Yes, it&#x27;s true that the most distant galaxies we&#x27;ve observed are only around 13 Gly away, but the fact that number is so close to (speed_of_light * age_of_universe) is just a coincidence. We could, in principle, see light emitted from points in space that are currently 46.5 Gly away, but all such light was emitted long before any galaxies had formed. The OP wasn&#x27;t mentioning that we can see to a maximum distance of ~13 Gly as an unrelated fact with its own cause, it was saying it was because the Universe is ~13 Gy old and that&#x27;s how far light can travel in that time, which isn&#x27;t true.
