  A scenario of galaxy formation is put forward which is a process of sudden
condensation just after recombination. It is essentially based on the fact that
the cosmic matter gas after recombination is a general relativistic Boltzmann
gas which runs within a few $10^6$ years into a state very close to
collision--dominated equilibrium. The mass spectrum of axially symmetric
condensation "drops" extends from the lower limit M about $10^5$ solar masses
to the upper limit M about $10^{12}$ solar masses. The lower limit masses are
spheres whereas the upper limit masses are extremely thin pancakes. These
pancakes contract within a time of about $2.5 \cdot 10^9 y$ to fastly rotating
spiral galaxies with ordinary proportions. In this final state they have a
redshift z about 3. At an earlier time during their contraction they are higly
active and are observed with a redshift z about 5.
