The foundational idea in String Theory posits that the whole Universe may be nothing but just a Hologram.
The Holographic Principle Suggests that what we experience every day in 3 dimensions, may really just be information on a surface located at the farthest reaches of the cosmos.
The holographic principle was inspired by black hole thermodynamics, which conjectures that the maximal entropy in any region scales with the radius squared, and not cubed as might be expected.
In the case of a black hole, the insight was that the informational content of all the objects that have fallen into the hole might be entirely contained in surface fluctuations of the event horizon.
The holographic principle resolves the black hole information paradox within the framework of string theory.
We all might just be a projection of that information. Encoded in a way to have a sense of each other’s physical existence and able to touch and feel everything around.
The entire Universe might just be a projection.
And the only theory that can help resolve this dilemma and answer every question is “The String Theory“.
Holographic Principle is also a supposed property of Quantum Gravity.
The day we are able to combine General Relativity with Quantum Mechanics, we’ll have the answers to all the questions of the Universe.
