Default A Revised Planck Scale?

Yes, but note that Einstein's theory of general relativity does not
disprove Newtonian gravity. It does enable us to describe the domain of
applicability of Newtonian gravity, which could not be done before.
Within that domain of applicability, General relativity can actually be
used to prove Newtonian gravity, which works just as well within its
domain of applicability as it ever did before.



I would like to respond to each of the major themes of your most recent
post, but I would like to take one thing at a time. First and foremost
is your comment above on the status of Newtonian gravitation.

In my view, Einstein's General Relativity relegated the instantaneous,
action-at-a-distance, "force" model characterizing Newtonian
gravitation to the dustbin of scientific history.

Sure, you can still use Newtonian gravitation to simplify calculations
in non-relativistic regimes. But Newtonian gravitation is an
*incorrect* theory of the gravitational interaction. I am at a loss for
how to understand your comments. We don't say the Ptolemaic model of
the Solar System is still valid within its "domain of applicability",
do we?

I am hoping you will clarify your above remarks because understanding
the proper relationship between GR and NG is fundamental.
