In a century that will be remembered foremost for its science and technology--in particular for our ability to understand and then harness the forces of the atom and the universe--one person stands out as both the greatest mind and paramount icon of our age: the kindly, absentminded professor...
Einstein's conclusions became known as the special theory of relativity. No matter how fast one is moving toward or away from a source of light, the speed of that light beam will appear the same, a constant 186,000 miles per second. But space and time will appear relative...
The most careful and accurate of these experiments was carried out by Albert Michelson and Edward Morley at the Case Institute in Cleveland, Ohio, in 1887. They compared the speed of light in two beams at right angles to each other. As the earth rotates on its axis and orbits...
We know now, however, that it is Einstein's theory that ultimately fails. On extremely fine scales, space-time, and thus reality itself, becomes grainy and discontinuous, like a badly overmagnified newspaper photograph. The equations of general relativity simply can't handle such a situation, where the laws of cause...
