Einstein explained that gravity is not an attractive force as Newton claimed; it is a curvature of space. The sun does not exert a gravitational pull on the earth. The earth travels in a curved orbit around the sun, because it is following the curvature of space produced by the sun's gravity. The book explains the principles of Einstein's General theory of Relativity in a simple yet detailed and scientifically accurate manner. This provides the means of exploring the mysteries of cosmology. The theoretical foundation for General Relativity is profound, but Einstein was unable to derive rigorous equations to specify his theory. Shortly after Einstein's death, Yilmaz solved this mathematical problem, and thereby refined the Einstein theory.The Yilmaz refinement of the Einstein theory shows that the curvature of space due to gravity makes the universe expand. The curvature of space seems to be an attractive force within our solar system, yet it seems to act like a repulsive force over cosmological distances. The Yilmaz theory predicts a Steady-State universe that has always existed. Our universe had no beginning, and it will have no end. Big Bang cosmologists have been living off the flawed Einstein equations that specifies General Relativity, deriving physically impossible concepts like Black Holes and Dark Energy. They shun the Yilmaz theory, because it would make their sophisticated mathematics obsolete. Einstein strongly opposed singularity predictions of his theory. Yet cosmologists insist that our whole universe, with its billions and billions of galaxies, each containing billions and billions of stars, was originally squeezed into a microscopically small singularity, which exploded with a Big Bang 13.8 billion years ago, a period that is only 3 times the age of our earth (4.6 billion years).
