I’m a believer in Sturgeon’s law, but why must bad SF be so very bad? Especially when written by non-scientific sorts, as in my latest literary conquest, The Smithsonian Institution by Gore Vidal. This is a truly lamentable alternate history wherein the main character goes back in time to prevent World War II, all the while cavorting with a President’s wife in Gore’s so-bad-they-are-amusing love scenes which always end, “he entered her.” Now of course time travel is a stretch, yet I didn’t think anyone could do it worse than Michael Crichton. Alas, try this garbage on:
The light string, enormously magnified, could pinpoint any instant in space-time. The theorem that he had devised for Dr. Oppenheimer to keep one detonating atom from setting off random explosions within other atoms could also be adapted to provide sufficient velocity for a human being to go either backwards or forward in time and, once located in the desired space-time, he would be able to synchronize with the speed of those already there for a limited period — the limitation being the amount of power he could produce to provide him with sufficient velocity needed to do what he had to do and return to his home time-space.
Ahh, it is so clear now: use string theory! And um, some theorem, and do something else and go really fast and add power… and you need to use the time-space, or space-time, or whatever that jigger is. Easy.
