Does any of our quantum gravity theories like String Theory or Loop Quantum Gravity (what else?) answer "why" mass/stress/energy curve Spacetime? Or do they just describe it a priori?(adsbygoogle = window.adsbygoogle || []).push({});

Note I'm not asking why mass/stress/energy curve Spacetime. I just want to know if there is a Quantum Gravity theory that describe why. Thanks.
