Article-I.D.: iheds.212 Posted: Mon Feb 21 13:01:36 1983 Received: Tue Feb 22 05:11:46 1983 Reply-To: gjphw@iheds.UUCP (Not really, but: Patrick Wyant) References: sri-arpa.453 aluxz.1107 alice.1508 aluxz.1108 Most of the comments of late about General Relativity (often called Einstein Theory to distinguish it from other relativity theories) mention what GR says. The equivalence between mechanics in a gravitational field and in accelerating reference frames is an assumption in Einstein Theory and not a consequence of it. And, since Einstein Theory has received only three significant tests (passing them all quite well, though), this equivalence assumption may still not be valid. Patrick Wyant Bell Labs IH *!iheds!gjphw
