I have been confused for a long time now on one of the aspects of special relativity, which says that all motion is relative and all objects have an equal right to claim being at rest, and also the idea that an object can never go faster than the speed of light. Therefore, if an object were moving at nearly the speed of light away from another object, it would not be able to accelerate much more. But what if, then, a third object was moving away from the second object in the opposite direction. For the object in the middle, neither object would seem to be violating the speed of light speed limit, but the two objects at either end would be moving at faster than the speed of light relative to one another, which should not be possible. This can be taken to a larger scale by thinking about all the different objects in the universe moving away from each other. This would make it seem that it would be hard to accelerate very much in any direction without moving faster than the speed of light away from something in the universe. What\'s the explanation for this?
