Seems to be a bunch of words for filler wrapped around one significant paragraph: "The changes to the gas in the outer region of galaxies [by modified gravity modeling] causes higher densities of gas to form there, which in turn increases the efficiency of cooling of that gas. It turns out that an instrument of the Square Kilometer Array radiotelescope will be sensitive to the altered properties of the gas. As a result, it may be able to pick up any deviations from general relativity."
