Different Approaches to the Fundamentals of General Relativity

Ali Riza Sahin

While efforts to find solutions to the famous problems of general relativity theory continue, we ask three new fundamental questions that can be considered in addition to these problems without getting lost in the depths of general relativity theory. These questions involve the principle of equivalence (the most basic principle of the theory), the boundary condition between general relativity and Newtonian gravity, and the Schwarzschild metric, which is accepted as the simplest solution in general relativity theory. When we try to address these questions, we see that the answers contradict the foundations of general relativity.
