Motivation

This article fails to motivate why this is a problem. Why should one expect θ to be non-zero? Sems perfectly natural to have a zero here, so the declaration that "there's a problem here" is unconvincing as currently worded. linas 00:17, 15 December 2005 (UTC)[reply]

Irrelevant ref?

How on earth is Bars's two time physics related to the strong CP problem? If some latter work made a connection, cite that work, but that paper is irrelevant. I'm removing the ref and putting in the Peccei-Quinn ref. Dewa (talk) 01:08, 3 May 2013 (UTC)[reply]
