I was just thinking about this, and from a perspective of an inertial frame, it's easy to see how distances contract, times dilate, simultaneity varies between observer and the speed of light is exactly c in each case.(adsbygoogle = window.adsbygoogle || []).push({});

But what about non-inertial frames? In the presence of gravity almost every frame is accelerated, even if we don't take GR in account so my question is what is the speed of light in those frames, and how do relativistic effects look like from the perspective of non-inertial frames, including velocities, simultaneity, time dilation and length contraction? Thanks
