History is a part of all science|I will mention some of the relevant events in the development of special relativity|but there is no attempt to present the material in a historical way. In this video, w Lagrangian mechanics can indeed be used in special relativity too, but the Lagrangian for that is not T-V, it rather looks something like this (this Lagrangian is explained in my introduction to special relativity): L=-mc^2\sqrt{1-\frac{\dot r^2}{c^2}} The generalized momentum for this is: The disparity resulted from the speed of the planes (a special relativity effect) and their greater distance from the center of Earth’s gravitational field (a general relativity effect). Special relativity is based on two fundamental principles; the constancy of the speed of light and the universality of the laws of physics, which lead to the ideas of spacetime and 4-vectors. Time dilation is the idea that as you move through space, time itself is measured differently for the moving object than the unmoving object. org/science/physics/special-relativity/.
