What sort of games? That's simple enough to explain. Since space was curved, we sent the atoms rolling along its curve, like so many marbles, and the kid whose atom went farthest won the game. When you made your shot you had to be careful, to calculate the effects, the trajectories, you had to know how to exploit the magnetic fields and the fields of gravity, otherwise the ball left the track and was eliminated from the contest.
The rules were the usual thing: with one atom you could hit another of your atoms and send it farther ahead, or else you could knock your opponent's atom out of the way. Of course, we were careful not to throw them too hard, because when two hydrogen atoms are knocked together, click! a deuterium atom might be formed, or even a helium atom, and for the purposes of the game, such atoms were out: what's more, if one of the two belonged to your opponent, you had to give him an atom of your own to pay him back.
You know how the curve of space is shaped: a little ball would go spinning along and then one fine moment it would start off down the slope and you couldn't catch it. So, as we went on playing, the number of atoms in the game kept getting smaller, and the first to run out of atoms was the loser.
Then, right at the crucial moment, these new atoms started cropping up. Obviously, there's quite a difference between a new atom and a used one: the new atoms were shiny, bright, fresh, and moist, as if with dew. We made new rules: one new was worth three old; and the new ones, as they were formed, were to be shared between us, fifty-fifty.
In this way our game never ended, and it never became boring either, because every time we found new atoms it seemed as if the game were new as well, as if we were playing it for the first time.
Then, what with one thing and another, as the days went by, the game grew less exciting. There were no more new atoms to be seen: the ones we lost couldn't be replaced, our shots became weak, hesitant, because we were afraid to lose the few pieces still in the game, in that barren, even space.
Pfwfp was changed, too: he became absent-minded, wandered off and couldn't be found when it was his turn to shoot; I would call him, but there was never an answer, and then he would turn up half an hour later.
"Go on, it's your turn. Aren't you in the game any more?"
"Of course I'm in the game. Don't rush me. I'm going to shoot now."
"Well, if you keep going off by yourself, we might as well stop playing!"
"Hmph! You're only making all this fuss because you're losing."
This was true: I hadn't any atoms left, whereas Pfwfp, somehow or other, always had one in reserve. If some new atoms didn't turn up for us to share, I hadn't a hope of getting even with him.
The next time Pfwfp went off, I followed him, on tiptoe. As long as I was present, he seemed to be strolling about aimlessly, whistling: but once he was out of my sight he started trotting through space, intent, like somebody who has a definite purpose in mind. And what this purpose of his was – this treachery, as you shall see – I soon discovered: Pfwfp knew all the places where new atoms were formed and every now and then he would take a little walk, to collect them on the spot the minute they were dished up, then he would hide them. This was why he was never short of atoms to play with!
But before putting them in the game, incorrigible cheat that he was, he set about disguising them as old atoms, rubbing the film of the electrons until it was worn and dull, to make me believe this was an old atom he had had all along and had just happened to find in his pocket.
And that wasn't the whole story: I made a quick calculation of the atoms played and I realized they were only a small part of those he had stolen and hid. Was he piling up a store of hydrogen? What was he going to do with it? What did he have in mind? I suddenly had a suspicion: Pfwfp wanted to build a universe of his own, a brand-new universe.
From that moment on, I couldn't rest easy: I had to get even with him. I could have followed his example: now that I knew the places, I could have gone there a little ahead of him and grabbed the new atoms the moment they were born, before he could get his hands on them! But that would have been too simple. I wanted to catch him in a trap worthy of his own perfidy. First of all, I started making fake atoms: while he was occupied with his treacherous raids, I was in a secret storeroom of mine, pounding and mixing and kneading all the material I had at my disposal. To tell you the truth, this material didn't amount to much: photoelectric radiations, scrapings from magnetic fields, a few neutrons collected in the road; but by rolling it into balls and wetting it with saliva, I managed to make it stick together. In other words, I prepared some little corpuscles that, on close inspection, were obviously not made of hydrogen or any other identifiable element, but for somebody in a hurry, like Pfwfp, who rushed past and stuck them furtively into his pocket, they looked like real hydrogen, and spanking new.
So while he still didn't suspect a thing, I preceded him in his rounds. I had made a careful mental note of all the places.
Space is curved everywhere, but in some places it's more curved than in others: like pockets or bottlenecks or niches, where the void is crumpled up. These niches are where, every two hundred and fifty million years, there is a slight tinkling sound and a shiny hydrogen atom is formed like a pearl between the valves of an oyster. I walked past, pocketed the atom, and set the fake atom in its place. Pfwfp didn't notice a thing: predatory, greedy, he filled his pockets with that rubbish, as I was accumulating all the treasures that the universe cherished in its bosom.
The fortunes of our games underwent a change: I always had new atoms to shoot, while Pfwfp's regularly missed fire. Three times he tried a roll and three times the atom crumbled to bits as if crushed in space. Now Pfwfp found one excuse after another, trying to call off the game.
"Go on," I insisted, "if you don't shoot, the game's mine."
And he said: "It doesn't count. When an atom is ruined the game's null and void, and you start over again." This was a rule he had invented at that very moment.
I didn't give him any peace, I danced around him, leaped on his back, and chanted:
"Throw it throw it throw it
If not, you lose, you know it.
For every turn that you don't take
An extra throw for me to make."
"That's enough of that," Pfwfp said, "let's change games."
"Aha!" I said. "Why don't we play at flying galaxies?"
"Galaxies?" Pfwfp suddenly brightened with pleasure. "Suits me. But you… you don't have a galaxy!"
"Yes, I do."
"So do I."
"Come on! Let's see who can send his highest!" And I took all the new atoms I was hiding and flung them into space. At first they seemed to scatter, then they thickened together into a kind of light cloud, and the cloud swelled and swelled, and inside it some incandescent condensations were formed, and they whirled and whirled and at a certain point became a spiral of constellations never seen before, a spiral that poised, opening in a gust, then sped away as I held on to its tail and ran after it. But now I wasn't the one who made the galaxy fly, it was the galaxy that was lifting me aloft, clinging to its tail; I mean, there wasn't any height or depth now but only space, widening, and the galaxy in its midst, also opening wide, and me hanging there, making faces at Pfwfp, who was already thousands of light-years away.
Pfwfp, at my first move, had promptly dug out all his hoard, hurling it with a balanced movement as if he expected to see the coils of an endless galaxy open in the sky. But instead, nothing happened. There was a sizzling sound of radiations, a messy flash, then everything died out at once.
