Whilst The Source Field Investigations is indeed a compelling read - and features many stunning revelations, it is one of these books that fundamentally undermines itself. How? Graham Hancock hints at it in his endorsement when he says "There is a tremendous amount of good science here" - the implication being that there's also a lot of not very good science here too, which unfortunately is the case. By referencing this not-very-good-science alongside the good science, Wilcock muddies the water and ends up fundamentally undermining his credibility and his whole evidence dossier on the Source Field theory. Which is a real pity as its a neat and elegant theory!
Alternative theorists / thinkers have to tread a difficult line being proponents of alternative ideas and concepts but with enough supporting facts or indicators to gives their ideas some justification. The challenge they face is that as soon as solid scientific evidence is found to discredit (or support, occasionally) an alternative theory then that idea / concept / phenomenon ceases to become alternative and becomes conventional mainstream (accepted) science-fact or proven innaccuracy.
With a diminishing pool of ideas (and a competitive alternative science marketplace), alternative theorists are forced into new areas, and it seems universally the case that their ideas become more and more radical with less and less supporting evidence. This may sell books to the faithful fan-base of fantacists, but to the rest of us - Alternative Science just looks a little nuts...
Wilcock is well into this zone, and the sheer lack of concrete evidence, peer reviewable / re-creatable science is just painful at times, and you cry out "Why David, Why?! By citing this you've just made yourself look silly and now I have to wonder whether everything else you've just told me is also complete nonsense!" Of course the most incredible scientific "discoveries" are all conventiently seized upon by the covert worldwide intelligence police of the global power elite, and then stowed away never to see the light of day again - leaving us with only tantalising glimpses. Hmm, for this kind of scientific policing to be possible they'd certainly need time-travel capability - but then if they did - why would they leave us any tantalising glimpses at all? You can see how so many Alternative Theorists get their nickers in a twist.
And this is a great pity as alternative views, ideas and interpretations have a really important role to play in keeping institutionalised mainstream science on its toes.
Wilcock has written a fascinating and enjoyable book, but there's just too much nonsense and unverifiable science for it to be taken seriously as a scientific investigation.
