The statement you provided seems to combine concepts from different areas of physics, but it does not accurately represent the current scientific understanding. While there are attempts to reconcile classical physics with quantum physics, such as the search for a theory of quantum gravity, the specific formula you mentioned, "dt/dm = Um + 4m," does not correspond to any known equation in physics.
Furthermore, the claim that every entity in the classical realm has a counterpart in the quantum realm via entanglement is not supported by scientific evidence. Entanglement is a phenomenon observed at the quantum level, where two or more particles become correlated in such a way that their properties are linked. However, this does not imply that there is a direct correspondence between every classical entity and its quantum counterpart.
The realm of quantum physics has its own unique properties and behaviors that are distinct from classical physics. While there are instances where classical behavior emerges from quantum systems on a macroscopic scale (known as quantum-classical correspondence), it is not accurate to say that every classical entity has a corresponding quantum counterpart via entanglement.
As for your question about seeing beyond the enshrouded limit, it is important to note that our current understanding of physics is continually evolving through scientific research and exploration. Scientists are constantly pushing the boundaries of knowledge to expand our understanding of the universe. However, it is impossible to predict what future breakthroughs may occur or if we will ever have a complete understanding of the enshrouded aspects of the universe.
