sorry to bring this up again, i have just started special relativity and the constancy of c is a bit confusing, i get how c is the same in all inertial frames but what about accelerating frames? do observers in acceleration still see c as a constant? i have seen many forum posts and they always have two people saying the opposite things, can somebody set me straight on this?(adsbygoogle = window.adsbygoogle || []).push({});

also, if the observer is moving at 0.99c and he will see c still being c, but what about a stationary observer looking at both? will he see both of them travelling almost at the same speed?
