Here is the abstract of the talk:
I analyse the status of spacetime singularities in light of singularity resolution in quantum gravity (QG). The avoidance of singularities in QG appears to make a strong case for the view that spacetime singularities are
nothing more than mathematical pathologies of general relativity. However, this conclusion may be too hasty. Spacetime singularities are more accurately understood as global properties of spacetime rather than things. Talks about singularities are replaced
by talks about singular spacetimes in rigorous definitions. Therefore, if spacetime emerges in QG -- as it is often claimed -- then so may its singular structure. Although this proposal is intriguing, I argue that the attempt to (re)instate singularities in
QG through spacetime emergence fails.
