THE ESSENCE OF GENERAL RELATIVITY

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."

That is, just like the speed of any material object, the speed of light increases as light is falling in a gravitational field and decreases if the light is travelling away from the gravitational field. The relevant equation given by Newton's emission theory of light is:

c' = c(1±gh/c^2)

and the frequency shift measured by Pound and Rebka unequivocally confirmed the emission theory's prediction:

f' = f(1±gh/c^2)

An important implication is that the gravitational redshift of the light coming to the Earth from distant astronomical objects is due to the simple fact that the speed of that light (relative to the Earth) is decreased.

Clever Einsteinians know that, according to general relativity, the speed of light varies twice as fast as the speed of ordinary matter in a gravitational field: c'=c(1±2gh/c^2). This variation is, obviously, incompatible with the frequency shift measured by Pound and Rebka. Silly Einsteinians know nothing and teach that the speed of light gloriously remains constant in a gravitational field (c'=c), Divine Einstein, yes we all believe in relativity, relativity, relativity.

Both clever and silly Einsteinians regularly set to work to exercise themselves in crimestop. They present themselves with propositions - "the Pound-Rebka experiment gloriously confirmed Divine Albert's Divine Theory", "the light coming to the Earth from distant astronomical objects always has the same constant speed c relative to the Earth" - and train themselves in not seeing or not understanding the arguments that contradict the propositions:

"He set to work to exercise himself in crimestop. He presented himself with propositions - "the Party says the earth is flat", "the party says that ice is heavier than water" - and trained himself in not seeing or not understanding the arguments that contradicted them. It was not easy. It needed great powers of reasoning and improvisation. The arithmetical problems raised, for instance, by such a statement as "two and two make five" were beyond his intellectual grasp. It needed also a sort of athleticism of mind, an ability at one moment to make the most delicate use of logic and at the next to be unconscious of the crudest logical errors. Stupidity was as necessary as intelligence, and as difficult to attain."
