There had been a day when men had maintained one couldn't go faster than light. Also, men had claimed that it would be impossible to force nature to give up the secret of material energy. But here they were, speeding along faster than light, their engines roaring with the power of material energy.
They were plowing a new space road, staking out a new path across the deserts of space, pioneering far beyond the 'last frontier.'
Greg's steps sounded across the room. "We've gone a long way, Russ. Maybe we better begin to slow down a bit."
"Yes," agreed Russ. He leaned forward and grasped the controls. "We'll slow down now," he said.
Sudden silence smote the ship. Their ears, accustomed for days to the throaty roarings of the engines, rang with the torture of no sound.
Long minutes and then new sounds began to be heard ... the soft humming of the single engine that provided power for the interior apparatus and the maintenance of the outer screens.
"Soon as we slow down below the speed of light," said Greg, "we'll throw the televisor on Craven's ship and learn what we can about his apparatus. No use trying it now, for we couldn't use it, because we're in the same space condition it uses in normal operation."
"In fact," laughed Russ, "we can't do much of anything except move. Energies simply can't pass through this space we're in. We're marooned."
Greg sat down in a chair, gazed solemnly at Russ.
"Just what was our top speed?" he demanded.
