Sean Carroll
It's there. It's sitting there. It's rigid, and I know what it is, and I have some fields vibrating on it. In quantum gravity, space-time itself, is part of the quantum description and it's much harder to know where to start because that's a unique situation. There's no other versions of physics theories in which space-time itself is part of the dynamical playground.
