I want to paraphrase this sentence into something smaller - "Laypersons cannot understand findings from papers in this field, no matter how much time they spend. To understand them, experts are required and the process may require sizeable resources and time"
I thought of something like "Findings from these papers are resource-intensive and temporally incomprehensible to laypersons." but I know it's wrong. What kind of phrase can I use to describe the nature of the process of "understanding findings from papers"?
