ends of the relevant chapters, or elsewhere in the text, these findings will be gradually supplemented.
A number of errors occurred during the transfer,
Thank you for understanding. Ullmann V.
