http://www.hawking.org.uk/lectures/dice.html Stephen Hawking: "Both Mitchell and Laplace thought of light as consisting of particles, rather like cannon balls, that could be slowed down by gravity, and made to fall back on the star. But a famous experiment, carried out by two Americans, Michelson and Morley in 1887, showed that light always travelled at a speed of one hundred and eighty six thousand miles a second, no matter where it came from. How then could gravity slow down light, and make it fall back." http://admin.wadsworth.com/resource_uploads/static_resources/0534493394/4891/Ch01-Essay.pdf Clifford Will: "The first glimmerings of the black hole idea date to the 18th century, in the writings of a British amateur astronomer, the Reverend John Michell. Reasoning on the basis of the corpuscular theory that light would be attracted by gravity, he noted that the speed of light emitted from the surface of a massive body would be reduced by the time the light was very far from the source. (Michell of course did not know special relativity.)" So Einsteinians Stephen Hawking and Clifford Will think John Michell was wrong because he did not know the Michelson-Morley experiment and special relativity. However Einsteinians John Norton and Jean Eisenstaedt seem to think that Einsteinians Stephen Hawking and Clifford Will are extremely silly whereas John Michell was right: http://philsci-archive.pitt.edu/archive/00001743/02/Norton.pdf John Norton: "Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity......THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." http://ustl1.univ-lille1.fr/culture/publication/lna/detail/lna40/pgs/4_5.pdf Jean Eisenstaedt: "Il n'y a alors aucune raison theorique a ce que la vitesse de la lumiere ne depende pas de la vitesse de sa source ainsi que de celle de l'observateur terrestre ; plus clairement encore, il n'y a pas de raison, dans le cadre de la logique des Principia de Newton, pour que la lumiere se comporte autrement - quant a sa trajectoire - qu'une particule materielle. Il n'y a pas non plus de raison pour que la lumiere ne soit pas sensible a la gravitation. Bref, pourquoi ne pas appliquer a la lumiere toute la theorie newtonienne ? C'est en fait ce que font plusieurs astronomes, opticiens, philosophes de la nature a la fin du XVIIIeme siecle. Les resultats sont etonnants... et aujourd'hui nouveaux." Translation from French: "Therefore there is no theoretical reason why the speed of light should not depend on the speed of the source and the speed of the terrestrial observer as well; even more clearly, there is no reason, in the framework of the logic of Newton's Principia, why light should behave, as far as its trajectory is concerned, differently from a material particle. Neither is there any reason why light should not be sensible to gravitation. Briefly, why don't we apply the whole Newtonian theory to light? In fact, that is what many astronomers, opticians, philosophers of nature did by the end of 18th century. The results are surprising....and new nowadays." Pentcho Valev pvalev@yahoo.com
