Thus the two fell silent and awed as they gazed out into the abysmal depths of the interstellar void. The darkness of Earthly night is ameliorated by light-rays scattered by the atmosphere: the stars twinkle and scintillate and their light is diffused, because of the same medium. But here, what a contrast!
For the most part, the mirage of the desert is a baseless illusion, depending on the bending of light-rays by air strata of differing densities.
Sound-waves for example light-rays, electricity these have been freely at our service from the beginning. Electricity might have been used ages ago, had not dull-witted man refused to find anything better for lighting purposes than an oil-lamp or a tallow candle! If, in past periods, he had been told 'there is something else' he would have laughed his informant to scorn.
Instead of picturing to ourselves, as is usually done, light-rays which are shifted away from or towards the perpendicular at the border-plane between two media of different optical properties, we shall rather build up the picture as light itself designs it into space.
Rovol moved more controls and the structure again righted itself, swinging back into perfect alignment with the tube and carrying the faidon upon its extremity, a thousand yards beyond the roof of the laboratory. "We are now ready to start our projection. Be sure your suit and goggles are perfectly tight. We must see what we are doing, so the light-rays must be heterodyned upon our carrier wave.
We must give Vic a hand mustn't we? Naturally, I didn't understand Vic's jargon about frequencies and light-rays, for I thought more about football than physics in college, but two things were clear to me. One was that Vic had plunged into some sort of wild experiment, and the other was that Hope had followed him. The rest didn't matter very much. "Perrin! Mr. Butler and Miss Hope are safe.
The masters who are able to materialize and dematerialize their bodies or any other object, and to move with the velocity of light, and to utilize the creative light-rays in bringing into instant visibility any physical manifestation, have fulfilled the necessary Einsteinian condition: their mass is infinite.
Not only is it waterproof against wet, a fur overcoat against cold, and a water jacket against heat, all in one, but it is also a very important member of the "look-out department," being the principal organ of one of our senses, that of touch. The eyes in the beginning were simply little colored patches of the skin, sunk into the head for the purpose of specializing on the light-rays.
In two or three of the cities the Water City particularly there was a show of rebellion among the people; but our light-rays cowed them instantly, and in no instance did we have to kill or injure any one. Through Miela I made speeches everywhere.
There were many lateral ravines depressed below the upper surface of the main plateau, and though the light-rays from the city, directed horizontally, would sweep their tops, we found we could traverse many of them a considerable distance in safety. But from the bottoms of them we could only fire our rockets without specific aim and our projectors not at all.
