Holographic principle states that world is a hologram. Every 3D object has 2D information.As there is lot of matter in the universe,I am thinking how we can describe 3D objects using 2D information,like table, chair, trees, houses, roads etc are 3D objects, how we can describe them using 2D information of 0's and 1's?
And what about standard model particles like higgs boson, photons, electrons, quarks etc , how we can represent them using 2D information of 0's and 1's?
And as in this link(http://www.dummies.com/how-to/content/string-theory-insight-from-the-holographic-princip.html) it talks about for example shadow has all the information about the 3D object(i.e. person). My question is, what's the information? And what is it's format? Is it in the form of 0's and 1's? And how these numbers(0's and 1's) are arranged for different 3D objects and particles?
