 Even without an accepted, strict definition of singularity for relativistic spacetimes, the question can be posed: what would it mean to ascribe existence to singular structure under any of the available open possibilities? It is not far-fetched to think that answers to this question may bear on the larger question of the existence of spacetime points in general (Curiel 1999, 2016; Lam 2007). (See the entries  The Hole Argument  and  Absolute and Relational Theories of Space and Motion  for discussions of the question of the existence of spacetime itself.)
