What Are Black Holes and Their Connection to Quantum Mechanics?

TL;DR

Black holes are regions in space where gravity is so strong that nothing, not even light, can escape. They challenge fundamental principles of quantum mechanics, particularly in relation to the conservation of information, leading to ongoing debates in theoretical physics. Recent discussions explore the holographic principle, which suggests that information about objects falling into black holes may be encoded on the event horizon.
