Na, You're wrong Potter, the measure of a scientific model
is in the data agreeing with the models predictions. For
example, there predictions of Special and general relativity
have never been contradicted, but confirmed, by observations.

Newton's gravitational theory didn't explain what gravitation
is but does provide reasonable accuracy for calculations.

GTR provides a more complete understanding of gravitation
and is more accurate than Newton... orbital precession,
gravitational lensing, etc. and yes, GTR predicts accurately
the corrections necessary for Global Navigation Satellite
Systems (GNSS).

You've got to admit, Potter, that GPS have proved to be quite
the utility for the world... generating tens of billions of
dollars of economic and utilitarian benefit to the peoples
of this world. Both the quantum mechanics and general relativity
have made that possible. :-)

GTR is an essential tool in investigations of compact
astronomical objects... binary pulsars, supernovae, quasars,
supermassive black holes, galactic evolution and galactic
cluster evolution... Dark Matter distribution and cosmology.
And so on!

Sammy makes a good point!

"GTR is an essential tool"
if you want to model things beyond man's capacity
to ever experience in time and space such as
"binary pulsars, supernovae, quasars,
supermassive black holes, galactic evolution and galactic
cluster evolution... Dark Matter distribution and cosmology.
And so on!" ( Time travel, warping through space, worm holes,
the beginning and end of the universe,
the mind of God, etc.)

Of course, Sammy makes a bad point
when he parrots the lie
that General relativity was and is
essential to the GPS System.

Shame on you Sammy!!!
