Hi Janus;
What happens when two moving frames move in opposite direction and each of the two frames moves with the speed of very close to the speed of light? Also to this point, let us say that observer on each of the frames shooting a beam of light towards receding frame. Imagining such a situation, one would reckon that relative velocity between the two frames is approaching twice the speed of light C. Yet the fundamental precept of the Relativity precludes such a possibility, asserting that no physical bodies can move with respect to each other with the speed greater than the speed of light C.

Unlike mass, which we can feel, the notion of absolute time is not available to us, humans. What we call TIME is a measure of passing of physical processes, of which the clock, is an instance. Humanity used a great number of artifices to mark the passing of time: astronomy, water, pendulum. The very latest

Thanks, Studiot;
But there is a rub, from this point of view two bodies are moving literaly with superlucent speed relative to each other while the math is saying they are not.
Let say an observer was put at a point where the two moving frames began their journey. This third person, stationary one, would have all the right to say that each frame move away from him at speed close to the speed of light, but moving observers would argue that they are not.
