As far as I can tell there is no evidence for a hidden science of astronomy, in either astrology — which the article reminds you, has been shown to be empirically false — nor in the structure of amphitheaters. The latter is well understood on the basis of standard architectonics and physics.
Science is not a religious belief, and it is charlatans like Deepak Chopra who misuse quantum mechanics to make claims about spiritual experiences — not physicists.
Nor is science about absolute truths. As demonstrated by the literature on the history and philosophy of science.
