excuse me, I mispoke it's clearly a dimension of 5 vectors

Such an issue is valid since the divergence of an electro- magnetic energy-stress tensor ∇c T(E)cb (where ∇c is a co- variant derivative) generates only the Lorentz force, whereas the divergence of a massive energy-stress tensor ∇c T (m)cb would generate the geodesic equation [9].
Thus, the energy-stress of photons T (L)ab would be T(L)ab =T(E)ab +T(N)ab (1)
or
T(N)ab =T(L)ab −T(E)ab
where T (E )ab and T (N )ab are respectively the electromag- netic energy-stress tensor and a non-electromagnetic energy- stress tensor. Besides, being intrinsically traceless, T(E)cb would not be compatible with Einstein’s formula △E = =△mc2. Based on the fact that the electromagnetic energy is dominating experimentally, it is natural to assume as shown later that T(N)ab is in fact the gravitational energy-stress tensor T (g)ab .
