Singularities {naked singularity} can have high density but not enough gravity to form event horizons. Space-time paths that go through time can enter and leave naked singularities (but cannot leave other singularities). For example, spindle-shaped singularities have spindle ends that are naked singularities. Objects with spin faster than mass-determined rate are naked singularities. Objects with electric charge higher than mass-determined rate are naked singularities.
