Regarding Virtual Particle Theory and how one particle can become a pair of virtual particles which quickly rejoin into the original particle as if they had never been there.
This process is similar to how an ellipse, such as a circle with equation x2+y2=1, can be rotated along the imaginary axis by y=yi, with the result being a hyperbola of x2-y2=1, hence a single observable object becomes a pair of observable objects. We then continue the rotation of y=yi and the hyberbola returns to a circle.
I therefore propose that matter spins along a virtual axis revealing a pair of entangled virtual particles, which represents the 4th dimensional profile of matter. Continuation of the spin along this virtual axis reveals the original profile of matter again.
