Lee Smolin is an extremely non-combative dissenter to the modern approach to quantum gravity, but he also has a certain degree of fame as a respectable groundbreaking physicist, and he has written previous books on quantum gravity. So it's no suprise that his feet are being put to the coals when he says that String Theory is in a LOT of trouble.
This is Lee's new book:
The Trouble With Physics: "The Rise of String Theory, The Fall of a Science, and What Comes Next"
The following is the introduction to an interview with Lee, by Adam Rogers of "WIRED Magazine", one of many interviews that are sure to take place now that Lee's new book has finally hit the market:
By Adam Rogers
String theory was supposed to reconcile the subatomic world with the vast reaches of spacetime. Now Lee Smolin wants to unravel it.
The universe has a problem. The math that describes gravity and the structure of spacetime – general relativity – conflicts with the math that describes the interactions of subatomic particles – quantum mechanics. For the past two decades, the dominant approach to unifying the two has been string theory, which basically says that the universe is made of infinitesimally small, vibrating filaments of energy moving through multiple dimensions. It's wacky stuff, but no weirder than a lot of other science. Yet in his new book, The Trouble With Physics, theoretician Lee Smolin argues that string theory is not only weird, it might be wrong. A founding scientist at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Smolin says that string theory is unconvincing – maybe even nonscientific – and that physicists have embraced it at the expense of other promising research. At home in Toronto, Smolin talked about physicist cliques and the true nature of the universe
