There are other formulations of relativity which aren&#x27;t nonlocal!!  Like the Tangherlini transformations.<p>I like this quote:<p>&quot;Alice wants to synchronize her clock with Bob&#x27;s, so this is how it might go:<p>At 12:00:00 pm Alice time, Alice sends out a beam of light to Bob, as a signal for Bob to tell Alice what time he has.<p>Once Bob receives the beam of light, Bob immediately sends Alice a beam of light telling her the time he has.<p>At 12:00:02 pm Alice time, Alice receives Bob&#x27;s time, say 11:41:23 am.<p>At this point, how should Alice synchronize clocks? Clearly, 12:00:01 pm Alice time is 11:41:23 Bob time. We&#x27;re done.<p>But we&#x27;ve unknowingly introduced an assumption here, namely that the speed of light travelling from Alice to Bob is identical to the speed of light travelling from Bob to Alice.&quot;
