Hello, Lately I have been wondering about the implications of the speed of light being constant for all observers, to me this seems to imply that there are different versions of reality for different observers. I will use a scenario to illustrate my reasoning. After you read this I would like people to tell me if my reasoning to come to this conclusion is valid or if it is erroneous and if so, how. Scenario: Two space ships (ship A and ship B) which are both capable of instantly attaining light speed are about to race each other while a stationary observer watches. As the race commences the observer sees the two ships racing side by side, as they are both traveling at light speed, resulting in a tie. However from the perspective of an observer on board ship A, ship B shoots ahead at light speed, winning the race. Similarly, from the perspective of an observer on board ship B, ship a wins the race. So you have three different realities for three different observers, each of which involve different race results which are summarised as follows: From the stationary observers perspective, the race is a tie From ship A's perspective, ship B wins the race From ship B's perspective ship A wins the race Please let me know if this is accurate and if not how so.
