General relativity also predicts that time comes to a stop inside black holes, regions of space-time that are so warped that light cannot escape them. But both the beginning and the end of time are places where the equations of general relativity fall apart. Thus the theory cannot predict what should emerge from the Big Bang. Some see this as an indication of God's freedom to start the universe off any way God wanted. Others (myself included) feel that the beginning of the universe should be governed by the same laws that hold at all other times...
...world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological--technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century...

...doing, Einstein hoped also to resolve the conflict between two competing visions of the universe: the smooth continuum of space-time, where stars and planets reign, as described by his general theory of relativity, and the unseemly jitteriness of the submicroscopic quantum world, where particles hold sway...
Einstein worked hard on the problem, but success eluded him. That was no surprise to his contemporaries, who saw his quest as a quixotic indulgence. They were sure that the greatest of all their colleagues was simply wasting his time, relying on a conceptual approach that was precisely backward. In contrast to just about all other physicists, Einstein was convinced that in the conflict between quantum mechanics and general relativity, it was the former that constituted the crux of the problem. "I must seem like an ostrich who forever buries its head in the relativistic sand in order...
