There are things Newtonian physics can't explain that Quantum physics can. Because Newtonian physicists can't draw a diagram of how the quantum works, they simply deny their existence. Quantum physicists agree with Newton, but on the other hand, they're searching even deeper, because the world and it's miracles are still vastly unknown. There are too many "quirks" associated with the human existence for Newtonians to explain (if someone could get them to believe they exist, i.e., the human energy field, spontaneous healing, ESP, telepathy, worm holes, time space, synchronicities...).
Not one word of what you have posted is true.
There are NO "Newtonians." Newtonian Physics is an approximate theory of nature that is included as part of quantum theory. In the limit as Planck's constant becomes small relative to the size of the problem domain, Newtonian Physics is correct to a very high degree of approximation. But there is NO Physicist now alive who believes that Newtonian mechanics is fundamentally correct.
My guess was that it is a property of dark matter.
