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.
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.
