- Leigh,
-
- Your defense of Tom has the right sentiment: listen to what he says and
- then deal with the statements as they stand.
-
- Good, I try to do that at all times. My concern would be that several
- times in the recent past he had made statements about "What are the
- actual predictions of standard, Einsteinian general relativity?" On
- points such as these, experimental information is irrelevant. It
- recovers its rightful place of primacy--the test of theories and
- models---only when there is clear understanding of what the theories
- and models actually say. I believe the response to Tom has been mostly,
- not what do the binary pulsar results say about the existence of
- gravitational waves at all, but *in the case* that one takes Einsteinian
- GR as a working model, can it be fit to the data, and if so, what does
- it say about the phenomena. Remember that, unlike the "standard model",
- either in particle physics or in cosmology, GR is a rigorous theory,
- and very precise statements can be made on what it says about the
- nature of space-time, given the appropriate boundary conditions, e.g.,
- presence or absence of incoming or outgoing waves. Much of the criticism
- that has hit home against Tom's modelling has been in this direction:
- attempts to claim that this or that model (usually cosmology, where
- things are more debatable, but now this time in Einsteinian GR, where
- they are really not) is false, based on incorrect statements on what this
- or that model actually predicts. Forget about the track record, the
- statement that there are no gravity waves in Einsteinian GR is simply not
- true.
