7.2K views · 96 reactions | Is our Universe a hologram? -The holographic universe theory still grips physicists 25 years since it was first published. The reason is that it strikes at the mystery of quantum gravity – the long-sought unification of quantum physics, which governs particles and their interactions, and general relativity, which casts gravity as the product of warped space-time. | The Brain Maze | Facebook

The holographic principle proposed by Gerard 't Hooft and Leonard Susskind in the 1990s, states that the information content of a volume of space can be described by a theory that operates on its boundary, namely its surface. It is primarily applied to black hole physics and string theory. By information, we mean all data necessary to fully specify the state of the system: positions, momenta, and quantum states of all particles within. John Wheeler proposed the concept of "it from bit," where al

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.
