Lorentz spacetime diagrams are a geometric way of showing motion over time where various World-lines record a faithful representation of an object's motion, as a traced out path
A Spacetime diagram purports to show how motion looks from the perspective of something which is itself moving. They represent a singular perspective when that Observer's World-Line is a situated on the straight, upright 'time- axis'.
However, there are many discrepancies with the formulation of Spacetime diagrams which allow for incorrect assumptions about time dilation and length contraction, which I will demonstrate in this essay.
