Before the Big Bang - way, way out of my depth, but I thought this comment was intriguing: "The paper as published, along with a longer follow up paper, looks to my untrained eye a nearly complete quantum gravitation theory, which is an exciting prospect in itself. However, as with all physical theories, we will await for experimental support before popping the cork." Here's some more on loop quantum gravity, spin networks, the big bang and ekpyrosis.

"A theory that can't predict anything is not a scientific theory," Woit says. That would be string theory, which was going to be the theory of everything, but apparently can't even agree how many dimensions there are. "Those who dabble in alternate-universe speculations might be just modern versions of '16th century theologians (who) speculated that spirits and angels emerge from the extra-dimensional universe,' says Krauss, who is also an outspoken foe of creationist teaching in schools."

Smolin vs. Susskind on the anthropic principle. For those keeping score: Stephen Hawking is for it. Brian Greene is not.
