I don't recall, but it shouldn't be hard to find. PhysicsForum probably has echoes about or whimpers over it. Immediate but very vague intuitive memory is that it's from non-kook forum users stating it as fact and going completely unchallenged (unheard of in nitpick-obsessed communities like those, unless it's almost undoubtedly irrefutable) that I heard about it. Now that I think about it, I remember reading the same assessment from multiple users on multiple independent forums.
