Why can’t we reach the speed of light? - Velocity addition theorem gives the answer|@PhysicsNextBook

Описание: In this video we explain why speed of light is the maximum and no object can go any faster. An alternative way to state this is "no inertial observer can observe an object move faster than light". We demonstrate this by using the velocity addition theorem which we show how to derive from the Lorentz transformation equations of special relativity in a few simple algebraic steps.
