Master of Space and Time by Rudy Rucker

fly.” I looked around for my goodies. And there they were, right under me, packs and packs of twenties and hundreds and five hundreds, a whole mattress of them! And next to my money-bed was a small wood box containing, no doubt, a simply reproducible device for turning dirt into food, just like I’d asked Harry for. Harry?
    I hurried over to the blunzing chamber and dragged the big door open. “Harry!”
    There he was, standing in the middle of the blunzing chamber. The hotshot table was gone. Harry was standing there with a swarm of little Harrys in the air around him. The little Harrys were all sizes, numberless as a column of spring gnats.
    â€œHoly science, Harry! You really did it!”
    â€œI’ve already done the trip back to Friday, and the lizard’s trip, and I made your money and Nancy’s cure for world hunger, and I moved the hotshot table out of the way.” I noticed the table standing off to one side of the room. “And I fixed Antie—”
    â€œWhat about me?” interrupted Sondra. “Flying milk van. I don’t like it, Harry.”
    â€œWell, I do.” Excitement parted his big lips. He stepped out of the blunzing chamber and looked around. “I like it this way.” The swarm of little Harrys followed him out of the chamber.
    â€œWhat are those things?” demanded Sondra. “Bugs?”
    â€œThey’re little copies of me. There’s infinitely many of them. It has to do with the renormalization problem and the existence of multiple solutions to the Schrödinger wave equation.”
    â€œThey’re little people?” said Sondra, stepping closer. She reached out a finger and one of the little Harrys landed on it. “How cute!”
    â€œI can use them as scouts,” said Harry. “That’s what I’m going to do now.” He herded the buzzing school of little Harrys back into the blunzing chamber, closed the door, and stood outside with his head pressed against the door. A minute passed, and another.
    â€œThere,” Harry said finally. “It’s done. Six worlds meet. Go on and look.”
    He stepped aside and I swung the blunzing chamber’s door back open. What I saw inside was impossible. Somehow each of the cube’s six faces were now an open door. I staggered and almost lost my footing.
    Six doors to six places:
    1. The room around us: Here and Now.
    2. Globs and happy squiggles: The Micro world.
    3. An endless meadowed mountain: Infinity.
    4. Glowing robots on the moon: The Future.
    5. Strange merging shapes: Hyperspace.
    6. A room like ours, but upside down and backwards: Looking-Glass World.
    From where I stood, Door No. 2 was to the left and Door No. 3 to the right. Door No. 4 was where the blunzing chamber’s floor had been, and Door No. 5 was on the chamber’s ceiling. Straight across the chamber was Door No. 6. Door No. 1, of course, was the original door, the door I stood outside.
    The swarm of tiny Harrys buzzed fretfully, darting in and out of the six magic doors.
    â€œLet’s go,” said the big Harry at my side. “Come on, Fletch, I want to jump across to that world on the other side.”
    â€œForget it, man. I want to take my money back to Nancy before—”
    â€œOh, you’ve got your five million bucks and that’s it, huh? Only so far and no further, right? What are you going to buy, Fletcher? What’s going to be as good as this?”
    I looked to Sondra for support. She was staring into a mirror, running her fingers over the curves of her new face.
    I tried again. “Harry, those doors look really exciting. Hyperspace, size change, parallel worlds—it looks really neat. But I’m not going to risk everything just for some crazy science fiction thrills.”
    â€œI can still make your money disappear, Fletcher. I can put you back inside an endless regress like before.”
    â€œYou don’t want to do that, Harry.
