This paper presents a mathematical derivation of the unified field equation by reducing it to a common denominator to extract the product of effective masses M1M2. This process naturally reveals an interaction term (mq term) where gravity and electromagnetism merge. Furthermore, we demonstrate that while this equation maintains geometric symmetry in the “equilibrium state” (F = 0), aligning with classical conservation laws (action-reaction and momentum conservation), this symmetry breaks down in the “non-equilibrium state” (F ̸= 0). This suggests a mathematical basis for systems to obtain spontaneous thrust through geometric configurations of spacetime.
