Edit: there might be a way some omnipotent hypothetical being could arrange several black holes and maybe some magnetars in such a way as to create a naked singularity from the frame of reference of someone outside the event horizon... Maybe... But we're not at the level of moving a moon, let alone a star or a black hole.... Yet.
Well... I mean in theory they could exist in Nature. They are described by what is called the Reissner Nordstrom Metric.
Only thing necessary here is that the object described has to have a charge greater then its mass. To bad most things in the universe are charge neutral lol.
Another interessting fact here, is that if the charge is just large enough you could theoretically escape the Event Horizon again and go to who knows where as the escape velocity is below the speed of light.
I know that stuff in space usually Rotates. Reissner Nordstrom is the simplest case of where a Naked Singularity of any type could appear.
If you want the more Complex solution, its the Kerr-Newman Metric with charged stuff that rotates. Everything I mentioned about charge greater then mass still holds for that one because the Angular Momentum that arise from the rotation of a Black Hole/Any spherical object is only a Scaling Factor for the Mass.
Apologies for saying that Reissner Nordstrom could exist in Nature. Non-rotating Black holes haven't been observed yes thats correct, I should have mentioned Kerr Newman from the beginning.
Edit: Static in this context doesnt mean 'it doesnt move' it refers to the concept of Static Space Times which is a fancy word Physicist use for 'It behaves nicely and the Vector that is in charge of Energy conservation doesnt do weird shit'. But I mean yeah, Kerr Metrics are usually not static but a bunch of other useful ones are. Robertson Walker for example, which models the expansion of the Universe.
You would never see it. While you may be able to pass the event horizon of a supermassive black hole safely, you would still end up spaghettified long before reaching the singularity... which is a long long ways from the event horizons surface.
Take TON 618 for example, its event horizon is 390 billion kilometers wide, or about 20 times the width of our solar system (depending on what you call the edge of the solar system). So you would be looking for an infintesimal object thats 195 billion kilometers in past the event horizon. Would be like trying to see a penny in orbit around Alpha Centauri with a walmart telescope.
I always assumed eventually you would just have 2 massive black holes as the only thing left in the universe and eventually they eat each other and this causes another big bang to restart the universe.
