"Inverse nanobarns"? WTF? I've never heard of the unit "barn", but a nanobarn just sounds like its about to spew out nanounicorns followed by nanoblackholes.
But its cool to see their progress and how they're slowly ramping up the power and beams to split instead of just going full throttle all at once.
The "barn" unit is quite useful in everyday life. For instance a barn megaparsec is a convenient measure of volume of powdered sugar, since 1 barn megaparsec of powdered sugar has 10 calories.
