holographic principles

The holographic principle suggests that all the information about a three-dimensional space can be encoded on its two-dimensional boundary, similar to a hologram where a 3D image is stored on a flat surface. In physics, this implies our universe might be described by information stored on a distant, lower-dimensional boundary. It helps reconcile how gravity and quantum mechanics coexist and hints that the universe’s true nature may be fundamentally holographic, with the familiar 3D world emerging from more fundamental, surface-based information.
