Although it is interesting to imagine traveling at or beyond the speed of light, Einstein points out that it is not possible. Light speed is the speed limit of the universe. Einstein?s equation,S=mc2, or Energy equals mass times the speed of light squared, proves it impossible. As a spaceship?s speed increases, so does its mass. As the mass increases, so does the energy needed to make it accelerate. The mass and energy may go up to astronomical numbers, but it would take an infinite amount of energy and mass to achieve light speed (Feynman 51)."General Relativity deals with reference frames that are accelerating and Phenomena that occur in strong gravitational fields" (Gundersen, 386). Einstein hypothesized that a person in an "at rest" elevator cannot differentiate between that and the same elevator accelerating through space without any outside influence of gravity. Albert suggested that acceleration and gravity are mathematically identical. From this he derived his concept of space-time. According to Einstein, mass bends or warps the space-time continuum (Laing,486). He considered another "thought experiment," in which a pool table is composed of rubber. A weight is placed at the center of this rubber table, and as a result, a sinkhole or a dip is created in the surface of the table. It is now impossible for any of the balls to travel in a straight line. Their trajectories are warped by the bending of the surface. This is precisely what Einstein envisioned happening to planets, the moon, and the rest of the cosmos. This is the reason that Earth orbits the sun and the moon revolves around the sun. "He (Einstein) maintained that gravity, as an invisible force that pulls apples and other things to the ground does not exist," states Chaisson (99).Albert Einstein hypothesized some of the most complex theories of all time, Special and General Relativity. His Genius reshaped the way scientists think and the way we look at th...
