Having now had Roy's theory outlined to me privately i'd just like to say it's very interesting and well worth checking out. It's not what i was expecting let me say that, and dare i even say...very plausible. And if it stands up to deeper questioning, quite remarkable.

Apologies if this sounds like a full on plug for the book, it's just my honest opinion based on what i've been shown so far, so i thought i'd share it. :)
