Consider the general case in which an effective spacetime emerges in a theory of QG. a situation in which 'during' the big bang time does not emerge from the fundamental 11Note the difference from string cosmology, in which both spacetime regions have a finite scale factor a ./cache/work_nibqabtk2vb6xkfouwlja3n5sa.pdf ./txt/work_nibqabtk2vb6xkfouwlja3n5sa.txt
