Dear Vladimir,
Knew you'd like the elephant!
The vector v is the velocity of the local mass (actually mass density, rho) so that the combination (rho)(v) is momentum density. The existence of momentum density then (according to Maxwell's, Einstein's, and my own equations) gives rise to a circulating gravitomagnetic field exactly analogous to the manner in which a charge current density gives rise to electromagnetic field circulation. 'v' can be any (nonzero) velocity up to the speed of light.
I agree that Smolin has done an excellent job of analyzing current problems. [Not so good on solving them.] The one you quoted is very important.
As for energy and mass, I'm not sure I can satisfy you. The current belief, which I share, is that the energy of the field does have "mass equivalence" and does gravitate. You may be asking about 'matter' which I tend to think of as "condensed mass".
All theories have to have some basic 'substance' or 'field' or 'something' since no one knows how to derive a real physical universe from 'nothing' (although I think that's what the Platonists are striving for.) In my theory it's gravity. I feel it, it acts on me, it's real. Rather than derive gravity from some imaginary field, I simply accept it as real and try to derive everything else from that reality, starting only with the idea that it must evolve, since our current condition is not the initial or original condition of the universe.
In my earlier essays I developed the aspect of there being initially nothing but gravity. In other words the energy of the gravitational field itself is the only mass in existence. This may seem tricky but I am unaware of any theory of creation of the universe that is absolutely straightforward. If one accepts this hypothesis, everything follows from there. One has to start with something and I start with one field, the gravitational field, and one condition, that it can only evolve through self interaction. All of my essays are based on this hypothesis, which is essentially what Eugenio Calabi also based his theory on.
I have, in the basic C-field circulation equation, suppressed the minus sign by incorporating it into the kappa coefficient. This sign makes the circulation left-handed (which it actually is.) You have a good eye for visual detail.
Your question about Chardin is on target, but I do not propose a mystical field that *envelops* the physical one. It *is* the physical one, properly understood. Self interaction implies, to some extent, self-awareness. That is the Participatory Universe Wheeler proposed. It started as One, Not-two, and evolved to our current state.
Thank you for your interest and your well wishes.
