We elaborate on the idea of fake particle and study its physical consequences. When a theory contains fakeons, true classical limit is determined by quantization subsequent process "classicization". One major predictions due to particles violation microcausality, which survives limit. This fact gives hope detect experimentally. A fakeon spin 2, together with scalar field, able make quantum gravity renormalizable while preserving unitarity. claim that emerging from this construction right one. By means classicization, we work out corrections field equations general relativity. show finalized have, in simple terms, form $\langle F\rangle =ma$, where $ an average includes little bit "future".
