1. The problem statement, all variables and given/known data 1. You observe two events to occur simultaneously. A friend is moving with respect to you. The friend will see : The event the friend is moving towards occurs first, in their perspective The order of the events is random and cannot be predicted The events occur simultaneously, but at a different time than according to your clock The events occur simultaneously according to all observers 2. How well tested is Special Relativity? : It is complete speculation It has recently failed some very significant tests It has been extremely accurately and rigorously tested for over 100 years Some aspects have been rather well tested 2. Relevant equations None 3. The attempt at a solution For 1, I think the answer is "The event the friend is moving towards occurs first, in their perspective" For 2, I think the answer is "Some aspects have been rather well tested"
