Look up the definition of the word "torsion". That's what you get when you
tighten a bolt under the hood of your car, but I don't see how it applies to solar system orbital mechanics.
You can think of a gravity well, kind of like a stretched flat sheet of rubber with a steel ball in the middle. Try to roll another smaller ball
around and it does tend to circle around and fall toward the big ball.
But this analogy, similar to your towel analogy, has limitations and only models the way the real world works to a certain extent. In the real world,
if you insert the small ball's orbit fast enough, then its own speed will be enough to offset its tendency to fall in to the gravity well. In the
real solar system, unless a planet slows down for some reason, it will never fall in to the sun, especially since the sun is losing mass.
Also, why do you say "This is the accepted theory among quantum theorists"? This would appear to be another misconception. Quantum theory is little
more than a century old. Yet orbital mechanics is based largely on Newtonian mechanics, which preceded that by centuries. It turns out that Newton's
mechanics only explains perhaps 99.9% of the orbital motions we see. To explain the other 0.1% such as the precession of Mercury required relativity,
not quantum mechanics. In fact there is no theory of quantum gravity...this is a gaping hole in current theory which makes it especially odd you would
claim that quantum physicists have an interpretation of gravity...they wish they had a theory of quantum gravity, but they don't. They are working on
it, but they haven't figured it out yet.
Dark matter is responsible for slowing the pace of this to a crawl, instead of a free fall (like the twin towers)
This is another
misconception. We have never had to use dark matter to explain simple orbital mechanics in our own solar system. The orbits are completely explainable
without dark matter.
Furthermore, where dark matter is postulated, as a means of explaining observations in galaxies other than our own, what it is trying to explain is
why they are rotating FASTER than expected, so dark matter appears to be speeding up the rotation, not slowing it down. This is because it's making
the gravity well bigger, not smaller.
If you were thinking of dark energy, that probably has no measurable effect on a scale as small as our solar system, so you can erase that thought, or
else research it to confirm what I said is true. We've only ever observed dark energy effects on much larger cosmic scales.
