Once Julian provided context on all of the esoteric science that the research logs referenced, Rui had a far easier time understanding all of it. But he mostly focused on the Flux Evolution method, as it had been renamed by the end of the research logs.
"I see." Rui murmured as he read through the elaborate explanation report that Julian provided him. "The reason that the evolution procedure cannot just be performed infinitely is that there is a time limit before the radiation administered becomes lethal due to overdosage. On Earth, this would be considered to be an Acute Radiation Syndrome."
Julian's report mentioned prolonged exposure to radiation was lethal. What he was surprised by was the fact that they didn't know why. Both Julian and the researchers treated radiation as a dangerous but largely unknown and inscrutable form of energy similar to that of light.
