<passage>:
me as you're having. Of course we have the same tastes—we're the same person. I'm you thirty years from now, or you're me. I remember just how you feel I felt the same way when he—that is, of course, I or for the first time. Some kind of telepathy seems to work between two of the same people. You sense things. So I'll simply go ahead talking for half an hour or so, until you get over it. After that you'll come along with me. You know, I could try to change things around by telling what happened to me So let's begin when you get up in half an hour and come out with me. You'll take a closer look at the machine, then. Yes, it'll be pretty obvious it must be a time machine. You'll sense that, too. You've seen and you'll be getting used to the idea that you are the man who makes it is probably the field that prevents passage through time from affecting us. The luggage section isn't protected, though. You start to say something, but by then I'm pressing a black button, it isn't there. There is exactly nothing there—in fact, there is no there . You are completely outside of time and space, as best you can guess how things are. You can't feel any motion, of course. You try to reach a hand out arm back, you're still sound and uninjured. But it looks frightening and you don't try it again. Then it comes to you slowly that you're actually traveling in time. You turn to me, getting used to the idea. "So this is the fourth dimension?" you ask. Then you feel silly, because you'll remember that I said you'd ask course, there may have been a start for all this once. There may have been a time when you did invent the machine—the atomic motor first, then the time-machine. And when you closed the loop by going back and saving yourself the trouble, it got all tangled up. I figured out once that such a universe would need some seven or eight time and space dimensions. It's simpler just to figure that this is the way time got bent back on itself. Maybe there is no machine, and it's just easier for us to imagine it. When you spend thirty years thinking about it, as apparently, though there is a time effect back in the luggage space. You look at your watch and it's still running. That means you either carry a small time field with you, or you are catching a small increment of time from the main field. I don't know, and you won't think about that then, either. time nor space, apparently. How could the air leak out? You still feel gravity, but I can't explain that, either. Maybe the machine has a gravity field built in, or maybe the time that makes your watch run is responsible for gravity. In spite of Einstein, you have always had the idea that time is an effect of gravity, and I sort of agree, still. Then the machine stops—at least, the field around us cuts off. You feel a dankish sort of air replace the stale air, and you breathe "I'm staying here," I tell you. "This is like the things they wear in this century, as near as I can remember it, and I should be able to pass fairly well. I've had all my fortune—the one you make on that atomic generator—invested in such a way I can get it on using some I'll leave you. I like the looks of things here, so I won't be coming back with you." You nod, remembering I've told you about it. "What century is this, anyway?" I'd told you that, too, but you've forgotten. "As near as I can guess, it's about 2150. He told me, just as I'm telling you, that it's an interstellar civilization." You take another cigaret from me, and follow me. I've got a small flashlight and we grope through a pile of rubbish, out into a corridor. This is a sub-sub-sub-basement. We have to walk up a flight of stairs, and there is an elevator waiting, fortunately with the door open. "What about the time machine?" you ask. "Since nobody ever stole it, it's safe." We get in the elevator, and I say "first" to it. It gives out a You get up your courage and go up to a boy selling something that might You go up the steps, but you see that it seems to be closed. You hesitate for a moment, then. You're beginning to think the whole affair is complete nonsense, and you should get back to the time machine and You work down the line. It'd be foolish to take the early model if you they're all held down by the same whatchamaycallem effect. And, finally, you're right back beside the original first model. It's probably bolted down, too, but you try it tentatively and you find it moves. There's a little sign under it, indicating you shouldn't touch it, since the gravostatic plate is being renewed. Well, you won't be able to change the time cycle by doing anything I haven't told you, but a working model such as that is a handy thing. happens, though. You stumble down the stairs, feeling all the futuristic rays in the world on your back, and still nothing happens. Ahead of you, the gate is closed. You reach it and it opens obligingly by itself. You breathe to satisfy your amiable guard friend. He finally smiles in satisfaction and heads back to the museum. You still don't believe it, but you pick up the atomic generator and closed and is moving downward in a hurry. It coughs again and you're at the original level. You get out—and realize you don't have a light. You'll never know what you stumbled over, but, somehow, you move back in the direction of the time machine, bumping against boxes, staggering here and there, and trying to find the right place by sheer feel. Then a shred of dim light appears you and the next button you touch—the one on the board that hasn't been used so far—sends you off into nothingness. There is no beam of It isn't much of a trip back. You sit there smoking and letting your nerves settle back to normal. You notice a third set of buttons, with some pencil marks over them—"Press these to return to yourself 30 years"—and you begin waiting for the air to get stale. It doesn't because there is only one of you this time. Instead, everything flashes off and you're sitting in the machine in You'll figure out the cycle in more details later. You get into the machine in front of your house, go to the future in the sub-basement, land in your back yard, and then hop back thirty years to pick up yourself, landing in front of your house. Just that. But right then, feel a little happier when you realize that the luggage space wasn't insulated from time effects by a field, so the motor has moved backward in time, somehow, and is back to its original youth—minus the replaced wires the guard mentioned—which probably wore out because of the makeshift job you've just done. that the date of the patent application is 1951. It will begin to soak in, then. You pick up an atomic generator in the future and bring it back to the past—your present—so that it can be put in the museum with you as the inventor so you can steal it to be the inventor. And you do it in a time machine which you bring back to yourself to take yourself into the future to return to take back to yourself.... kids from school are coming around to stare at the man who changed One day you come across an old poem—something about some folks calling it evolution and others calling it God. You go out, make a few provisions for the future, and come back to climb into the time machine that's waiting in the building you had put around it. Then you'll be knocking on your own door, thirty years back—or right now, from your view—and telling your younger self all these things I'm telling you. without protest, and I want to find out just why those people up there came looking for you and shouting, before the time machine left. Let's go.
