in those ten years, we will have ample time to erect our defenses and seek a way to destroy the Mass—if such a miracle is possible."
He paused as if searching for the right words. "Vignot," he continued. "Would you like to know today—now, just how fatal this coming catastrophe will be?"
"I don't quite understand."
"What I mean is this. Through the remarkable emanations of my Time Projector Machine, I can—"
"Don't do it." Karl Danzig was speaking for the first time. "You'd both be fools. There's nothing to be gained by submitting to such an experiment. You'd both be destroyed in the Thoridium Rays. I'm against the experiment utterly and completely."
"Quiet, Karl," advised Carruthers. "This is between Vignot and me."
"Ah!" sighed Vignot. "A difference of opinion. I never knew you two ever to disagree before. The prospect intrigues me. And since I don't expect, and don't want to live forever, I have little fear of death. Only I don't want to die by slow starvation. I want my meals regular. I want—Ummm. Go ahead, Aaron. And please don't interrupt him, Karl. I'll weigh my chances of survival after hearing a few facts, then I'll make my decision."
"My plan," said Carruthers, "is to project our bodies into the year of 2017—"
"Impossible!" Vignot scoffed.
"Suicidal," added Danzig. "Let's abandon the whole business."
Carruthers eased his lanky body from the chair. He didn't smile, but there was a forceful, inner gleam in his eyes that lighted his whole face.
"There is no other way out for me," he told them, "but to go ahead with my plan. And once I have closed and locked the door to the Time Projector laboratory, I don't expect either of you men to violate my aloneness in that room. Should I come out alive within the next twenty-four hours, I will have the answer to the earth's salvation in my head. Should I fail to return and unlock the door—the task of informing the world of its ultimate end lies with you both." He smiled then. "I guess that's all." With these words he left them and went swiftly down the corridor.
But Aaron Carruthers was not alone when he reached the door to the Projector laboratory. Vignot and Danzig were close behind.
"So!" boomed Vignot. "You want to get rid of me now I'm here and have checked on your arithmetic. You want to make your experiment alone and leave me and Karl behind. Nonsense. We're in this crazy experiment as much as you are. Your dangers will be our dangers."
"Vignot's right," agreed Danzig. "I won't say another word, Aaron. Let's get started."
"I'm grateful to you both," sighed Carruthers, opening the door. "Come in, please. The room is more or less upset, but the apparatus is in perfect working order."
They entered.
"Hmmmm!" grunted the chemist. "What is this machine—an atom smasher?"
Carruthers nodded. "A variation of the main principle, but it goes much farther in its delving into the core of life. This ponderous machine, though much smaller than those giants in use at the government's research laboratories, has successfully bombarded that rare clement of Thoridium, atomic weight 319, "with heavy neutrons thereby stepping its weight up to 320. And since the even-numbered atoms are explosive, the Thoridium split into two parts creating the greatest energy ever produced by man."
He held up his hand as Vignot attempted to break in. "Wait a minute. Let me continue. This energy explosive and
