In the realm of science, no theory is considered to be absolutely proven beyond any doubt. The same applies to quantum physics. However, quantum physics has been incredibly successful in explaining and predicting the behavior of matter and energy at the atomic and subatomic levels. It has been rigorously tested and verified through numerous experiments and observations.
That being said, scientific theories are always subject to refinement or modification in the face of new evidence or more comprehensive theories. If experimental results were to consistently contradict the predictions of quantum physics, it would indicate that our current understanding is incomplete or flawed in some way.
Scientists constantly strive to test the boundaries of our knowledge and push the limits of existing theories. They conduct experiments and make observations to challenge and expand our understanding of the physical world. If significant contradictions or inconsistencies were to arise, it might prompt the development of new theories or modifications to existing ones.
Nevertheless, it's important to note that quantum physics is currently the most accurate and successful theory we have for describing the behavior of matter and energy at the quantum level. It has been extensively tested and has provided a solid foundation for various technologies and applications, such as quantum computing and quantum cryptography.
