First read this – Wave or Particle or Neither?

If indeed, a particle is a PROCESS (one in which several pulses combine to appear at a point and then dissolve away…), then this provides at least a starting point to understand entanglement of two distant particles.

They were never particles in the first place. They were pulses (essentially superposition of several waves), that were ALWAYS entangled, in the way that two threads would tie around each other. Unless explicitly UNWRAPPED, the threads would stay entangled. A simple separation of the two threads, WITHOUT unfolding the entangled portions, would accomplish nothing.
