Kangaroo talks again, Bill?

Newtonian physisics is not wrong but it only describes the condition where
gravity is weak and the observed speed of any object under gravitational
influence is small compared to the observer's observed speed of light in
vacuum. Einsteinian physics (General Relativity) is not quiet correct
because it does not actually predict the observed Mercury's orbital anomaly.
All textbooks and papers have claimed it has but given weak, confusing, and
bogus calculations. It is fraudulent in science. It took Einstein a few
hours to doctor his calculations to what he had already known the answer to
be before the complete set of field equations and even before the most
important element that is the Schwarzschild metric. Of course, after the
solution solved by Schwarzschild, Einstein was able to "formally" derive
Mercury's orbital anomaly without changing his answer but only the
complicated derivation part. This only makes Einstein one of a dozen
creative calculations to arrive at Mercury's orbital anomaly.

Newtonian physically fails at explaining exactly why objects with mass would
even physically atracts each other. Similarly, General Relativity also
fails to explain why objects with mass and thus energy (both observed
parameters) would physically cause a curvature in surounding spacetime.
Thus, GR cannot be regarded as a next-generation theory to Newtonian
physics. If Einstein can adapt his calculations towards what the answer is,
one can also modify Newtonian physics to match the observed.

Not just in relativity, no object physically can be observed to travel
beyond the observer's own observed speed of light in vacuum. This is
already implied in the Lorentz Transforms.

Better brush up on your quantum mechanics.
