I have heard about Einstein's theory of special relativity but never really understood it, so I watched some YouTube videos.
I think I have a grasp of its basic ideas but there is a nagging question that I can't really find the answer to.
Special Relativity states that the faster and object is moving, the slower time is from its point of view. However, when there's know object of reference, you can't know which object is moving and which is not. So what decides an object's speed, and it's perception of time?
