The Holographic Principle: How Gravity Might Reduce 3D Reality to 2D Data
The holographic principle suggests that all information within a volume of space can be encoded on its boundary surface. While initially derived from black hole entropy calculations by Jacob Bekenstein and Stephen Hawking, the concept was solidified by the AdS/CFT correspondence in the late 1990s. This mathematical equivalence between gravity in a curved space and quantum mechanics on its boundary implies that our three-dimensional reality might be an emergent projection of lower-dimensional quantum data, challenging traditional views of space and time.
