For a long time, humans have perceived time and space as separate concepts. Scientists in classical mechanics considered time to be absolute when calculating the speed of light. In the early 20th century, Einstein proposed a space-time concept that integrates time and space into one through the theory of relativity. The fact that time expands and space contracts for objects with mass was a concept that was difficult for humans to intuitively understand. With this theory, the way humans understand time, space, matter, and the theory of physics it- self changed. Minkowski's space-time is a mathematical model of space-time that well de- scribes Einstein's theory of relativity. In this space, three-dimensional space and one-dimen- sional time are combined to express four-dimensional space-time.
