Tommy sat in the pilot's seat and urged the ship slowly forward, using rocket blast after rocket blast to keep it on its course.

"You have to fight to stand still here," he gritted between his teeth. "A man can't tell just where he is. There doesn't seem to be any direction, nothing to orient oneself.”

"Of course not," rumbled Kingsley. "We're in a sort of place no other man has ever been. We're right out in the area where space and time are breaking down, where lines of force are all distorted, where everything is jumbled and broken up.”

Gary stared out through the vision plate. There was nothing to see, nothing but a deep blue void that queerly seemed alive with a deep intensity of life.

He turned from the panel and asked the Engineer:

"Any signs of energy yet?”

"Faint signs," said the Engineer, bending lower to peer at the dial set in a detector instrument. "Very faint signs. The other universe is almost upon us now and the lines of force are just beginning to make themselves felt.”

"How much longer will it take?" asked Kingsley.

"I cannot tell," said the Engineer. "We know very little about the laws out here. It may be a very short while or it may be some time as yet.”
