Another day, another "it's #scifi, it doesn't need to be realistic!" argument. Therefore, another canned reply.

The first word in "#science #fiction" is "science." As both a scientist and #SF writer, I really appreciate it when writers put as much thought into making their work as credible as possible, and try to do the same in my own. Break whatever rules you need to tell the story you want (faster-than-light travel, #aliens that can cross-breed with humans, whatever) but don't ask readers to *unnecessarily* suspend their disbelief.

Or as the saying goes in fantasy, "If you want me to believe in #dragons, get the #horses right."

... now I suppose I should really get back to either writing science fiction or doing science, because deadlines are absolutely part of the here-and-now.
