A spacetime diagram is a diagram that shows the effects of special relativity. It looks like a rectangular coordinate system, with the vertical axis being "ct" (speed of light multiplied by time) and the horizontal axis being "x" (position).
Spacetime diagrams are often used to validate relativity (by demonstrating that the paradoxes of relativity are not actually paradoxes.) However, the whole concept of the spacetime diagram is constructed from relativity itself. Therefore, the logic is circular; spacetime diagrams do nothing to prove relativity.
