it doesn't all depend on what "is" is.) I think non-locality in QM
contradicts the standard interpretation of GR, specifically the notion
that there is no preferred frame.
The Alcubierre idea shows that even this might not necessarily be the
case, though to me the "fix" is weirder than the problem it's supposed
to fix. But that's more of an emotional assessment than a scientific
one, so I certainly regard the issue as open and deserving of more
The most one can say at present is that qm and gr are consistent to
whatever extent each of them is true. If either or both are saddled
with some false interpretation, then one may find what looks like
inconsistencies. But once the correct (realist) interpretations are
discovered, everything will be consistent because there is only one
