Description
Black holes tell us that, at the Planck scale, information in spacetime should be coarse-grained.
Carefully studying the foundations of quantum mechanics, one also hits upon coarse grained
structures, but they are classical. Quantum behavior automatically comes about when taking
the continuum limit. This suggests that the logic applied in CDT should also be classical logic.
This may remove some of the quantum mysteriousness of General Relativity, but of course it
raises other questions, of which some will be addressed.
