In this way we can assert that a massive object generates a spacetime lattice equivalent to a frame reference.\\  It is simple to deduce that lattices of particles of relative motion differ for a Lorentz transformation. Now, combining \eqref{eq:mass} and \eqref{eq:wave}, we have:  \begin{equation}  E^2 = m^2 c^4 + p^ p^2  c^2 \leftrightarrow \omega^2 = \omega_0^2 + k^2 c^2 \end{equation}
