The Elusive Quest for Unified Physics: Beyond Einstein's Reach

The challenge of unifying electromagnetism with gravity lies in the probabilistic nature of quantum mechanics. Richard Feynman's path integral formalism requires considering every possible path and interaction a subatomic particle can take, resulting in complex calculations. However, when gravity is included, the number of infinities becomes overwhelming, and current techniques fall short. The inability to reconcile gravity with quantum mechanics stems from the multitude of infinities and the complexities of spacetime bending during interactions, posing a significant challenge for physicists.
