The unification of the fundamental forces of nature is an active field of research. Scientists are clearly guided by a cosmological motivation. The unified field force would be the single force at the beginning of the universe and would evolve into the four fundamental forces as the temperature of the early universe decreased. Until October 2013, no successful theory had been formulated and the unified force had remained a hypothetical force. Since then, an alternative unified field theory is available. The new theory provides a realistic cosmological model. It takes into account, for example, the existence of quasars and supernovae. It also provides new insights into various fields of science, including special relativity, general relativity, quantum mechanics, and elementary particle physics. The new theory does not however meet the cosmological motivation of most of scientists. This series of two books gives the last stroke of the brush at the theory of everything and should be especially useful to professionals and students in basic sciences, or anyone else who is interested in this long-searched for field theory, which settles once and for all the famous Bohr-Einstein debates ascunde descrierea
