But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn't been embraced by everyone--and now, nearly 30 years after it made its initial splash, some of the doubters are becoming more vocal. Skeptical bloggers have become increasingly critical of the theory...
That sort of reasoning drives critics up the wall. It was bad enough, they say, when string theorists treated nonbelievers as though they were a little slow-witted. Now, it seems, at least some superstring advocates are ready to abandon the essential definition of science itself on the basis that...
THE FABRIC OF THE COSMOS By Brian Greene Quick, how many dimensions does space-time have? Answer: 11. Does time really flow forward? Nope. Is teleportation possible? Yep. Greene, a superstring expert who teaches physics and math at Columbia University, uses The Simpsons characters to illustrate the ground rules of...
Superstring theory, which has lately been renamed Mtheory for reasons that interest only theoretical physicists, is so dauntingly complex that the smartest scientists in the world are still trying to nail it down. But among other things, it provides for multiple universes.
For example, he observes, when it was first realized that planets go around the sun, astronomers hoped they might find an underlying principle that would explain why the planets orbit at the precise distances they do. But now we know the orbits are the result of pure chance. The elliptical...
