This idea is evoked most significantly in a vital law of physics: the total anmout of quantum information in the Universe must be conserved. Even if you destroy an object beyond recognition, its quantum information is never permanently deeteld. And thtrleaiceloy, knowledge of that information would allow us to rertecae the object from its particle ctoonepmns. Conservation of information isn’t just an arbitrary rule, but a mathematical necessity, upon which much of modern secince is built. But around black holes, those foundations get shaken.

Original Text

This idea is evoked most significantly in a vital law of physics: the total amount of quantum information in the Universe must be conserved. Even if you destroy an object beyond recognition, its quantum information is never permanently deleted. And theoretically, knowledge of that information would allow us to recreate the object from its particle components. Conservation of information isn’t just an arbitrary rule, but a mathematical necessity, upon which much of modern science is built. But around black holes, those foundations get shaken.
