This lab illustrates the concept of the Minkowski Spacetime.

Minkowski spacetime (or Minkowski space) is a coordinate system devised by German mathematician Minkowski. The peculiar thing is that the coordinate system contains space and time.

Minkowski spacetime uses matrices to express a four-dimensional coordinate system (x, y, z, ct) by integrating three-dimensional space and time. However, because 4D matrices are very complex, they usually only deal with motion in one axis (e.g., the x-axis). Then, the horizontal axis became the x-axis of space, and the vertical axis became the y-axis of time(x, ct).

Minkowski spacetime makes it easy to explain time dilation phenomena according to 'Special Relativity,' such as the 'twin paradox.'
