It's been a long time since I posted here, but I've read on the forum from time to time. And I have a curiosity and some questions about these objects, namely the naked singularities. From what I understand, a naked singularity is a singularity without an event horizon, so they are visible. Questions: 1. Are they real, or their existence is just theoretical? 2. How can they be visible if the gravity in their vicinity is so strong? 3. A black hole may lose its own event horizon, in certain conditions, thus becoming a naked singularity? 4. If the naked singularities do exist, what would be the consequences on the current understanding of universe? Thanks for any insights.
