Yes. All ideas start as irrational until proven. Just because an idea is popular or compelling does not make it true. The claim that particles, atoms, and molecules exist in all possible states at once remains speculative, and currently, there is not enough solid evidence to confirm it.
Yes, experiments like the double-slit experiment hint at it, but hints are not proof. What we actually observe is an interference pattern that suggests particles behave like waves of probability—not direct evidence that they physically exist in multiple places simultaneously.
A key principle of critical thinking is recognizing the difference between observations and interpretations. The observation is clear: quantum systems behave in a way that suggests multiple possibilities exist before measurement. The interpretation that these possibilities are physically real in all states at once is a hypothesis, not a conclusion.
This is where cognitive caution is required. Some interpretations, like Many-Worlds, take the math literally and assume all possibilities actually exist in parallel realities. But interpretations are not reality—they are models we use to describe what we see.
For now, the most rational stance is to acknowledge that quantum mechanics deals with potential states, and until we have clear, repeatable experimental confirmation that all states truly exist at once, the rational position is skepticism. Quantum physics remains an open question—not a settled fact.
