Albert Einstein

Albert Einstein played a huge role in the advancement of the sciences of physics and mathematics. Einstein developed many theories but his theory of relativity and his general theory of relativity are the best known to the general public. He included the concept of curved space in his general theory of relativity. The theory made the assumption that the "physical space becomes curved in the neighborhood of large masses." Einstein had come to the conclusion that "the phenomenon of gravity is merely the effect of the curvature of the four-dimensional space-time world." A big problem that faced Einstein in reconciling his general theory of relativity was the dilemma of whether the universe was finite and infinite.

Contraction is a physical phenomenon that Einstein dealt with in developing some of his theories. Some contraction of a material body moving through a resisting medium is an expected result. A...
