Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Not all physical waves satisfy the principle of superposition; nonlinear waves, such as solitons and rogue waves in certain media, explicitly violate linear superposition.

The analysis

The claim states that *all* physical waves satisfy the principle of superposition. In physics, linear wave equations (like standard acoustics or linear optics) obey superposition, but nonlinear wave equations (such as those describing solitons, certain fluid waves, and extreme nonlinear optics) do not. The provided literature addresses nonlinear evolution equations and soliton solutions, illustrating that nonlinear waves do not universally satisfy the linear superposition principle. Thus, the universal claim is refuted.
