Physicists Say Holographic Principle Unifies Gravity and Quantum Mechanics
Theoretical physicists have developed the AdS/CFT correspondence, a mathematical framework showing that a gravitational theory in a given volume of space is equivalent to a quantum theory operating on its boundary surface. The idea, now known broadly as the holographic principle, implies that the amount of information in a region depends on its surface area rather than its volume, and it underlies a widely accepted resolution to the black hole information paradox that Stephen Hawking raised.
