Review of Modern Cosmological Theories

  • A. Karel Velan

Abstract

The generally accepted theory of the birth and evolution of the universe is the classical big bang model. According to this theory, 12–15 billion years ago the universe was born from a cosmic explosion or “big bang” of the “singularity.” The singularity contained the entire mass of the universe in the form of elementary particles of matter and electromagnetic energy at infinite temperature, compressed to infinite density in zero space. The mass at infinite density created infinite gravity and, consequently, a complete curvature of space around it. For all practical purposes, the singularity disappeared from space. Nevertheless, in accordance with this theory the entire universe as we observe it today with all the galaxies, stars and planets, white dwarfs and pulsars, quasars and black holes evolved from this gigantic explosion, followed by expansion and cooling down.
