TPF : Why is there something?

Quantum gravity hasn't been figured out yet, but isn't it then a wonder then how QM works so well? — PoeticUniverse

I'm just guessing. But perhaps the Quantum Gravity gap is simply a matter of scale. Quantum effects typically manifest only on the smallest scales. And gravity is so weak that its effects only become apparent on cosmic scales, such as the curvature of vast quantities of space. Gravity is general and diffuse, while sub-atomic forces are specific and focused. Particle colliders require massive energy inputs just to study local quantum scales, but that's trivial compared to the gravitational forces of non-local Black Holes. Apparently, we need to amp-up our instruments in order to study Quantum effects inside a ginormous gravity well. Could the QG mystery be that simple, and that monumental?

Black Hole :
You might expect the authors to celebrate, but they say they also feel let down. Had the calculation involved deep features of quantum gravity rather than a light dusting, it might have been even harder to pull off, but once that was accomplished, it would have illuminated those depths. . . . .
In some way or other, space-time itself seems to fall apart at a black hole, implying that space-time is not the root level of reality, but an emergent structure from something deeper. Although Einstein conceived of gravity as the geometry of space-time, his theory also entails the dissolution of space-time, which is ultimately why information can escape its gravitational prison.
