...Even Einstein would probably be taken aback, though, by experiments announced in Cambridge, Mass., last week: two teams of scientists have slowed light to a dead stop. The achievements, to be reported in this week's issue of Nature and next week's Physical Review Letters, could one day lead to a new generation of compact, superfast computers that operate by light, not electricity...
...Albert Einstein showed nearly a century ago that light always travels at one speed--670 million m.p.h.--but his Special Theory of Relativity had an often overlooked qualifier: this blistering pace applies only in a vacuum. When it passes through air, say, or glass or water, light goes a bit slower...
Harvard researchers have found what they call the most compelling evidence yet for the existence of black holes and the "event horizons" that surround them, confirming with actual observations a result predicted 86 years ago by Einstein's theory of general relativity...
...Einstein's 1915 general relativity theory has predicted the existence of black holes and event horizons. But until recently, telescopes were too imprecise to tell the difference between dim neutron stars and even dimmer black holes...
...demonstrating the presence of event horizons, the Harvard researchers say that they have supplied more conclusive evidence that black holes resemble the predictions of Einstein's theory...
