Extragalactic cosmic ray Extragalactic cosmic ray Extragalactic cosmic rays are very-high-energy particles that flow into the Solar System from beyond the Milky Way galaxy. The energies these particles possess are in excess of 10 eV. Unlike solar or galactic cosmic rays, little is known about the origins of extragalactic cosmic rays. This is largely due to a lack of statistics: only about 1 extragalactic cosmic ray particle per square meter per year reaches the Earth's surface (see figure). There are many ideas about which processes may be responsible for cosmic rays with such high energies. In the 'bottom-up' approach, cosmic rays gain more
Beyond the Supernatural the game has been ignored in favor of Palladium's more popular series, "Rifts". They cite the years-long development time on "Beyond the Supernatural, Second Edition" (it was mentioned by Kevin Siembieda as far back as January 1998), and the significant delay in producing two necessary supplemental sourcebooks: "Tome Grotesque" (a bestiary) and "Beyond Arcanum" (a book describing magic in the setting). While such things can be brought into the setting from other Palladium game series, due to compatibility with the Megaversal rules, the unique nature of the "Beyond the Supernatural" world makes this unsatisfying to some critics. As such, many
