I have recently began to read about special relativity. I think I've got a decent grasp of how it works, but I have been confused on one point. Let's say you are in a spaceship going along at some constant velocity. If you fired a laser beam out into space you would see it moving at 300,000km/sec. Now, in order to observe this, wouldn't you have to be moving at zero speed? It seems to me that space would have to dilate to infinitely long and/or time dilate to infinitely slowly for you in order for you to be able to achieve results like this. I know that the finite speed of light in any reference frame is a proven fact but I just can't seem to visualize it in a scenario that makes sense to me.(adsbygoogle = window.adsbygoogle || []).push({});
