Has anyone read something related? Thanks to point me to such papers, and to express your ideas or knowledge. The Mach principle aknowledges that a "frame of inertia" can only be conceived with respect to the whole bulk of nearby universe. That is to say that physics frame of reference is defined by matter interacting on a large scale through gravity. This is -of course- fully integrated in GR. I ask myself if quantum entanglement could not be limited by these very weak, long-range, but nevertheless determining interaction.
