Default Why Einstein's General Relativity Is Nonsense

Einstein fabricated his absurd gravitational time dilation in 1911:

Einstein 1911: "Nothing compels us to assume that the clocks U in different gravitation potentials must be regarded as going at the same rate" http://www.relativitycalculator.com/...ht_English.pdf

Then, in 1915, he had to reconcile the 1911 absurdity with the gravitational redshift predicted by Newton's theory. The reconciliation is only possible if the speed of falling light idiotically DECREASES - the acceleration of photons must be NEGATIVE, (-2g) near Earth's surface. This decrease of the light's speed was nonsense but at the same time it was a fudge factor allowing Einstein to preserve his cherished gravitational time dilation in the final version of general relativity:

"Contrary to intuition, the speed of light (properly defined) decreases as the black hole is approached. [...] If the photon, the 'particle' of light, is thought of as behaving like a massive object, it would indeed be accelerated to higher speeds as it falls toward a black hole. However, the photon has no mass and so behaves in a manner that is not intuitively obvious." http://www.physlink.com/Education/AskExperts/ae13.cfm

"...you will find in section 3 of that paper Einstein's derivation of the variable speed of light in a gravitational potential, eqn (3). The result is: c'=c0(1+φ/c^2) where φ is the gravitational potential relative to the point where the speed of light c0 is measured. Simply put: Light appears to travel slower in stronger gravitational fields (near bigger mass).. [...] You can find a more sophisticated derivation later by Einstein (1955) from the full theory of general relativity in the weak field approximation. [...] Namely the 1955 approximation shows a variation in km/sec twice as much as first predicted in 1911." http://www.speed-light.info/speed_of_light_variable.htm

"Thus, as φ becomes increasingly negative (i.e., as the magnitude of the potential increases), the radial "speed of light" c_r defined in terms of the Schwarzschild parameters t and r is reduced to less than the nominal value of c." https://www.mathpages.com/rr/s6-01/6-01.htm

Actually the speed of falling light INCREASES (near Earth's surface the acceleration is g), as predicted by Newton's theory:

University of Illinois at Urbana-Champaign: "Consider a falling object. ITS SPEED INCREASES AS IT IS FALLING. Hence, if we were to associate a frequency with that object the frequency should increase accordingly as it falls to earth. Because of the equivalence between gravitational and inertial mass, WE SHOULD OBSERVE THE SAME EFFECT FOR LIGHT. So lets shine a light beam from the top of a very tall building. If we can measure the frequency shift as the light beam descends the building, we should be able to discern how gravity affects a falling light beam. This was done by Pound and Rebka in 1960. They shone a light from the top of the Jefferson tower at Harvard and measured the frequency shift. The frequency shift was tiny but in agreement with the theoretical prediction. Consider a light beam that is travelling away from a gravitational field. Its frequency should shift to lower values. This is known as the gravitational red shift of light." https://courses.physics.illinois.edu...re13/L13r.html

"To see why a deflection of light would be expected, consider Figure 2-17, which shows a beam of light entering an accelerating compartment. Successive positions of the compartment are shown at equal time intervals. Because the compartment is accelerating, the distance it moves in each time interval increases with time. The path of the beam of light, as observed from inside the compartment, is therefore a parabola. But according to the equivalence principle, there is no way to distinguish between an accelerating compartment and one with uniform velocity in a uniform gravitational field. We conclude, therefore, that A BEAM OF LIGHT WILL ACCELERATE IN A GRAVITATIONAL FIELD AS DO OBJECTS WITH REST MASS. For example, near the surface of Earth light will fall with acceleration 9.8 m/s^2." http://web.pdx.edu/~pmoeck/books/Tipler_Llewellyn.pdf

The Pound-Rebka experiment unequivocally confirmed Newton's prediction:

Albert Einstein Institute: "One of the three classical tests for general relativity is the gravitational redshift of light or other forms of electromagnetic radiation. However, in contrast to the other two tests - the gravitational deflection of light and the relativistic perihelion shift -, you do not need general relativity to derive the correct prediction for the gravitational redshift. A combination of Newtonian gravity, a particle theory of light, and the weak equivalence principle (gravitating mass equals inertial mass) suffices. [...] The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..." http://www.einstein-online.info/spot...te_dwarfs.html

R. V. Pound and J. L. Snider, Effect of Gravity on Gamma Radiation: "It is not our purpose here to enter into the many-sided discussion of the relationship between the effect under study and general relativity or energy conservation. It is to be noted that no strictly relativistic concepts are involved and the description of the effect as an "apparent weight" of photons is suggestive. The velocity difference predicted is identical to that which a material object would acquire in free fall for a time equal to the time of flight." http://virgo.lal.in2p3.fr/NPAC/relat...iers/pound.pdf

Default Why Einstein's General Relativity Is Nonsense

Hanoch Gutfreund: "The general theory of relativity predicts that time progresses slower in a stronger gravitational field than in a weaker one." http://www.huffingtonpost.com/hanoch..._7314788..html

Actually the prediction is much more idiotic than that: General relativity predicts that gravitational time dilation occurs even in a HOMOGENEOUS gravitational field:

"the homogeneous gravitational field is the gravitational field which, in every point, has the same gradient of the potential. Such a field is produced by an infinite material plane with the constant surface density of mass." http://cds.cern.ch/record/538836/files/0202058.pdf

This means that two clocks at different heights are in EXACTLY THE SAME immediate environment (experience EXACTLY THE SAME gravitational field) and yet one of them ticks faster than the other. That is, according to general relativity, the effect (gravitational time dilation) has no physical cause.

"Effect without cause" is not a problem in Einstein's schizophrenic world (Einsteinians worship even greater idiocies) but clever Einsteinians feel uncomfortable from time to time and admit that there is no gravitational time dilation:

Banesh Hoffmann: "In an accelerated sky laboratory, and therefore also in the corresponding earth laboratory, the frequence of arrival of light pulses is lower than the ticking rate of the upper clocks even though all the clocks go at the same rate. [...] As a result the experimenter at the ceiling of the sky laboratory will see with his own eyes that the floor clock is going at a slower rate than the ceiling clock - even though, as I have stressed, both are going at the same rate. [...] The gravitational red shift does not arise from changes in the intrinsic rates of clocks. It arises from what befalls light signals as they traverse space and time in the presence of gravitation." http://www.amazon.com/Relativity-Its.../dp/0486406768
