Are there new hermitian operators in quantum gravity?
Background: In many worlds interpretation (MWI). We have the preferred basis problem and the basis are for example position, momentum, spin. Each of those bases come from a hermitian operator: they are the eigenbasis of the (for example) position operator.
In quantum gravity, could a new bases exist? What theory and which model has it?
