question:  Which isn't something the guard did?
context: There is one fact no sane man can quarrel with ... You will, you know, so why quibble about it? At least, you always have ... or do ... or will. And naturally, since we have the same tastes, you can make the same for me as you're having. Some kind of telepathy seems to work between two of the same people. Yes, it'll be pretty obvious it must be a time machine. You start to say something, but by then I'm pressing a black button, and everything outside will disappear. You are completely outside of time and space, as best you can guess how things are. Doesn't hurt, and when you pull your arm back, you're still sound and uninjured. "Maybe it's no dimension—or it might be the fifth; if you're going to skip over the so-called fourth without traveling along it, you'd need a fifth. If you don't, it's a good way of going crazy. I figured out once that such a universe would need some seven or eight time and space dimensions. Maybe there is no machine, and it's just easier for us to imagine it. Anyhow, you sit there, watching nothing all around you, and no time, apparently, though there is a time effect back in the luggage space. That means you either carry a small time field with you, or you are catching a small increment of time from the main field. Maybe the machine has a gravity field built in, or maybe the time that makes your watch run is responsible for gravity. "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. He told me, just as I'm telling you, that it's an interstellar civilization." There's no feeling of acceleration—some kind of false gravity they use in the future.
