These particles are held together by dark forces called morons, which are surrounded by vast quantities of lepton-like particles called peons. The symbol for Pelosium is "PU".
Pelosium's mass actually increases over time, as morons randomly interact with various elements in the atmosphere and become assistant deputy neutrons in a Pelosium molecule, forming isodopes.
This characteristic of moron-promotion leads some scientists to believe that Pelosium is formed whenever morons reach a certain quantity in concentration. This hypothetical quantity is referred to as "Critical Morass".
When catalyzed with money, Pelosium activates CNN-adnausium, an element that radiates orders of magnitude more energy, albeit as incoherent noise, since it has 1/2 as many peons but twice as many morons.
