Black holes encode information on their surfaces, but evaporate away into Hawking radiation. Is that information preserved, and if so, how?
A glowing, abstract representation of a brain, with intricate patterns and lights reminiscent of the innovative spirit behind the Nobel Prize in Physics 2024, set against a dark backdrop.
Artificial intelligence is much more than image generation and smart-sounding chatbots; it's also a Nobel-worthy endeavor rooted in physics!
