Sure. NM predicts the orbits of satellites
and planets quite precisely. It only miss on
the advance of the planets' perihelion.

Any particular reason why you are babbling
meaningless nonsense in stead of responding
to what I wrote?
  Try again?

According to Newton's second law of motion the acceleration
of a body with mass m is a = F/m where F is the force acting
on the body.

Example from the real world:
A commercial aircraft will accelerate at a ≈ 3.5 m/s² before
takeoff. If your mass is m = 80kg, the force the backrest of
the seat is exerting on your back is F = (80⋅3.5)N = 280N = 63 pound.
You are pushed against the backrest, so you can feel the force
pushing your back. An accelerometer in your hand will show that
your horizontal acceleration is 3.5 m/s².

Fact:
If you are accelerating horizontally on the ground, you can
always feel the force that are accelerating you, and the
accelerometer in your hand will show the acceleration you feel.

When you are weightless orbiting the Earth, you can feel
that no force is acting on you, and the accelerometer in your
hand shows that your acceleration is zero.
So how can NM claim that you are accelerating?

Example from the real world:
Sentripetal acceleration of a person in the ISS according to Newton:
Orbital radius r = 6787km, orbital speed v = 7.67 km/s,
centripetal acceleration a = v²/r = 8.67 m/s²
That's almost 1g! A person with mass 80 kg should according to
Newton's second law of motion feel the force F = ma = 693N = 156pound!

But he is weightless and his accelerometer shows zero acceleration!

Can you explain this paradox? Will you blame it on Einstein? 😂

(GR always agree with the accelerometer.)
