Sorry to hear that, Admin.
I think that comment is a bit of a compliment in disguise. Astounding in the 1940's was a groundbreaking publication. I do agree, however, that the trend in science fiction is very much away from "hard" s.f. and towards "science as a setting, not as a driving idea." Maybe you should write a vampire romance. In space.
I'm an English major, as it happens, and while I thoroughly enjoy, say, Harlan Ellison, I also thoroughly enjoy Arthur C. Clarke.
Best of luck with "One Way." Hope you find a home for it.
