| Video Discription | Dark Matter is a theoretical form of invisible mass, which is believed to be present in galaxies, but has never been seen or 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? Furthermore, why can't we see dark matter to begin with? And if we can't see it, how do we know that it is really there? And if it's not there, what are the alternative ideas? These are the questions we will be aiming to answer, as we dive into the Dark Matter mystery. The soundtrack was created by SpaceWave - Cosmic Relaxation.
