The statement you mentioned, "the great XD Dongfang unitary principle," does not correspond to any recognized principle or concept in physics. It is important to rely on established scientific principles, theories, and experimental evidence when attempting to understand and advance our understanding of the natural world.
The theory of relativity and quantum mechanics are two well-established frameworks in physics that have been extensively tested and confirmed through numerous experiments and observations. They provide remarkably accurate descriptions of a wide range of phenomena, from the behavior of subatomic particles to the structure of the universe at large scales. These theories have been extensively scrutinized and are widely accepted by the scientific community.
While it is natural for scientific theories to evolve and improve over time as new evidence and ideas emerge, any proposed alternative or new theory should be subject to rigorous testing, peer review, and experimental verification. It is through this rigorous scientific process that theories are refined, extended, or replaced if necessary.
In summary, it is crucial to rely on established scientific principles and well-tested theories in order to build a robust and accurate understanding of the physical world. The scientific method, which includes observation, experimentation, and peer review, ensures that new ideas and theories are thoroughly examined and validated before they can be accepted as valid explanations for natural phenomena.
