"If the matter here is the same as the matter back home, we'd have a fifty-fifty chance of it being contraterrene. It might even be something that was neither terrene or contraterrene for all we know."
"Interesting possibility. You mean something that is neutrally charged so far as we're concerned, but which in this universe consists of oppositely charged items?"
Billy nodded. "We'll find out."
"It has atmosphere, and the test shell didn't result in a contraterrene indication," called the pilot of the project.
"An atmosphere of what?"
Rhodes grinned. "God-knows-what," he said. "If Stellor can't make head nor tail out of the spectrograph, the chances are that the atomic stuff here might not jibe with ours at all."
"There is really no reason for our planeting at all," said Billy. "But I'm just curious, that's all."
"We'll be there soon."
The project approached the planet, and was forced to drive all the way. By the time that they had matched the angular velocity of the planet's rotation, the project was inverted with respect to the surface—though to the men it seemed as if they were driving up to a ground-surface. It gave them an eerie feeling.
