Science fiction stretches our minds and imaginations by presenting the possibility of new worlds full of very different beings and fantastic technology. Some stories are wondrous and hopeful, while others are terrifying and make us glad to be where we are instead. What kinds of these stories do you like best? We often see plots, twists, and tropes used over and over, mainly because they thrill us and make us want to revisit these worlds. Sure, they often require a lot of suspension of disbelief, but we’ve become accustomed to that in order to be entertained.
