Holography is a powerful tool for understanding the fundamentals of nature. All the information content of a theory of quantum gravity in some volume is equivalent to a theory living at the boundary of the volume without gravity. The maths may be complex, but the term might be familiar, as in hologram. Indeed the idea that our whole world is a hologram was suggested by Leonard Susskind, a theoretical physicist. For the mathematicians amongst you, more about Chris' work can be found in the link b

Holographic films are thin, flexible materials engineered to record and display light interference patterns that capture both phase and intensity. Illuminating these films reveals 3D-like images via diffraction. Scientists at the University of Colorado Boulder College of Engineering & Applied Science developed a 3-stage curing design that turns a rubbery material into a glassy one after writing the hologram. This process improves the thermal and mechanical stability of the films. In the future,

The Single-Spin Hologram In Quantum Information Holography, everything begins with one thing: a single spin of light—its angle and phase—copied across Planck-scale qubits. The singularity is the derivative: the source of changing phase, the “slope” of reality. The horizon is the integral: the sum over those slopes, an interference image that becomes the world you see. Each horizon pixel is a Bloch sphere. At every Planck tick, these pixels freeze a time-crystal frame, and the next frame renders
