Holographic Principle

The Holographic Principle proposes that our three-dimensional universe may actually be a two-dimensional information structure "projected" onto a cosmological horizon, much like a hologram. This radical theory suggests all physical reality could be encoded at the universe's boundaries, with our perceived 3D world being an emergent phenomenon. First proposed by physicist Gerard 't Hooft and developed by Leonard Susskind, it represents a profound shift in understanding spacetime's fundamental nature. The principle bridges quantum mechanics and general relativity, potentially solving black hole information paradoxes while offering a mathematically elegant framework for a holographic multiverse.
