Query: The Nature is Simple in Essence - Blueprint for Unification of Gravity
  and Electromagnetism   The Temporal Fluctuation Model proposed in present paper represents an
attempt for a unitary vision for gravity, inertia and electromagnetism. We
obtain the main results of General Relativity and Electromagnetism and the
theory, until now, don't contain self-contradictions. As well, we obtain the
"unified potential" which has terms that coupling gravitation with
electromagnetism and who could be the basis for future technological
applications.
