Maximum Entanglement Speed In Branchial Space

Just as a perturbation in physical space expands at the speed of light, a perturbation in branchial space expands at finite speed, implying a maximum entanglement speed in quantum mechanics (a very rough estimate being 10^5 solar masses per second); if correct, this would manifest as limits on very rapid mergers of large black holes and would mean Bell-inequality correlations, though seemingly instantaneous in physical space, are actually bounded propagation in branchial space.
