Re: New version of a relativity FAQ

Juan R. says...

So Juan's argument, that NC cannot be equivalent to Newtonian gravity
because no metric theory can be, is nonsensical, since NC is not a
metrical theory. It shows that he doesn't know what he is talking about.

I am not sure what impresses me more: i) how some people can built a
argumentative tower over a misreading of that other is really saying or
ii) the clever capacity to evaluate works 'at-a-distance' (i.e. without
reading them first).

I'm not making a judgement about your paper. I'm making a judgement
about what you said in sci.physics.relativity. What you said was incorrect.
Newton-Cartan is *not* a metric theory of gravity. Can you at least
either (1) acknowledge that you mispoke, or (2) explain why you
think Newton-Cartan is a metric theory of gravity.
