Esse conto é "Efeito Local" , o único trabalho de D. L. Hughes no ISFDB; publicado em Fato Analógico de Ficção Científica , abril de 1968 e aparentemente nunca reimpresso. Trechos:
When studying Galactic science, one finds many systems of thought so odd that it is difficult to understand how sentient beings could have come to create them. None so odd, however, as that which arose on the third planet of the star Sol, where an isolated human culture based an entire system of cosmological science upon the side effects of a derelict space drive. Consider, then, this oddity, as seen through the eyes of Firefoal of Swaylone . . .
[. . . .]
Firefoal paused, and then spoke again. "That experiment is crucial to the development of physics and the space drive. From what the Corps knows of the way physics develops, it is always this experiment which makes the physicist aware of the reality of the spatial fabric. Then they study the properties of that fabric, and are led towards the development of the space drive."
Again he paused, then went on. "But on this planet, with that derelict drive field still operating, the planet will be encapsulated, with the result that the movement of the planet through the spatial fabric will be totally masked. The result is that the interferometer experiment will have a negative result, to that the motion of the planet will appear to have no effect upon the velocity of light. This will produce a paradox which those physicists will have to deal with, and the Corps is interested to find out how they do this. It may be that they have deduced the existence of some artificial interference, or they may have some other solution. Whatever they do, it will be valuable, because the situation is unique."
[. . . .]
Firefoal replied, slowly and musingly. "They did the experiment. They called it the Michelson–Morley experiment after the men who first did it. It did have a negative effect, for the reasons we know of. All this is what one would expect, but after that, their thinking was uniquely odd."
[. . . .]
"Basically, what they did was to assume that conditions on the surface of the planet were completely representative of conditions throughout the universe. This means they did not make the simplest hypotheses which you just mentioned. Instead, they assumed that the velocity of light is constant in all reference systems, for any motion of these systems."
[. . . .]
"Their view of the universe is absurd," said Poleflash. "One cannot create a physical model of the universe, if the speed of light is assumed to be the same in all frames of reference. One cannot even visualize it, or think about it."
"That does not worry them either," replied Firefoal. "They rely heavily on mathematics, as a language of description, and for them, anything which can be described in mathematical terms is satisfactory, whether or not a physical model is possible. [. . .]"
