Destructive interference of electromagnetic (EM) waves does not create negative energy; instead, energy is redistributed to areas of constructive interference, maintaining a non-negative energy density. The lowest energy density for EM waves is zero, and while destructive interference approaches this value, it does not imply the existence of negative energy. Experimental verification of energy conservation in EM waves is robust, although the precision of measurements can vary. Discussions about potential negative energy associated with destructive interference often lack empirical support and can lead to speculation without scientific basis. Overall, the consensus is that while theoretical discussions on negative energy exist, they do not hold significant implications for established physics.
