I suspect this is the case or that when several such factors coincide, they 
amplify or enable one another, but, so far, not predictably, although both 
Randy and Jerry have been hinting about knowing the (a?) cause and in 
Randy's case, being able to invoke collapse.

He could be right about both.

What would be the point?  It would not prove anything.  We all know that.
