要旨

We argue for enlarging the traditional view of quantum gravity, based on
"quantizing GR", to include explicitly the non-spatiotemporal nature of the
fundamental building blocks suggested by several modern quantum gravity
approaches (and some semi-classical arguments), and to focus more on the issue
of the emergence of continuum spacetime and geometry from their collective
dynamics. We also discuss some recent developments in quantum gravity research,
aiming at realising these ideas, in the context of group field theory, random
tensor models, simplicial quantum gravity, loop quantum gravity, spin foam
models.
