Blaine laughed cheerfully. "You haven't much to say about this."

Les spat in the other's direction. "Don't let me get within grabbing

distance of that gun," he told Blaine. Disdainfully, he turned his back

and faced Tansie.

"Is it true?"

She looked at Blaine.

Blaine said, in a cold voice, "Tell him the truth, Tansie--or I'll kill

_him_."

Ackerman turned again. "Truth?" he sneered. "Truth at the point of a

gun? 'Truth' in this case is forcing Tansie to make a statement that

you approve. Truth! Bah!"

Tansie looked at Ackerman, then at Blaine; this was an event she

had not counted on. Tansie had believed that the history she

knew--unwritten but known--was truth, despite its happening in the

future respective to 'Real Time.' She had been wondering about

predestination and the resulting futility of all effort; this seemed

to prove to her that this nebulous life was still subject to change at

the whim of chance. But Ackerman was important, and even though his

definition of truth was correct in this case, he must not be destroyed.

She looked at Blaine and then at Ackerman; the collapse of all her

hopes had stricken her dumb.

Tears were close to the surface. Tears for herself, for her hopes--and

for Les Ackerman. Yet there was a chance. Les must not be destroyed,

even at the expense of her own life; Blaine knew that, which was why he

threatened Ackerman instead of her.

Calvin Blaine lifted the carbine.

Les Ackerman measured his chances and decided against them, for the

moment at least.

With hidden tears stinging her eyes, Tansie Lee held up her left hand.

Ackerman looked down and saw it. Very plain, very formal, as lacking in

surface glitter as Tansie had seemed--Les wondered whether the simple

serenity of the wedding ring was as false a cover for cheap green brass

as--as--

_You damned fool!_ he told himself. _You trebly underlined,

capital-lettered idiot! A soft glance, warm lips, and an

almost-invitation--and you forget yourself!_

The blind, stupid haze cleared from Ackerman's bewildered mind and he

looked into Tansie Lee's face. She had been looking at him, searching

his face carefully. But she had seen his expression, and was turning

away. Ackerman watched her go, coldly. _A fool_, he said to himself,

_is a man who makes the same mistake twice!_

Tansie walked away, her shoulders down, her warmly-rich figure gaunt,

and the line and soul of dejection.

* * * * *

Calvin Blaine coughed and said: "Sorry, Ackerman. This is mostly for

self-defence. I knew she'd work on you very well before I got to

you--and I knew that she'd work well enough to drive you into blind

fury at the first mention of her perfidy."

"I don't understand all of this," said Ackerman. His voice was hard and

his attitude one of complete indifference. "What's going on, anyway?"

"You've heard of two countries, or two men fighting for their lives?"

"Yes."

"Ackerman, you started this. Unwittingly, of course. Bombardment of

Element X--which we call _Temperon_--produced a freak field of force

that caused a division in the universal stream of time. It has never

happened before and it will never happen again according to the

probabilities--no one knows what happened.

"This, Ackerman, produced a twin existance. Two probabilities that stem

from a dual explosion in your laboratory. In one, there was a complete

success to your work; in the other, there was total destruction of your

effort. Not only did you split the world into twin existances through

'time', Ackerman, but you also split it definitely into twin camps of

reasoning. Your work was based upon findings that came from countries

that were enemies not many years before. Figuratively, you stood on the

shoulders of scientific wisdom to prepare your manuscript of facts on

the element temperon.

"Your work was an indictment of any policy that would hamstring the

free interchange of ideas, concepts, work, and success. It was living

proof that all men contribute to the advancement of civilization

whether they be good, not so good, bad, quick, dead, friend or one-time

enemy.

"The other existance, however, has your evidence that men were plodding

through the uncharted seas of boundless energy and power--"

"But I was not!" stated Ackerman.

"You know that and your fellows know it. But your scientific fellows

are a minority, and many of them doubt their own figures. They know

only that _something_ blew you and your laboratory off of the face of

the earth, and they all wonder why--even those who claim to _know_

that you were working with nothing dangerous.

"Therefore, Ackerman, because you and your kind were obviously playing

with a field of work that might cause the destruction of the universe,

research is throttled and controlled to within an inch of its life.

There is no leaping from an unfounded theory to cold mathematics to

foregone conclusion like a fast double-play from short to second to

first. To bombard a ten milligram sample of anything never before

bombarded, the scientist must make ten ten-hour bombardments, adding

one milligram each time."

