Dark Matter is a theoretical form of invisible mass, which has never been definitively detected. You've probably heard of it before, as it makes up a large part of the physics you find in textbooks. But how can something that's never been seen have so much scientific confidence behind it? Furthermore, if we can't see it, how do we know that it is really there? And if it's not, what are the alternative explanations? These are the questions we will be aiming to answer, as we delve into the Dark Matter mystery.
