My thought on this is that the notion of time as a dimension does not have anything to do with the stacking dimension. In fact, I don’t think they can be the same dimension because that would imply that there is nothing to distinguish a point in our space-time continuum from a point with the same space-time coordinates in some other continuum.
P.S. I also didn’t care for the president’s solution to the story’s problem.
The story ends with a challenge to the reader with a total of $50 in cash prizes for the best answers! The answer to the challenge was given in the June issue. Somehow in the answer, George Worthey’s name changed to Sherwin, but I think that was just an editorial mistake. I didn’t much care for Farley’s “correct” answer, although I did spot Isaac Asimov’s name listed among the 112 correct respondents in the July issue. The contest winner was Albert F. Lopez from East Boston, Mass.
Your answer should be based on the facts of time travel and its rules, as stated in the story by Professor Tyrrell. Your editors suspect that the correct answer would also shed light on the fate of the Professor’s friend in Holland—rather FROM Holland. But of course, there is a little of George Worthey in all of us, and you may not believe this. Editors don’t know it all, either—
Except that Ralph Milne Farley has kindly supplied us with the answer, and we know it and believe it. We’ll give it to you in the next issue, what’s more, and they you’ll believe it too.
