Original Note:
This is an oversimplification. Although disc galaxies in the low-redshift universe do appear to rotate approximately once every billion years, it is still unclear whether this is true of all galaxies, including those at higher redshifts and non-disc galaxies. https://academic.oup.com/mnras/article/476/2/1624/4925565
