Teoria speciala a relativitatii se aplica acolo unde miscarea este in linie dreapta si uniforma. Nu in cazul miscarilor circulare.

"Special relativity includes only the special case (hence the name) where the motion is uniform. The motion it explains is only if you’re traveling in a straight line at a constant speed.
As soon as you accelerate or curve — or do anything that changes the nature of the motion in any way — special relativity ceases to apply. That’s where Einstein’s general theory of relativity comes in, because it can explain the general case of any sort of motion."
Iar despre citat, ti-am dat pagina din cartea lui Max Born. Acolo e scris negru pe alb ca pamantul fix e la fel de bun ca oricare alt sistem de referinta. Ce vrei sa-l scol din morti pe Einstein sa-ti spuna el acelasi lucru ? Pai a spus-o si el. :)
