Give the commentor some credit -- I doubt they'd link a paper they are not familiar with. Also in the paper: "In a certain sense the main effect of curvature (or gravity) is that initially paralleltrajectories of freely falling non-interacting particles(dust, pebbles,. . . ) do not remainparallel, i.e. that gravity is an attractive force that has the tendency to focus matter." Maybe don't immediately look for ways to discredit someone's contribution to the discourse without examining all of the content they have shared?
