This Quantum Magnetic Force theory completes our understanding of all the laws of physics in the universe. It explains dark matter and dark energy, while uniting all the forces in the universe by recognizing that the force we call gravity has its source in the quantum physics world. This Quantum Magnetic Force theory provides the correct understanding of the laws of physics by explaining how the force, which is call gravity, is generated. The Quantum Magnetic Force is actually the force we believe to be gravity. This theory features an equation that calculates the Quantum Magnetic Force and, based on this theory, the author proposes a new design for a fusion reactor.
