Abstract: Essentially GUT and Vacuum Field are related to Quantum field where Quantum entanglement takes place. Mass energy equivalence and its relationship with Quantum Computing are discussed in various papers by the author. Here we finalize a paper on the relationship of GUT on one hand and space-time, mass-energy, Quantum Gravity and Vacuum field with Quantum Field. In fact, noise, discordant notes also are all related to subjective theory of Quantum Mechanics which is related to Quantum Entanglement and Quantum computing.
