In 'Relativity' Einstein wrote - "A curvature of rays of light can only take place when the velocity of propagation of light varies with position." Whilst the 'Crown' (English translation) publication uses the word 'velocity' ilo 'speed' there is no distinction in the German language between those two words however assuming that Einstein was fully aware of the fact that the velocity (i.e. the direction of travel aspect) of a beam of light can very easily be made to change (vary) using a mirror I am of the opinion that he was referring to the 'speed' aspect of light. According to 'Oxford' - propagation means the transmission of light IN A PARTICULAR (SPECIFIC) DIRECTION. Einstein continues - "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 phenomenon (e.g. of light." The concept of the constancy of light speed is one of the gravitational-field-location-invalidated results of special theory to which Einstein referred.
