Paradox resolved?

In 1992, University of Alberta physics professor Don Page threw a curve into calculations of black hole radiation entropy. Now, almost 30 years later, theories are close to resolving a black hole paradox.

In 1992, University of Alberta physics professor Don Page threw a curve into calculations of black hole radiation entropy. Einstein had thought that no information escaped from a black hole. Hawking calculated that the total amount of entanglement between the black hole and the radiation rises until a black hole dies. But Page theorized that entropy entanglement rises and then reverses in a phenomenon now called the Page Curve. Now, almost 30 years later, theories are close to resolving this black hole paradox.
