I do not subscribe to all of his ideas, nor Arp's, but I wholeheartedly encourage the epistemology that is sorely lacking in today's physics. We had to wait a LONG time before Einstein's model of gravitation overtook Newton's (and still NASA can do a pretty nice job using Newtonian gravitation). http://www.cosmology.info/2005conference/wps/burbidge.pdf Note: Inertia is not just a hard-to-describe physical property associated with matter, it also a really powerful property infesting academia. How many decades or centuries of scientific progress have we stifled by establishing educational standards that demand the acceptance of "known truths" in science education before the student can be allowed to discover advanced knowledge, while epistemology is disparaged? Can you say "tunnel vision"?
