I understand the last three (universal topology, a plot of timelike vs spacelike dimensions and kind of universal structure they result in; size and density limits on objects of conventional matter plotted in part against age wrt that of the universe itself {something something, cosmic inflation imposing its own size limits the further you go back in time}; and planetary composition vis a vis mass, size and temperature respectively), but that first one I understand only just enough to wonder just what in the absolute fuck 'Classified' is supposed to be
"We know it exists and what it is, we want you to know that we know it exists and what it is. What is it? We ain't tellin'. Don't think about it too hard, give us more money."
