>* Physics has been stuck in a quagmire for 50+ years. The "foundational research" hasn't moved, possibly since Einstein (who only became an academic after publishing his important work).*
You forgot all Quantum Mechanics. His only collaboration was the explanation photoelectric effect. (He got a Nobel price for this but is it a very tiny part of Quantum mechanics.)
The electroweak unification and quantum chromodynamics were discovered after Einstein's death. Also the Higgs boson prediction and experiments are post Einstein's death.
