Special Relativity And The Curious Physics of Chronology:
Einstein showed that two unrelated events can appear in any order depending on your point of view. Now physicists have discovered the chronologies of three events, and more
Special relativity has changed the way we think about time and the order of events. Einstein famously showed that two events can look simultaneous to one observer but not to another. In fact, it's possible to make two spatially separated events appear in any order by choosing to view them from different frames of reference .
