Contrary to popular belief, the physical entanglement properties of a classical physical system are the same as those of a quantum system.
However, we assume that:
1-The entanglement that exists in classical and quantum physics systems is the entanglement between the energy density at the different free nodes of the system and the internal walls.
2- The entanglement energy is transmitted from the walls to the free nodes and vice versa at the speed of information which is the speed of light c.
3-The most important property of entanglement is that its center coincides with the center of mass CM called the middle point of the system.
NB: Items 1,2,3 come strictly from the statistical theory of matrix chains B [1].
