The conclusion is basically (Larry) Niven's Law of Time Travel. From "The Theory and Practice of Time Travel" (1971): > If the universe of discourse permits the possibility of time travel and of changing the past, then no time machine will be invented in that universe. The entire essay is worth a read, of course. Meanwhile the paper in the OP goes for a more mathematical approach. |
