A spacetime diagram is a graphical illustration of the properties of space and time in the special theory of relativity. Spacetime diagrams allow a qualitative understanding of the corresponding phenomena like time dilation and length contraction without mathematical equations. The history of an object's location throughout all time traces out a line, referred to as the object's world line, in a spacetime diagram. Points in spacetime diagrams represent a fixed position in space and time and are referred to as events. The most well-known class of spacetime diagrams are known as Minkowski diagrams, developed by Hermann Minkowski in 1908. Minkowski diagrams are two-dimensional graphs that depict events as happening in a universe consisting of one space dimension and one time dimension. Unlike a regular distance-time graph, the distance is displayed on the horizontal axis and time on the vertical axis. Additionally, the time and space units of measurement are chosen in such a way that an object moving at the speed of light is depicted as following a 45° angle to the diagram's axes. (Wikipedia).
Spacetime Diagrams: An Easy Way to Visualize Special Relativity (Physics by Parth G)
If you've seen a distance-time graph before, you'll pick up spacetime diagrams very quickly... and understand their true power in visualizing special relativity! A spacetime diagram is any diagram that shows the behavior of an object through space and time. However, the term most commonly

What the HECK is Time?! (in Einstein’s Relativity)
In special and general relativity, we imagine time as just another dimension of space in something called "spacetime." Unfortunately, this picture leads to questions about determinism and free will. Is that really how it works? What does the concept of spacetime actually say about the univ

Special Relativity Intro: Reference Frames & Spacetime Diagrams
Special relativity gives us a powerful new way to think about physics. In order to apply special relativity, we first have to understand coordinate systems! Here we talk about defining coordinate systems using rulers and clocks, as well as using spacetime diagrams to draw world lines. Spe
