Ten Times More Galaxies

So if the number of galaxies were undercounted by a factor of ten, does that do anything to explain the "missing mass" that dark matter/dark energy are supposed account for?

Update (October 26):  Not a related study, but a paper published in Scientific Reports by lead author Subir Sarkar from Oxford University uses a larger database of supernovae to dispute a previous claim that the expansion of the universe is accelerating. It's been the justification for the hypothesized dark matter/dark energy.

[W]e find, rather surprisingly, that the data are still quite consistent with a constant rate of expansion.

Update (May 28, 2020):  It's cool how J. Xavier Prochaska and Jean-Pierre Macquart describe their efforts to find missing "baryonic" matter in the form of low-density, hot plasma dispersed throughout the universe. The missing matter is half of the predicted 5% of all matter represented by baryons. The other 95%, of course, is dark matter/dark energy whatever the hell that is.
