1. General Covariance

   Linked via "vierbein"

   Teleparallel Gravity (Teleparallelism)
   Teleparallel gravity utilizes the tetrad formalism, where the fundamental object is the vierbein $e^a\mu$, which relates the spacetime metric $g{\mu\nu}$ to the local, flat (Minkowski) metric $\eta{ab}$ via $g{\mu\nu} = e^a\mu e^b\nu \eta_{ab}$. In this framework, General Covariance is preserved by ensuring t…
