So I'm running a superhero game on another forum and I am trying to keep comic book physics to a minimum. Problem is...I've never taken a physics class (I'm a high school student, I've taken Biology and Chem but Physics is next year). I was wondering how dark matter and dark energy work and what they are and was wondering if anyone here is kind enough to give a really simple version of what they are. I read the wikipedia article but it kind of didn't make much sense... The reason why I'm wondering is because I want to make the superhero's powers originate from a dark matter explosion passing through Earth causing latent mutations to develop. Is this too comic-book sciencey or could I work with it?
