light-speed n. 2

The skilful hands at the controls were turning adjustments now, and that disc of flame seemed to leap toward him with a hundred light-speeds, growing to a disc as large as a dime in an instant, while the myriad points of the stars seemed to scatter like frightened chickens, fleeing from the growing sun, out of the screen.

Again a tiny ship entered Thett’s far-flung atmosphere, and slowed to less than a light speed, and sent its signal call ahead.

If it goes 34 light speed in the same direction the planet is going, the ship is tearing along at 1 14 light speeds in relation to planet B.

Colonized worlds are like isolated islands in an unimaginably vast ocean, and the ships that ply between them at thirty light-speeds seem merely to creep.

I might well put the…hull to its toughest test yet: smashing it into a neutron star at half lightspeed.

Stith has given us hyperspace where lightspeed is a tad over 22 miles per hour, and levels of reality where characters literally see themselves coming and going.

At three-tenths lightspeed, Pham spent decades in coldsleep getting from star to star.

Once the ship accelerates to its flight velocity of decimal seven two lightspeed, its range is limited only by the amount of fuel it carries to power the force field generators, and indeed the lifetime of the generators themselves.
