A Love Song With My Partner, a Cold Entanglement

We don't have a pontil theory of gravity. We do oint of mechanics. It's the reason why all your mobile phones work. The two fundamentally disagree on the nature of space time. Around the event horizon of a black hole, we have quanti mechanical effects to the happening as well as gravity. They have to coincide there. So this becomes a very good place to look for quantum theory of gravity - how gravity works at quantum scales.
