1915: Einsteinâs first explicit equation for General Relativity was mathematically wrong; it set a divergence free 2-tensor equal to a non-divergence free 2-tensor. But it wasnât fundamentally wrong. It needed a small fix reversing the trace component.  | 1915: [[Albert Einstein|Einsteinâs]] first explicit equation for [[General Relativity]] was mathematically wrong; it set a divergence free 2-tensor equal to a non-divergence free 2-tensor. But it wasnât fundamentally wrong.

In the 1920s E. Schrödingerâs theory didnât agree with experiment. Why? Because the spin wasnât properly incorporated. It wasnât fundamentally wrong, and was patched. Same theory. | In the 1920s E.

In 1928, P. Diracâs Quantum Field Theory gave nonsense answers? Why? A small goof conflating bare and dressed masses. Harder to fixâŠbut in no way a fundamental error. The theory of Quantum Electrodynamics or QED still stands.  | In 1928, [[Paul Dirac|P. Diracâs]] [[Quantum Field Theory]] gave nonsense answers? Why? A small goof conflating bare and dressed masses.

But the truth is anyone can see the incompatibility between gravity and gauge theory if they are not being told that gravity is a special kind of [[Gauge Theory|gauge theory]]. Which it absolutely is not as formulated by Grossman, Einstein and Hilbert. | But the truth is anyone can see the incompatibility between gravity and [[Gauge Theory|gauge theory]] if they are not being told that gravity is a special kind of [[Gauge Theory|gauge theory]].

[[Morals|Moral]]: The problem holding us back from a Theory of everything is **Classical**, and not Quantum. The quantum comes as desert after classical compatibility. Itâs not the main issue. A red hearing that throws us off following the scent. Itâs a distraction that should have fooled almost no one who was thinking for his or her self. | [[Morals|Moral]]: The problem holding us back from a Theory of everything is **Classical**, and not Quantum.
