...that nothing could be moving faster than light. What happens is that as energy is used to accelerate a particle or a spaceship, the object's mass increases, making it harder to accelerate any more. To accelerate the particle to the speed of light is impossible because it would take an infinite amount of energy. The equivalence of mass and energy is summed up in Einstein's famous equation E=mc2, probably the only physics equation to have recognition on the street...
...return to Zurich in 1912 Einstein had a brainstorm. He realized that the equivalence of gravity and acceleration could work if there was some give-and-take in the geometry of reality. What if space-time--an entity Einstein invented to incorporate the three familiar dimensions of space with a fourth dimension, time--was curved, and not flat, as had been assumed? His idea was that mass and energy would warp space-time in some manner yet to be determined. Objects like apples or planets would try to move in straight lines through space-time, but their paths would appear...
Einstein's general theory of relativity transformed space and time from a passive background in which events take place to active participants in the dynamics of the cosmos. This led to a great problem that is still at the forefront of physics at the end of the 20th century. The universe is full of matter, and matter warps space-time so that bodies fall together. Einstein found that his equations didn't have a solution that described a universe that was unchanging in time. Rather than give up a static and everlasting universe, which he and most other people believed...
...have overcome his deep distrust of quantum mechanics and enthusiastically embraced branes and sparticles and superstrings. And given his almost superhuman ability to transcend conventional thinking and visualize the world in unprecedented ways, he might have been the one to crack the ultimate theory. It may in the end take an Einstein to complete Einstein's unfinished intellectual symphony...
...dimension. Just as one may look off in the distance and see houses, trees, mountain peaks that are landmarks in space, so one may look out in another direction and see births, marriages, deaths that are signposts in time, stretching off dimly into the far future." It does not take much of another stretch to attach godhead to such a vision, though that was hardly Einstein's own feeling...
