Science does seem to have become more of a business and a religion
It does, but it's the logical evolution, because our ability to verify new hypothesis decreases with time. Before one hundred years people speculated about boundaries of Solar system - now we are discussing about Universe boundaries, while we visited a Moon inbetween.
aether may be so dense that it exerts a powerful gravity that pulls on mass in all directions
This corresponds the "shielding effect" of Fotio-LeSage theory - a pretty ancient one. The concept of dense Aether is quite old
as well, but it was ignored and forgotten nearly completelly.
..Bohmian Mechanics is superior to standard quantum mechanics..
It's hard to say. Every theory, which brings a new paradigm introduces a new postulate in fact. The theories with different postulate set will become incompatible in less or more distant perspective. I've read whole NS article to understand the motivations of such claim.
..Quantum randomness may not be random..
No chaos can be quite random, if such chaos is serving both like object, both like subject of observation. Here are many antagonistic criterions of observability. For example, causal energy spreading in more chaotic environment is weaker, but faster. You will see less, but in larger scope.
In its consequence, chaos concept will bring quantization and determinism into causal observation - no matter, how random it really is. Dense Aether concept isn't so trivial, as it appears at the first glance.
