Fate of Space and Time: Black holes to Big Crunch

This is one of the early books written for those who prefer words to equations to understand cosmology of black holes. The author attempts to answer basic questions such as; was there a beginning of time? Is there an end to the universe? What are similarities of black holes, singularity, and Big Crunch? Is the universe infinite? Or does it have boundaries? What are the effects of the critical value of the universe's density on its rate of expansion? What is the role of God in the creation of the universe and how it can be evaluated by the anthropic principle? Did God create laws of quantum mechanics and theory of relativity and let it evolve itself without leaving an option for him to intervene? How did he choose an initial state or configuration of the universe? What were the boundary conditions at the beginning of time? The author reviews the literature that includes Newton's laws of gravitational force, Einstein's theory of relativity, and quantum mechanics. Problems arise when one combines these theories to understand the four natural forces; the electromagnetic force; the strong and weak nuclear forces; and the gravitational force by one unified field theory (Quantum theory of gravity, and Superstring Theory). This theory must unify the forces of the cosmos and forces of microcosm so that it can explain the grand plan of God in the creation of heaven and earth. The author describes quite a few interesting anecdotes in academic research: The first experimental evidence in support of Einstein's theory of relativity contained errors that were as great as the effect they were trying to measure. In 1920s it was supposed that there were only three men who understood theory of relativity and now thousands of graduate students and many millions are familiar with this theory: Many readers should be encouraged at this. When the author presented his theory that black hole radiates like a hot body, many repudiated his assertion and later accepted it. Max Born, a Nobel Laureate in 1928 told a group that physics research will end in six months, when Dirac published equations for an electron, in the anticipation that the whole of physics problems are solved. This should remind all of us how far the science and mankind has progressed despite this prediction. Newton, one of the greatest scientists of this planet also had a streak of meanness in him. Einstein's honesty as a scientist could be found when he admitted that his universal constant to account for a static universe is a mistake, but he was also less willing to accept quantum mechanics; this is known by his well known comment that "God does not play dice." Hawking having a bet with Kip Thorne over the existence of black holes in Cygnus X-1 for Penthouse magazine to Private Eye magazine shows the fun side of academic rivalry. This is one of the very few books I have read that discusses God's role at the level of quantum mechanics. The reader should feel lucky to have such a book for his/her personal library.
