Participants in the Sci-Fi workshop might know I'm writing a short story there, and I've come up against some interesting thoughts. Register to remove this ad Space travel, specifically zero gravity, has a detrimental effect on the human body. This fascinated me since it's not something I've seen addressed in a lot of Sci-Fi movies. (They've all got gravity.) Now there's a lot of places in my story where I want to put little scientifically relevant bits like this. Aerodynamics for example. And I was just wondering, (if there's any sci-fi writers) how far you're comfortable stretching the bounds of science? Do you go for faster than light travel? Warp Speed? Wormholes? Do you have gravity machines? Does your protagonist make sweet sweet love to every alien female he comes across regardless of physical attributes or feasibility?
