Understanding relativistic time: Exploring the concepts of spacetime and time dilation

Abstract

Relativistic time deals with concepts as spacetime and time dilation. I will try to explain this as clearly as possible. To explain the concept of spacetime is not at all impossible, although it is four-dimensional. But that means that we define it using four numbers. If we describe us through age, weight, height, and IQ, that would be a four-dimensional representation of us.
