Quantum Paradox

Information Paradox

The conflict between quantum mechanics and black hole thermodynamics that has revolutionized our understanding of spacetime and information.

GeneralAccessible overview for curious minds

The black hole information paradox is one of the most profound puzzles in modern physics, challenging our understanding of both quantum mechanics and gravity. It arises from a fundamental conflict between two well-established principles of physics.

On one hand, quantum mechanics tells us that information cannot be destroyed - it can be scrambled, transformed, or hidden, but never truly lost. On the other hand, Stephen Hawking showed that black holes evaporate by emitting thermal radiation that appears to carry no information about what fell into the black hole.

This creates a paradox: if a black hole completely evaporates, where does the information about the matter that formed it go? The resolution of this paradox has led to revolutionary insights about the nature of spacetime, quantum entanglement, and the holographic principle.
