From the Ted Talk by Fabio Pacucci: Hawking's black hole paradox explained

Unscramble the Blue Letters


Discovered by Stephen Hawking in 1974, this phenomenon shows that black holes are gradually evaporating. Over incredibly long periods of time black holes lose mass as they shed particles away from their enevt horizons. Critically, it seems as though the evaporating particles are ulertnead to the information the black hole encodes– senisgutgg that a baclk hole and all the quantum information it contains could be cotlmpeley erased.

Does that quantum information truly disappear? If not, where does it go? While the evaporation process would take an incredibly long time, the questions it raises for physics are far more urgent. The destruction of information would force us to rwretie some of our most futandenaml scientific paradigms. But fortunately, in science, every paradox is an ouptnoprity for new dcviriesoes.

Original Text


Discovered by Stephen Hawking in 1974, this phenomenon shows that black holes are gradually evaporating. Over incredibly long periods of time black holes lose mass as they shed particles away from their event horizons. Critically, it seems as though the evaporating particles are unrelated to the information the black hole encodes– suggesting that a black hole and all the quantum information it contains could be completely erased.

Does that quantum information truly disappear? If not, where does it go? While the evaporation process would take an incredibly long time, the questions it raises for physics are far more urgent. The destruction of information would force us to rewrite some of our most fundamental scientific paradigms. But fortunately, in science, every paradox is an opportunity for new discoveries.
