So I was thinking about an idea for a story I had, and I was wondering if I could get some other people's opinions. The idea is simple, about a person who wants to go into space. Though it is in a setting where faster than light travel is impossible so leaving Earth means leaving everyone behind and perhaps never returning and never seeing anyone they knew ever again. It would have themes of loss as well as explore transhuman ideals as they upgrade their body to better survive traveling through space.
My biggest question is, would people be interested in reading such stories? There is no crazy aliens or futuristic battles, no one is dying or being blown up. There is conflict though, it is just a very personal one, as you can suspect it would likely be hard for someone to leave Earth if they knew they would never return and never see any of the people they used to know ever again. And what would your friends and family think of it?
