Note on the torsion tensor
DOI: 10.1063/1.4809661
Weinberg replies: Sorry, I still don’t get it. Is there any physical principle, such as a principle of invariance, that would require the Christoffel symbol to be accompanied by some specific additional tensor? Or that would forbid it? And if there is such a principle, does it have any other testable consequences?
