Regardless of the poetic 'outer edges' is it possible what might be meant is in the context of a hyperspherical universe where the radius is time and is 13.5 by?  The center being when the big bang occurred.  Then the furthest object would be diametrically opposite and hypercircumferentially at 13.5*pi bly or 42.4 bly away?  So in the 'now' being at 30bly away is chicken feed.

Where is "the outer edge of the Universe" and what sort of observation would locate something there?  All that the original report in Nature established was redshift (7.51), age (700 Myr after the Big Bang), and a surprising rate of star formation (330 solar masses / year).
