Kerr black holes are energetically similar to spinning tops accompanied by frame dragging in the surrounding spacetime. Frame dragging is shown herein to be a universal causal agent for producing multi-messenger emissions. We discuss high energy emissions produced by gravitational spin-orbit coupling along the axis of rotation and low energy emissions from surrounding matter via a torus magnetosphere. Model results point to ultra-high energy cosmic rays (UHECRs) from supermassive black holes at about the Greisen-Zatsepin-Kuzmin (GZK) energy threshold from low-luminosity active galactic nuclei (AGN), and to high-energy photon emissions from stellar mass black holes in ultra-relativistic capillary jets. The former compares favorably with recent results by the Pierre Auger Observatory (PAO). The latter compares favorably with gamma-ray burst data from the High Energy Transient Exporer (HETE) II, \em Swift and the Burst and Transient Source Experiment (BATSE), wherein a finite lifetime of black hole spin is found to improve the correlation between peak energies and true energies in gamma-rays. Matched filtering applied to 600 light curves of long GRBs identifies a process of viscous spin down against matter at the inner most stable circular orbit. We conclude that long GRBs are spin powered, not accretion powered, from core-collapse supernovae and merger events such as GRB060614. Contemporaneous low energy emissions are expected from surrounding matter in gravitational waves by a pressure driven Papaloizou-Pringle instability, and more so than in accompanying MeV-neutrinos and magnetic winds. The latter powers aspherical radio-loud supernovae in collapsars and long duration extragalactic radio bursts from GRB060614 type events. This outlook is of interest to emerging multi-messenger surveys.
