As someone who works in this space, there are numerous misleading depictions about the state of the field. Almost any respectable simulation shows that disk galaxies are widely present at very early times. This is simply an argument of angular momentum conservation and these rotational states are simply more transient at early times compared to the local Universe. &amp;quot;Yan found 87 distant galaxies behind the galaxy cluster SMACS 0723&amp;quot; --&amp;gt; this is not true. They found 87 galaxy candidates. To be fair to the article, they do note that…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/2212.06683/"&gt;Paper and discussion history&lt;/a&gt;.
