If the previous post "What If The Particles Are Photons?" dated 12 Dec 2017 is true, then the hidden truth is that entangled particles in a volume of,
\(V_D=\cfrac{4}{3}\pi(2c)^3\)
is manifested as one particle in the orthogonal time dimension.
Why is this so? If time and space are a conjugate pair of the Fourier transform, we may visual this as a single signal source in the time domain being transformed to points in a volume, \(V_D\), in the space dimension.
No need for collisions in the time dimension for entanglement. They are one particle. There may still be the need for transients.
Maybe...
Note: \(P=energy\,per\,unit\,volume=\psi\)
