This paper explores a novel hypothesis in quantum mechanics that suggests a combined photon-graviton interaction could provide new insights into the double-slit experiment. Traditional interpretations of the experiment rely on wave-particle duality to explain phenomena like interference and wave function collapse. However, by considering photons (electromagnetic force carriers) and gravitons (hypothetical gravitational force carriers) as interconnected entities within a wave packet, we offer alternative explanations for unresolved issues in wave theory.
