Hi all, After reading about Einstein's theory of relativity I have few questions as follows 1. Lets say I am in a space lab which is traveling at the speed of half of the speed of light. So when I try to measure the speed of light coming from space I record it as 'c'. Time is running slow (half with respect to stationary frame) in side of space lab, so if I conduct the experiment to measure the speed of light inside the space lab what result will I get, remember time has slowed to half. 2. Gravity is curvature in space caused by mass right? Then that curvature should be constant for all other small masses. That means photon follow the path along the curvature caused by huge mass. So if earth is rotating in its orbit around the sun due to curvature in space caused by sun, then if I point a laser in space in the direction of earth's orbit, shouldn't the photons of laser should also travel along with that curvature and start orbiting sun? Forgive me if these questions are asked earlier and guide me to that thread. Thanks in advance.
