This analysis demonstrates spacetime singularities are properties rather than flaws in general relativity, indicating their role in quantum gravity.
Spacetime singularities are expected to disappear in quantum gravity. Singularity resolution prima facie supports the view that spacetime singularities are mathematical pathologies of gen- eral relativity. However, this conclusion might be premature. Spacetime singularities are more accurately understood as global properties of spacetime, rather than things. Therefore, if space- time emerges in quantum gravity – as it is often claimed – then so may its singular structure. Although this proposal is intriguing, the attempt to uphold that spacetime singularities may be emergent fails. I provide three arguments in support of this claim, drawing upon different views on spacetime emergence.
