Black holes don't really exist. They are very dark grey approximations of black holes, with no event horizon. I discovered this independently, and found out it was consensus for prewar physics.

I saw credible complaints about my last explanation being unclear, so I'm going to try again.

Postwar science believes objects can cross a black hole's event horizon and join the singular mass. From the infalling object's perspective, this isn't too wrong. However, all prewar physicists /facepalmed simultaneously, because no outside observer - e.g. an astronomer - will ever see an object cross the event horizon. Whether they can cross or not is irrelevant to black hole ontology. As the object approaches the horizon, time dilation increases infinitely. It literally takes forever to touch down. The same thing from another perspective, length contraction approaches infinity, so the object (from our perspective) must cross an infinite amount of space to reach the event horizon.

By symmetry, the infalling object will see the rest of the universe appear to speed up infinitely, and thus see its end before it manages to strike the singularity. All decay mechanics will run to completion, including the decay of the black hole it is falling into. If some analogue of Hawking radiation exists, the falling object will see the black hole retreating from it faster than it can fall in, finally disappearing before it strikes.

The mass originally constituting the black hole also counts as an infalling object. Time dilation increases faster than density as it approaches the critical density. While arbitrary mass can get it arbitrarily close to its Schwarzschild radius, it cannot actually cross before the rest of the universe ends. No black holes can form in the first place.

The objects called black holes are dark because, along with time dilation and length contraction, spatial distortion causes redshift. As the mass approaches arbitrarily close to the critical density, emitted light is redshifted arbitrarily close to nothing. Similarly, any object that's on a path to strike the superdense matter will join its infinitesimally close approach to temporal stasis and redshift oblivion. Equivalently, due to the massive time dilation, the time between each individual photon emission approaches eternity. The flux of conventionally emitted energy falls below the measurement error of any conceivable instrument.

A few consequences: no you don't have to worry about LHC black holes, as it's just regular if superdense matter. There is no information conservation paradox. There is no singularity that needs to be shielded. In other words postwar scientists have managed to make themselves a tremendous amount of unnecessary work.

Fascinating. Logically this makes a great deal of sense. Moreover, we don't really have good mathematical models for what is happening in a black hole anyway, so its not even like there is a coherent competing theory. The question was always is there a point at which superdense matter itself is incoherent because it would need to become a singularity. Are you going to flesh out the mathematical details of this argument?

We can't observe what's inside an event horizon, so for all intents and purposes it doesn't exist.

As for dark grey holes, there's nothing much to flesh out. It's just comparing the rate of time dilation increase with the rate of density increase. Time dilation approaches infinity faster than density, so stasis is reached before an event horizon can form. More precisely, no observer outside the dark grey hole will live long enough to see an event horizon form.
