In the context of loop quantum cosmology or loop quantum gravity in general, some wider issues arise that have already been touched upon briefly. This has to be seen in the general context of what one should expect from quantum theories of gravity, for which there are several quite different approaches. These issues deal with questions of the uniqueness of theories or solutions and what information is accessible in one universe. Also the role of time plays a more general role, and the related question of unitarity or determinism.
