Mach effect

The Mach effect refers to a phenomenon in physics where mass can seemingly be affected by accelerating energy or objects nearby, due to interactions predicted by Einstein’s theory of relativity. Essentially, it suggests that the inertia of an object—its resistance to acceleration—may be influenced by the distribution and motion of mass and energy in the universe. This idea implies a connection between local physical behavior and the overall universe’s structure, hinting that mass and inertia are not entirely intrinsic but can be affected by the environment, potentially opening paths for advanced propulsion or energy research.
