**Cognitive bias in physics with respect to Einstein's relativity, demonstrated by the famous experiment of Pound and Rebka (1960), which in reality refutes Einstein's general relativity.**

Einstein’s general relativity postulates that at each positon within a gravitational field we must measure the same frequency f0, but seen from the distance the frequency at the position of another gravitational potential is different from f0. As gravity decreases with the increase of the distance from Earth, in the Pound-Rebka experiment at the top of the tower the frequency of electromagnetic radiation must be higher than at the bottom. If electromagnetic radiation was able to have the same frequency f0 at the top of the tower as at the bottom of the tower, an observer at the top of the tower would have to be able to increase gravity to the same level that gravity has at the bottom. But the decrease of gravity with increase of the altitude cannot be reversed. It is demonstrated that that the relativistic interpretation of the Pound-Rekba experiment showing a doubling of the gravitational frequency shift for "two-way" observations violates the principle of energy conservation, whereas the classical interpretation of the experiment identifies the doubling of the gravitational frequency shift as a pure mathematical effect that has no physical reality, which always occurs when we subtract relative differences with opposite algebraic signs from each other. It is shown that Einstein’s general relativity only seemingly corresponds with reality, thus gravitational frequency (time) shifts must be interpreted according to classical considerations.

### The theory of special and general theory causes a “schizophrenic” dilemma in physics. It undeniably provides mathematically correct values, but it is undeniably epistemologically wrong in many respects. The theory of gravity "Newtonian quantum gravity" (NQG) is an ingeniously simple theory, because it precisely predicts so-called "general relativistic phenomena," as, for example, that observed at the binary pulsar PSR B1913 + 16, by just applying Kepler's second law on quantized gravitational fields.

### It is an irony of fate that the unsuspecting relativistic physicists still have to effort with the tensor calculations of an imaginary four-dimensional space-time. Advanced NQG is also able to derive the gravitational constant G and explains why G must fluctuate. It is not the ﬁrst time that a lack of knowledge of the underlying physical phenomena has to be compensated by complicated mathematics.

### Einstein’s theory of general relativity indirectly already includes additional quantum physical effects of gravitation. This is the reason why it cannot be possible to unite Einstein’s theory of general relativity with quantum physics, unless one uses “mathematical tricks” that make the additional quantum physical effects disappear again in the end.

### Although Einstein's relativity delivers correct numerical results, it is founded on an illogical fundament.

In the experiments concerning time-dilation effects physicists compare always only two atomic clocks, one that is stationary and one that moves or is within another position with respect to the gravitational potential. Using only two clocks, respectively two physical states, the contradictions of relativistic physics are hidden. If more than two clocks are examined in an experiment, there result a lot of contradictions. When one thinks the relativistic explanations of gravitational time dilatation and of the curvature of light rays by masses through to the end, they lead to absurd and contradictory logical conclusions.
