The Principle of Certainty
It is possible to prove the principle of certainty in a different way from the theory of relativity, de Broglie particle wave duality, the principle of uncertainty. The principle of certainty is the formula for measuring the position and momentum of a particle at the same time. If the theory of relativity, the principle of uncertainty is correct, then the principle of certainty must be considered correct. Because it is possible to prove the principle of certainty from the principle of uncertainty, it is also possible to prove the principle of certainty from the theory of special relativity. Again the idea of the principle of certainty comes from the de Broglie particle wave duality principle. Max Planck's radiation formula can be proved from the principle of certainty.
