Yes the old text was trying to mislead Einstein zombies into believing that Divine Albert was still alive in 1964! And that was a BLATANT LIE Vigilant Davidson! However the author realized in the end that Einstein zombies are extremely clever, nothing can mislead them etc. and abandoned the idea. The new text clearly demonstrates the author's defeat: http://www.blazelabs.com/f-g-gcont.asp "Irwin Shapiro, it seems, was the first to make use of a previously forgotten facet of general relativity theory -- that the speed of light is reduced when it passes through a gravitational field. He had proposed an observational test to check his prediction: bounce radar beams off the surface of Venus and Mercury, and measure the round trip travel time. When the Earth, Sun, and Venus are most favorably aligned, Shapiro showed that the expected time delay, due to the presence of the Sun, of a radar signal traveling from the Earth to Venus and back, would be about 200 microseconds more than it would if the sun was not present. Later on, using the MIT Haystack radar antenna, the experiment was repeated, matching Shapiro's predicted amount of time delay. The experiments have been repeated many times since, with increasing accuracy. This experiment had for the first time shown that the constants like c and G, assumed constants in Einstein's SR theory suffered local (or regional) in the proximity of massive bodies like the sun. So, faced with this evidence most readers must be wondering why we learn about the importance of the constancy of speed of light. Did Einstein miss this? Sometimes I find out that what's written in our textbooks is just a biased version taken from the original work, so after searching within the original text of the theory of GR by Einstein, I found this quote:"In the second place our result shows that, according to the general theory of relativity, the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity and to which we have already frequently referred, cannot claim any unlimited validity. A curvature of rays of light can only take place when the velocity of propagation of light varies with position. Now we might think that as a consequence of this, the special theory of relativity and with it the whole theory of relativity would be laid in the dust. But in reality this is not the case. We can only conclude that the special theory of relativity cannot claim an unlimited domain of validity ; its results hold only so long as we are able to disregard the influences of gravitational fields on the phenomena (e.g. of light)." - Albert Einstein (1879-1955) - The General Theory of Relativity: Chapter 22 - A Few Inferences from the General Principle of Relativity-. Today we find that since the Special Theory of Relativity unfortunately became part of the so called mainstream science, it is considered a sacrilege to even suggest that the speed of light be anything other than a constant. This is somewhat surprising since even Einstein himself suggested in a paper "On the Influence of Gravitation on the Propagation of Light," Annalen der Physik, 35, 1911, that the speed of light might vary with the gravitational potential. Indeed, the variation of the speed of light in a vacuum or space is explicitly shown in Einstein's calculation for the angle at which light should bend upon the influence of gravity. One can find his calculation in his paper. The result is c'=c(1+V/c^2) where V is the gravitational potential relative to the point where the measurement is taken . 1+V/ c^2 is also known as the gravitational redshift factor." Is now the text OK, Vigilant Davidson? Pentcho Valev pvalev@yahoo.com
