Can anyone tell me what exactly do the variables "Time Dilation" and "Velocity of a fraction of the speed of light" represent (in this graph) from the lorentz contraction?(adsbygoogle = window.adsbygoogle || []).push({});

Does the x-axis represent "v/c" or is it "v^2/c^2"? What does the y-axis represent? Which "t"? Or is it one "t" over another?
