I love space. I am absolutely obsessed with outer space, exoplanets, and various other things that I don’t fully understand because I don’t science for a living or even go to school to learn how to science. But as someone who reads every science journal I can get my hands on about space and the possibility of extraterrestrial life, I think I’ve reached the point where I have at least a rudimentary understanding of things like gravity. Since I find science super fun, I’ve always been interested in exploring it through a fictional medium where I can vicariously travel to different planets and meet alien life. Stargate, Star Wars, Star Ocean, the new Star Trek movies—why do so many titles have Star in them?—and even Dark Matter and Jupiter Ascending are all right up my alley.

But one of the things that has always annoyed me about these stories is the lack of variety on the planets they go to visit. This is significantly less true for Star Wars and Star Trek, which feature a wide array of alien life and habitats, but in the end, the only way I can conclude that physics works the way it does in too many of these stories is because of magical plot convenience.
