Relativistic Mass as "Gravitational Charge"
I've just made a new page for the GR portion of my web site. In it I derived Einstein's field equation but with a different slant. I've decided to go with the "relativistic mass" as source of the gravitational field rather than the "energy as source" view. As such I used the mass tensor, M, that I defined here
http://www.geocities.com/physics_world/sr/mass_tensor.htm
The difference being only a constant of proportionality. The relationship between the mass tensor M and the energy-momentum tensor T is analogous to the relation E = mc2. The difference in meaning of these tensors is analogous to the question as to whether 4-momentum should be defined as
P = (mc,p)
or as
P = (E/c,p)

Relativistic mass, aka mass-energy, plays the role of a gravitational charge in general relativity.
Of course this is exactly what is meant in Gravitation, Misner, Thorne and Wheeler, on page 404

Mass is the source of gravity.
