Sean Carroll now says no multiverse:-"His starting point was the idea that quantum fluctuations are dependent on interactions with an external system or particle, known as an "observer" ... a familiar concept in quantum mechanics. When he applied this thinking to our view of inflation, it changed everything. The inflaton must have preceded all the other particles in the very early universe. That means it was the only type of particle that existed, so there would have been nothing "external" for inflatons to interact with, says Carroll. In this case, the inflaton would not have undergone quantum fluctuations.-"This "quiet" state lasted until the inflatons decayed into different types of ordinary particles, which could then interact with each other. "Then those quantum fluctuations finally come to life," says Carroll ... allowing them to fulfil their crucial role of seeding the cosmic web but removing the need for an infinitely budding multiverse."-He changed his mind.-http://www.newscientist.com/article/mg22229692.600-quantum-twist-could-kill-off-the-multiverse.html?full=true#.U3YKpNIU
