Tension mounts, indeed!

This indicates that galaxy formation is not completely understood. If
it were, of course, no-one would work on it.

Remember, galaxy formation is not computed/simulated from first
principles, but models and algorithms are developed in association with
observations. (This does not mean, though, that they have no predictive
power.) So, we can learn something from new observations! Great!

In as much as there appears to be less mass
than required by law of Mass Action for observed galactic formation,
perhaps one should look at the actual mass formation mechanism at BBN.
The Star Collaboration is finding new particle formation mechanisms
in the plasma gluon plasma.
