I have been reading a book on quantem reality over the Yule holiday, and came up with a simple question that I'm sure someone here can answer. My question is this: If an object is approaching me from one direction at .9c, and another object is approaching me from the opposite direction at .9c, it would seem to me that relative to the first object, the second object would be moving at 1.8c. Since nothing can move faster than c, this is thus impossible, yes? But if that is the case, then it would follow that from my initial position neither of those two objects could be approaching me at a greater combined speed than c. This does not appear to work. What gives? Thanks, Eric