"Well--where do I come in?" asked Ackerman.

"You have the answer to mankind's life in your brain," replied Blaine.

"We need your help."

"That's about what Tansie Lee was telling me." Ackerman's mind

underwent a very brief session of self-denunciation at the thought of

Tansie.

"I'll show you," he said. "My ship is hard by. I'll show you, Ackerman,

the destruction of a solar system by men who know too little about the

stuff with which they work."

Ackerman shrugged uncertainly. "I'm not Solomon, nor even one of his

seventh-assistant helpers," he said thoughtfully. "But it strikes me

that there is as much danger letting everybody play with atomic fire as

there is in throttling all brainwork."

Blaine laughed heartily. "Any kind of fire," he said between shouts of

admiring laughter. "Even firewater! They tried complete prohibition

once and people started to make everything from Allyl Acetate to

xylylene glycol in their cellars! No one yet has thought of legislation

forcing everybody to swizzle a quart a day, and even the flushest of

lushes doesn't offer drinks to kids. No, Ackerman, you're to be proven

correct."

"Why?"

"That's partly why we need your help," said Blaine. "People have been

bootlegging science to a dangerous degree. In the other existance,

people have been taking a free and untrammelled holiday. In the future

to which we're going, you'll see the answer. Men have learned the folly

of fighting one another, Ackerman, but they have also learned the way

across the strait of 'time'. Burning up my world by atomics will not

cause their own world to die."

"Doesn't that give them both a future?"

Blaine clapped Ackerman on the shoulder and smiled sorrowfully. "They

cannot cross materially," he said. "They can blast only with energy.

Yet, even so, there is jealousy, hate, and malice. Remember this,

Lester Ackerman: what man cannot conquer, man destroys!"

* * * * *

Calvin Blaine's ship was about the same as Tansie's. Blaine motioned

Ackerman in and followed, closing the door. From the controls, up

in the pilot's deck, came a musical voice that struck a chord in

Ackerman's mind: "You found him, dad?"

"My daughter," said Blaine unnecessarily. She came to meet them; a

golden blonde with sparklingly mischievous eyes, upturned corners of a

round, rich mouth that was also generous, and a warmly tanned skin.

"This is he, Laurie. Ackerman, my daughter, Laurie Blaine."

"How do you do, Miss Blaine."

"I do fine, usually," she told him with a laugh. "And I start at once;

you are to call me Laurie; I'll eschew formality, too, and call you

Les." She turned to her father. "Are we off in the planned direction?"

"We are. I succeeded in getting to them before any damage was done."

"Soon enough?" asked Laurie with a devilish glint in her eye. Ackerman

squirmed uncomfortably, wishing he could duck the double entendre.

Calvin Blaine recognized the possibility of Ackerman's

discomfort--possibly because Blaine was no more perfect than anyone

else. He would never tell Laurie that he had interrupted a love-scene;

she would never know unless Ackerman blurted it out.

He nodded negligently. "He didn't know who she was," he said.

Laurie smiled at Ackerman. "We know that Les Ackerman is a shy man,"

she said. "It--is becoming. But to tell you the truth, Les, I'd be

worried about a bronze statue if that woman decided to hurl herself at

its head." The way Laurie said 'That woman' was of the same tone that

one uses in describing someone who was violating the 'No Spitting'

ordinance in the subway. "You're still pure and simple?" she asked him

with a laugh.

"I'm simple, anyway."

"Good; I'm not too bright in some things. Dad's tried to tell me about

temperon. I'm baffled; what's temperon?"

* * * * *

Ackerman took a deep breath and was frankly glad to get off of the

tender subject of his affections and onto a more stable discussion of

material physics.

"It's an involved yarn," said Ackerman. "Back in the nineteen-thirties,

a scientist by the name of Enrico Fermi was successful in bombarding

almost every element with neutrons, and succeeded in most cases by

raising the atomic number of most of them. The neutron, you see,

enters the nucleus, making the nuclear mass too great for the nuclear

charge. The nucleus then re-establishes stability over a time by

emitting a beta particle, transforming, in effect, one of the neutrons

to a proton. Now the top of the periodic chart is uranium, and Fermi

wondered what he would get if he tried to raise the top-number."

"That was plutonium?" asked Laurie.

