The &amp;quot;problem observations&amp;quot; both of them try to address are what appear to be huge galaxies at an early time (according to redshift) when there shouldn&amp;#x27;t have been such large galaxies yet.  The aforementioned paper says maybe the Universe is actually much older.  This paper says maybe those huge early galaxies aren&amp;#x27;t actually galaxies but &amp;quot;Dark Stars&amp;quot; instead.</text></comment>
