the distance light travels in 100 years
Beyond this data begin to fail, but these results already show that the star-density up to a distance of 200 light-years is nearly uniform and such that there are about 2000 stars of a luminosity exceeding 0.01 of that of the Sun in a cubic light-century.
Expressing these large and small measures with reference to the velocity of light, we have an illustration of the scale of the astronomer’s universe—his measures range from the trillionth of a billionth part of one light-second, to more than a thousand light-centuries.
They made a reading on an object-compass focused upon the Earth. Seaton’s face lengthened as seconds passed. When it had come to rest, both men calculated the distance. “What d'you make it, Mart? I'm afraid to tell you my result.” “Forty-six point twenty-seven light-centuries,” replied Crane, calmly.
Edd Cartier tops your staff artists by a few light-centuries.
There were none of his friends near, nor his Mother, nor great-brained Oldster—there was no living thing within innumerable light-centuries.
The percentage of loss among space ships dropped from one ship per thousand light-centuries of travel in overdrive, to less than one ship per hundred and twenty thousand light-centuries, and the causes of the remaining disasters were being surmised with some accuracy.
Midway along the trailing edge was the blister in which Derek lay, senseless over most of his voyage, which stretched a quarter way across the light-centuries of Vermilion Sector.
They stopped every light century until they reached a point where the star was merely a dim point, almost lost in the myriad of stars around it.
We're two light-centuries past the limit of the Hainish Expansion.
And that was what made the nervous serpent shift and slither in his belly as the digital display counted down towards the translation, because after a voyage of over a light-century and a half, it would take an error of only one five-millionth of a percent to give them all an egg’s-eye view of that stone wall.
