Or, the best assumption of simultaneity becomes at observation. For once the intuitive answer and the maths agree. | |

We know that if speed goes a roundtrip, it will always finish that in the same amount of time. It is just convenient to think/believe that it goes both directions the same speed, but it is currently not provable. See this video for a thorough explanation: youtu.be/pTn6Ewhb27k | |
