Digital Dreams

I once told myself if the world I experience ever proves to be impossible I will have to assume it is all a dream.

Given the digital nature of Quantum Mechanics and apparent impossibility of real physical worlds, we may be living in a giant digital dream or something equally unlikely.

Undecided Quantum States

Firstly the incompleteness of the universe seen in mixed quantum states. Bell's statistical analysis showed that methods and timing of observations do in fact statistically influence outcomes of entwined objects in mixed states, with 50% of outcomes supposedly impossible under classical probability.

This (along with observations apparent ability to turn waves into matter streams) suggests mixed states are in fact undecided rather than unknown.

Fictional Worlds & Time

Reverse Causation and reverse time flows and unwritten aspects of the past are not things we expect of our "real" everyday world. They are however all possible and even necessary in Quantum Mechanics. relative spacetime models where past and  present are all mixed up.

Such craziness with time is usually only seen in works of fiction. In a work of fiction you can introduce a character and decide later where he was born or make up a rich uncle who dies leaving him a fortune if the plot needs it. You can even have characters go back in time.  If you write yourself into an impossible situation you can rewrite the chapter again or edit your opening scene that caused the clash.

If such things happened in our world we might assume we were living in a made-up fantasy rather than reality.

Theses things however supposedly happen all the time mostly at the quantum (Plank) level beyond our everyday notice but any impossible events make us wonder whether our world is real.

Simulation Model of Physics.

Cybernetics & Information Physics

Cybernetics was developed (before computers?) as a way of comparing models from different branches of science by describing processes as information exchanges. Today we translate almost everything into digital information for computers to process but at the time it was a novel idea. Cybernetics was used as a way of comparing things from totally different areas of knowledge. E.g. Cybernetic comparisons of information processing complexities of nuclear fusion in stars and the cognition in brains suggests Einstein may not have been as clever as our sun Sol.

Today Information Physics and Quantum information Theory have been so successful in modelling "real world physics" that it appears that our world is more like a digital simulation that a "real" or "analogue" world.

Quantum Bits and Holographic Theory

"Plato Cave" compares our perceived world to shadows on a cave wall from a flickering lamp shining through dirty cracked glass. The real  world he believed was far more complex and had more dimensions than what we see.

Einstein's GR Spacetime and Wittens 10D membrane multiverse fit this description.

Holographic Theory on the other hand suggest an even simpler shadow may be the real world and we might be living in a 2D world seen as if through 3D glasses, or we might be living in a data stream of quantum bits as suggested by Quantum Information Theory.

The point of Holographic Theory is all these levels of shadow or projection are mathematically equally valid.
