The Subaru Deep Field, the SDSS:DR14Q Quasar database, and
the Hubble Ultra Deep Field reveal that the universe is a 3-sphere:
matches that of the SDF and SDSS:DR14Q
Dark matter is an error-based excogitation.
is an absolutely wrong expectation.
Observed galaxy rotation perfectly matches the correct math:

Henk Reints MSc. (1957) is a Dutch graduated physicist (Eindhoven University of Technology, 1984).
After graduation he rolled into a job in automation, where he stayed.
But blood is thicker than water, and a few years ago he set himself the goal of understanding the universe
conform Sir Isaac Newton's phrase: hypotheſes non fingo, which he interprets as: I do not excogitate fabrications.
At http://henk-reints.nl/UQ you will find documents of his consistent view on the universe,
derived from observed phenomena (e.g. the HUDF, SDF, SDSS:DR14Q catalogs) without fabricating anything.
Among other topics, it addresses the geometry of the universe, which according to these observed phenomena cannot be anything else than a 3-sphere,
as well as the concept of exotic dark matter, which arises from the completely incorrect expectation of Keplerian decline.
To his opinion, standard cosmology has quite some flaws that originate from assumptions that were not derived from observed phenomena.
