 Which isn't a feeling that the older man expects of the younger man?
There is one fact no sane man can quarrel with ... But some men aren't sane; thus it isn't always so! 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. It's a real wrench when a man meets himself for the first time. Yes, it'll be pretty obvious it must be a time machine. Doesn't hurt, and when you pull your arm back, you're still sound and uninjured. 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. When you spend thirty years thinking about it, as I did—and you will—you get further and further from an answer. That means you either carry a small time field with you, or you are catching a small increment of time from the main field. You feel a dankish sort of air replace the stale air, and you breathe easier, though we're in complete darkness, except for the weak light in the machine, which always burns, and a few feet of rough dirty cement floor around. There's no feeling of acceleration—some kind of false gravity they use in the future.
