> and most of those SMBH have relativistic jets with lobes throwing out particles near light speed This is not correct. Most SMBH do not have relativistic jets. The jets only form when the black hole is actively consuming a large quantity of matter. The Milky Way's SMBH Saggitarius A* is not actively eating anything, so it is not producing a jet.
