“Is the universe a hologram? Describing the universe requires fewer dimensions than we might think; this may not just be a mathematical trick, but a fundamental feature of space itself”

As reported in this article from TU Wien in Vienna, recent developments in theoretical physics have shown how we may reduce the mathematical description of physical events into analogous models using less dimensions than previously thought.

In a way, 3D models would be re-written as instances of 2D systems.  Our universe complexity may be understood in less dimensions that are dreamt in our minds.
