==Cosmic censorship hypothesis== {{Main|Cosmic censorship hypothesis}} The cosmic censorship hypothesis says that every gravitational singularity will remain hidden by its event horizon. [[LIGO]] events, including [[GW150914]], are consistent with these predictions. Although data anomalies would have resulted in the case of a singularity, the nature of those anomalies remains unknown.<ref>{{Cite journal|last=Pretorius|first=Frans|date=2016-05-31|title=Viewpoint: Relativity Gets Thorough Vetting from LIGO|url=https://physics.aps.org/articles/v9/52|journal=Physics|language=en|volume=9|page=52 |doi=10.1103/Physics.9.52|doi-access=free}}</ref> Some research has suggested that if loop quantum gravity is correct, then naked singularities could exist in nature,<ref>M.
