Default THE GRAVITATIONAL TIME DILATION HOAX

http://www.personal.kent.edu/~fwilli...Relativity.pdf
David Morin: "A light source on top of a tower of height h emits flashes at time intervals Ts. A receiver on the ground receives the flashes at time intervals Tr. What is Tr in terms of Ts?"

If bullets are shot downwards at time intervals Ts, the receiver on the ground will receive them at time intervals Tr=Ts. Yet David Morin's calculations show that, for light, TsTr. Are the calculations based on some implicit false assumption? They must be: Insofar as the speed variation in a gravitational field is concerned, the analogy between bullets and photons is straightforward:

Dr. Cristian Bahrim: "If we accept the principle of equivalence, we must also accept that light falls in a gravitational field with the same acceleration as material bodies."

Robert W. Brehme: "Light falls in a gravitational field just as do material objects."

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..."

"The light is perceived to be falling in a gravitational field just like a mechanical object would. (...) The change in speed of light with change in height is dc/dh=g/c."

Note that, if David Morin is wrong and Tr=Ts, this by no means implies that the frequency of light:

(frequency) = (speed of light)/(wavelength)

does not vary with the gravitational potential. It varies exactly as predicted by Newton's emission theory of light and confirmed by the Pound-Rebka experiment.

Default THE GRAVITATIONAL TIME DILATION HOAX

A javelin graduated in centimeters is thrown downwards from the top of a tower of height h. Initially the centimeter marks pass an observer at the top of the tower with frequency f, speed c (not necessarily the speed of light for javelins) and "wavelength" L (1cm):

f = c/L

What are the frequency f', speed c' and wavelength L' as measured by an observer on the ground? Newton's theory gives a straightforward answer (it is assumed that cc'-c):

f' = f(1+gh/c^2) = (c+v)/L
c' = c(1+gh/c^2) = c+v
L' = L

where v=c'-c is the increase in speed.

Returning to David Morin's question:

http://www.personal.kent.edu/~fwilli...Relativity.pdf
David Morin: "A light source on top of a tower of height h emits flashes at time intervals Ts. A receiver on the ground receives the flashes at time intervals Tr. What is Tr in terms of Ts?"

If we compare the flashes to javelins thrown downwards at time intervals Ts, we see that each flash gets blue shifted because its speed at the receiver is c'=c(1+gh/c^2) and accordingly its frequency is f'=c'/L=f(1+gh/c^2) - a result confirmed by the Pound-Rebka experiment.

On the other hand, the time intervals between the flashes remain unchanged: Tr=Ts. There is no gravitational time dilation.

Nowadays only Bingo the Einsteiniano defends Divine Albert's Divine Theory:

Bingo !!! Bingo the Clown-O!!!

In the past there were very clever Einsteinians who could by no means be called "Bingo the Einsteiniano". So Banesh Hoffmann, although wrongly believing that the frequencies of emission and arrival of the light pulses differ, still knew that there is no gravitational time dilation and that the gravitational redshift is a consequence of the acceleration of light signals in a gravitational field:

http://www.amazon.com/Relativity-Its.../dp/0486406768
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."
