- operator to get the Einstein tensor capital G mu nu from the Riemann tensor. That thing, there's two branches, right? There's a branch that uses the star operator to do this little trick, which is called the Chern-Simons branch. And then there's the Einstein contraction. And both of those results in Euler-Lagrange equations with the curvature tensor with a contraction, um, that gets you from two forms to one forms. That's how, you know, you're in GU because you're— Geometric Unity: Unifying All Forces + Generations | Eric Weinstein
