The co-moving distance (to where that object was) is 30.444 Gly, but at the time the light was emitted, it was only 3.145 Gly away (=30.444 Gly&#x2F;(1+8.68)).<p><pre><code>  we cannot see past 13Gly because the light has not

We should be able to detect light from Population III stars, i.e., redshifts between z=20 and z=100, so about 13.540-13.704 Gyr in the past (about 0.016-0.180 Gyr since the Big Bang) and at a co-moving distance of about 35.851-42.045 Gly (or distances from us in the past of 0.416-1.707 Gly).<p>Edited to add: For more information, refer to <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Scale_factor_%28cosmology%29" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Scale_factor_%28cosmology%29</a>, specifically the FLRW metric, <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Friedmann%E2%80%93Lema%C3%AEtre%E2%80%93Robertson%E2%80%93Walker_metric" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Friedmann%E2%80%93Lema%C3%AEtr...</a>.
