Radiation is everywhere and everything that exists emits and receives it. Radiation is what causes differences and how nothing is 100% the same. Nothing is flawless because of radiation. When you add the elements and space/time with radiation you get an environment advanced enough to support self aware conscious life forms who can exploit the ecosystem to death.
The source of all creation is engulfed in the most potent of radiation. A perpetual being encompassed in pure light.
Looks to me it's more put together as a theory than a fact. An interesting theory in my opinion too. No source required, just more research.
