Hello everyone, I've been creating this fictional universe for my space opera for close to 3 years now. I'm very enthusiastic about my world, but what I am finding extremely frustrating are certain aspects of world building. Specifically the whole "be true to science" part. Actually come to think of it, I am sick of this in more areas than just world building. Now I understand the genre gives leeway to certain fantastical elements (i.e. FTL travel). The thing is, I just don't really care enough to do the in-depth research necessary to create realistic settings in space. I like space as a setting (or maybe my fantastical view of space) but I don't care 1 iota for spending anymore time looking at astrophysics textbooks or consulting things like project rho. Just as an example, I've been recently trying to come up with the details for an orbital space station that houses nearly 3 million people. I've spent several hours researching dimensions, shape, what type of orbital period is possible around what type of star, etc. and I'm just tired of it. The same goes for my space ships, my planets, and even some of the technology in general. Would it be such a bad thing if I just hand-waved the vast majority of this stuff? At what point does sci-fi become fantasy? I myself am a 2nd year M.D. student with a master's degree in physiology (i.e. a very heavy science-related background). But I write because I like to engage the creative side of my brain, and the heavy physics research to maintain a level of purity is something I find myself unwilling to do anymore.
