I'm a relative newbie to relativity (no pun intended -- I know you've heard that one too many times), as well as to this forum, so forgive me if this is a dumb question.... As I understand it, there is a significant percentage of those that believe that people, spaceships, etc. will never travel at the speed of light (c), right? If that is so, where is my logic (below) faulty: 1. For any two given things (A and B), the speed of A relative to B will always be the same as the speed of B relative to A. 2. Relativity insists that light always travels at c relative to all things. Thus, if light is moving at c relative to me, then am I not moving at c relative to that particular beam of light (...and, in fact, all beams of light at any given moment in time)? And thus, the speed of light is not only something that is not unattainable, but has rather never been unattained? What am I missing?
