This brief and simplified discernment is to suggest exploration process and mechanism of intertwinement and entanglement in nature:
The process of intertwinement and entanglement have been illustrated in this recent discernment https://www.epistemologyontologyfoundationinstitute.org/philosophy-and-science-beyond-the-macro-world/may-07th-2019. And which implied that the essence of nature are in and nature spectra-field permeates everything. In other words, there are immaterial or unobservable (or undetectable as has suggested in past discernment) nature essence and spectra-field that are the basis of unified matrix spectra-field as part of nature underlying wholeness process and mechanism as had suggested in past discernment (as in the case of dark matter and energy). And therefore, interaction polarization can cause entanglement not only at the observable or detectable spectra field but also at the underlying nature process and mechanism spectra-field.
For example, when polarization entanglement tests between element particles on earth and with cosmic entities many billions years away, since the subtle or hidden underlying spectra-field interconnectivity for potential intertwinement and entanglement is already set-up or existed, the polarization or interaction that trigger entanglement would actually result in observation between entangled elements distance on earth by the detectors rather than cosmic entities many billions (or even further beyond that are within reach of instruments) light years away (i.e. observable cosmic entities spectra-field are also intertwined and entangled with immaterial or unobservable spectra-field. In addition, even if equipment and apparatus are indoor and shielded, the immaterial or underlying spectra-field still permeates them). This is not to say that the speed of light cannot be exceed (i.e. depending on the types of intertwinement and entanglement) Rather, to state that there are immaterial spectra-field as part of nature underlying unified wholeness process and mechanism since this would be far more dynamic, transformative, practical, robust, and efficient way of wholeness intertwined and entangled mechanism between realms and worlds (in other or simple words, entanglement between entities, in particularly elements particles billions light years away and beyond would not be possible due to many cosmic interactions and causalities along the path). And this can be verified through entanglement of particles with cosmic entities at different entanglement distances on earth or in earth orbit.
And therefore, the subtle or hidden parameters or variables are nature immaterial essence and spectra-field. And which can be derived from the universal process of "Dependent and Interdependent Origination" and Dependent and Interdependent Arising" as had discerned in diverse ways in the pasts.
