I didn't refer to (not yet experimental verified) gravitational
waves but to the meaning of the energy-momentum tensor
according to gravity, that describes the energy density
of a bit of spacetime and that might also consist even
alone of an electromagnetic field (radiation, no matter).
Gravity both is caused and applies to (massless) fields
the same way than to matter (fields). Gravity is entirely
self referential.