"Neptunium first, then plutonium. After the Second War, science took

up again, investigating for the sake of learning more about their

surroundings. Plutonium was top-number for not too long. Element

ninety-five came next, and ninety-six followed soon. We were working

on element number one hundred and forty-four; that is the one called

temperon."

"There are that many elements above the former top?"

"There are, theoretically, an infinite number of elements. Most of the

top elements are unstable--that is, radioactive. Fissionable elements

occur more and more frequently in the top brackets. No one has ever

seen element one hundred and eight, you know; it fissions automatically

as soon as it is made."

"How do you hurdle it, then?"

"Bombard it with deuterons, which raises the charge one number and the

mass two numbers. It isn't easy, but it works." He looked at Laurie

with curiosity. For an avowed lack of education in atomics, Laurie knew

the proper questions to ask. He wondered whether her interest was as

great or her desire for knowledge as deep as she said--or whether she

were doing her best to put him at ease by leading him into talk about

the subject he liked best.

Then, surprisingly, she looked him in the eye and winked with a brazen

leer. She stood up and headed for the kitchen, knowing that he would

follow. When he arrived, she was busily mixing drinks. He smiled. It

was an excellent grade of scotch; he said so.

The drink relaxed him.

Laurie took the third drink in to her father. "Good for the soul," he

said to Ackerman, lifting the glass.

"It is," he said heartily.

Then Calvin Blaine drew Ackerman's story out. Blaine was genuinely

interested in the true history of the world, and enjoyed listening

to Ackerman's description of the events that took place during the

World War II and afterwards. "First hand telling," said Blaine. "It

held cards, spades, and big casino over the books." The drinks helped

Ackerman to relax, and before he knew it, the aroma of fine steak was

filling the ship.

Laurie, too, was an excellent cook.

It was, said Les Ackerman as he awoke, an eventful sixty hours since

the eventful partial explosion on his laboratory. And in twenty-six

hours since Tansie Lee had found him at six o'clock the previous

morning, Les had travelled several hundred years and a good many

millions of miles in space.

_Not bad_, he thought, _for someone who does not exist._

He stretched and turned over for another forty winks, and was dozing

when the door opened and Laurie Blaine came in with coffee, which she

held temptingly under his nose until he reached for it, and then held

completely out of reach.

"Come and get it," she said mischievously.

"I don't dare," he laughed.

"How will I know that you're getting up?" she asked suspiciously.

"Take my word for it; that smells like tomorrow morning."

"Well," she said brightly, "in case you're interested, this _is_

tomorrow morning. Get up!"

"You get out and I'll get up," he told her.

Then from the doorway, Calvin called: "Better; we're not long nor far

from the scene I want to show you."

"Good enough for me," replied Ackerman. "Drag that woman out of here,

will you?"

"Come on, shameless wench," laughed Blaine to his daughter. "Despite

your arguments, modesty is a virtue. Let the man get dressed in peace."

He grinned at Les. "She'd sit there and make snide remarks about your

knees," he said. "Git!" he told her.

She got. And Les was thoroughly awake and dressed in minutes.

After breakfast, Blaine took the controls himself. "We'll watch this

from a distance," he said. "I've enough power to break away from the

temporal inertia and attractive mass. We can see both sides of this

thing, which is more than those doing it can see."

There was the feeling of lift to the vehicle. It went on for an hour,

through the gray haze that pressed against the windows of the ship

while they were in motion. Then, finally, Blaine turned from the

controls and the haze cleared.

"I've accelerated the 'time-rate'," he said. "Now that we're out of the

earth's attractive temporal field."

"Why?"

"Destruction of anything the size of the earth takes time," explained

Blaine. "I've read stories in which the earth crashed into another

planet, and it took place in a matter of minutes. Forgetting that

at planetary velocities--earth is about seventeen miles per second

orbital, if I remember correctly--it takes the earth over a minute to

cover one diameter of motion. Also the chances of a real crash, like a

couple of golf balls colliding is impossible."

"Roche's Limit?" asked Ackerman. "They'd start to come apart by mutual

gravitational attraction before they hit, and the resulting crash would

be more like two spoonsful of baking powder hitting one another."

"Sounds messy," said Laurie.

Ackerman looked cheerfully sour. "It would be," he told her.

"This affair is not to be that simple," stated Blaine. "No collision.

