  We outline two concepts to explain Ultra High Energy Cosmic Rays (UHECRs),
one based on radio galaxies and their relativistic jets and terminal hot spots,
and one based on relativistic Super-Novae (SNe) or Gamma Ray Bursts (GRBs) in
starburst galaxies, one matching the arrival direction data in the South (the
radio galaxy Cen A) and one in the North (the starburst galaxy M82). Ubiquitous
neutrino emission follows accompanied by compact TeV photon emission,
detectable more easily if the direction is towards Earth. The ejection of
UHECRs is last. We have observed particles up to ZeV, neutrinos up to PeV,
photons up to TeV, 30 - 300 Hz GW events, and hope to detect soon of order Hz
to mHz GW events. Energy turnover in single low frequency GW events may be of
order 10^63 erg. How can we further test these concepts? First of all by
associating individual UHECR events, or directional groups of events, with
chemical composition in both the Telescope Array (TA) Coll. and the Auger Coll.
data. Second by identifying more TeV to PeV neutrinos with recent SMBH mergers.
Third by detecting the order < mHz GW events of SMBH binaries, and identifying
the galaxies host to the stellar BH mergers and their GW events in the range up
to 300 Hz. Fourth by finally detecting the formation of the first generation of
SMBHs and their mergers, surely a spectacular discovery.
