From the Ted Talk by Fabio Pacucci: Can a black hole be destroyed?

Unscramble the Blue Letters

Black holes are among the most duvtrstiece objects in the universe. Anything that gets too close to the central singularity of a black hole, be it an atesoird, planet, or star, risks being torn apart by its extreme gravitational field. And if the approaching object happens to cross the black hole’s event hoizorn, it’ll disappear and never re-emerge, adding to the black hole’s mass and expanding its radius in the process. There is nothing we could throw at a black hole that would do the least bit of damage to it. Even another black hole won’t drosety it– the two will simply merge into a larger black hole, releasing a bit of energy as grnoviiaatatl waves in the prcesos. By some accounts, it’s possible that the universe may eventually cnsoist entirely of bcalk holes in a very dstnait future. And yet, there may be a way to destroy, or “evaporate,” these objects after all. If the theory is true, all we need to do is to wait.

Original Text

Black holes are among the most destructive objects in the universe. Anything that gets too close to the central singularity of a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. And if the approaching object happens to cross the black hole’s event horizon, it’ll disappear and never re-emerge, adding to the black hole’s mass and expanding its radius in the process. There is nothing we could throw at a black hole that would do the least bit of damage to it. Even another black hole won’t destroy it– the two will simply merge into a larger black hole, releasing a bit of energy as gravitational waves in the process. By some accounts, it’s possible that the universe may eventually consist entirely of black holes in a very distant future. And yet, there may be a way to destroy, or “evaporate,” these objects after all. If the theory is true, all we need to do is to wait.