Just beamed energy. Equally messy, though."

"The 'time' speed-up is obvious, isn't it?" asked Les, looking at the

distant earth through the telescope. "I can definitely perceive the

turning."

"We're running free at about twenty to one," said Blaine. "Earth will

turn once in about an hour and twelve minutes."

"When does the big show start?"

"Any moment now."

"But where's the green hazy fog?" asked Les. "I thought--"

"That fog is only apparent when near a body like earth. It is caused by

the diffraction of the air--you see, when you're moving through 'time',

the speed-up of air-motion causes a complete diffraction and diffusion

of all light. We're in space where there is no air."

* * * * *

As Blaine spoke, a twinkle of light burst like an exploding bomb a half

diameter to the north of the earth. The speckle of light spread and

diminished in intensity; it still cast a baleful but momentary glow

over the northern hemisphere--or not-quite-hemisphere because of its

proximity to the earth.

"That's the beginning," said Blaine.

Minutes later, a second pinprick of energy expanded. This one was

either on the surface or very close; it was hard to tell which. But

the effect was terrible. A ruddy gout of multicolored smoke and flame

spurted out, leaping from the point of contact. It raced up and away

from the surface making a tiny tuft of fluffy smoke that looked like a

wisp of cotton pulled through the cloth covering of a pillow. It was

tiny compared to the size of the earth, but the shock wave that raced

in a concentric circle away from the gout of energy--racing across the

ground in a crawling distortion--was quite visible. Its amplitude died

as it spread until it was invisible.

Minutes later, a contracting circle of shock-wave appeared. It

converged and closed down on the spot that was still covered by the

tiny cloud. There was considerable amplitude at that spot where all the

energy returned, then the concentric shock wave raced away from the

point again.

"I'd like to see the antipodes," muttered Ackerman.

"We'll see others," Blaine promised.

"That was the same shock wave, wasn't it?" Laurie wanted to know.

"Yes," said her father, watching through his telescope. "It started

from that city and spread out across the earth. On the other side, of

course, the thing converged to zero, passed through itself and spread

out again. It returned to its origin--and will continue to encircle

the earth until it dies. Each time it is less perfect because of

wave-diffraction and refraction due to a non-homogenous medium. That

tends to spread it out, makes its focal point imperfect. Its energy

will be dissipated in heat due to resistance. It will eventually die

and--"

"Here comes one!" exploded Laurie. "From the other side."

They watched. The shock wave converged, growing in amplitude as it

circled down to the pinpoint. There was a clouding at the focal point

where earth itself ground itself to bits in the grip of a transmitted

wave of energy. The receding wave spread out again.

[Illustration: _Fascinated, horror-stricken, Ackerman, Laurie Blaine,

and her father watched the Earth being consumed by atomic fire._]

Then, as though the enemy had been searching out their

target--bracketing it--other pinpricks burst in widely separated

places. The criss-crossing of concentric shock waves cast up high peaks

that raced along, tearing up the very ground.

"On earth," said Blaine, "Nine hours have passed since the initial

blast."

More time passed, and then with the target accurately bracketed, the

pinpricks of energy burst again and again and again in lightning

speed. The face of Terra sparkled; scintillated. The ground writhed

and boiled; mighty gouts of earth and tortured stone burst upward

where the bursts of power drove below the surface. The scintillating

face of the earth increased to a constant glow as the ferocity of the

attack increased. Moving clouds of gray and white obscured the surface,

through which came the angry, flaming glow of surface bombing by high,

sheer energy.

The color temperature of the cloud increased until the scintillating,

ever-changing illumination changed subtly. Now the smoky, cloudy earth

shone with an angry glow more bright than the individual sparkles; it

was like a fog-cloud illuminated from behind. "The earth," said Blaine

in an awesome voice, "is growing incandescent."

* * * * *

Ackerman took a deep breath. "And still," he sighed bitterly, "they

continue!"

"They will continue, until they raise the temperature of the earth

so high that the thermal energy is sufficient to exceed the escape

velocity of the earth's mass. Then, driven by the power of the

light-output, the earth will disperse in a cloud of streaming,

incandescent gas. For," Blaine added sardonically, "as the first

quantities start to leave, the mass diminishes and the escape velocity

diminishes also. The earth will expand in white-hot gas and disperse

forever."

"Horrible," said Les Ackerman through a dry and aching throat.
