Good onya, Ernie !
Looking forward to your comments .. This guy, Cahill is definitely a challenge and the conceptual basis of his theories are definitely a huge stretch for amateur scientists !
He's published about 61 papers I can find so far, (eg: on the arXiv server), and he has some interesting ideas. I'm pretty sure his theories lack consistency .. but, then again, all theories have their weaknesses. He doesn't seem to have much support from his peers, although I've found an Italian scientist, (M. Consoli), who has taken up a few of the challenges left behind by Cahill.
More later, perhaps.
Cheers & Rgds
