Message-ID: <398@sri-arpa.ARPA> Date: Mon, 15-Jul-85 13:01:30 EDT Article-I.D.: sri-arpa.398 Posted: Mon Jul 15 13:01:30 1985 Date-Received: Wed, 17-Jul-85 20:56:32 EDT Lines: 9 From: Doug Gwyn (VLD/VMB)What I really had in mind in the (A E B spaceship) thought experiment was that observer A would be doing something nonsymmetric with respect to the two spin states, so that there would be a way of telling whether he had "interfered" with what is going on at observer B. Perhaps this is not possible, which would save the situation in the way you describe, but offhand it is hard to see why not..
