Postscript

 

YES, VIRGINIA, THERE is a superstring theory. In fact there are several, and they disagree on how many dimensions there really are—I wish the physicists would get their facts straight so I could know what I'm twisting. Nevertheless, if you want to buy a transmensor, I suggest you check with your local hyperdrive dealer.

There are string theories in cosmology, too, but they're different. That's one type of string I didn't manage to weave into the story.

The environmental stuff, unfortunately, is a lot more probable. I began this book in 1987, which turned out to be the warmest year on record, and moved the problem of atmospheric degradation out of the SF ghetto into the popular press. I'm writing these final lines near the end of 1988, which is going to be either the warmest or second warmest. By the time you read this, we'll know about 1989. I'm very glad I'll not be around to know 2050.

And without a transmensor, there's no way out.
