  Now, it is already not a big surprise that due to the spontaneous Lorentz
invariance violation (SLIV) there may emerge massless vector and tensor
Goldstone modes identified particularly with photon and graviton. Point is,
however, that this mechanism is usually considered separately for photon and
graviton, though in reality they appear in fact together. In this connection,
we recently develop the common emergent electrogravity model which would like
to present here. This model incorporates the ordinary QED and tensor field
gravity mimicking linearized general relativity. The SLIV is induced by
length-fixing constraints put on the vector and tensor fields, $A_{\mu
}^{2}=\pm M_{A}^{2}$ and $H_{\mu \nu }^{2}=\pm M_{H}^{2}$ ($M_{A}$ and $M_{H}$
are the proposed symmetry breaking scales) which possess the much higher
symmetry then the model Lagrangian itself. As a result, the twelve Goldstone
modes are produced in total and they are collected into the vector and tensor
field multiplets. While photon is always the true vector Goldstone boson,
graviton contain pseudo-Goldstone modes as well. In terms of the appearing zero
modes, theory becomes essentially nonlinear and contains many Lorentz and CPT
violating interaction. However, as argued, they do not contribute in processes
which might lead to the physical Lorentz violation. Nonetheless, how the
emergent electrogravity theory could be observationally differed from
conventional QED and GR theories is also briefly discussed.
