Nevertheless, galaxies with highly peculiar morphological properties were found by us during our searches, and will be investigated in detail in the years to come.
When we turn from galaxies to the distribution of galaxies, the distribution does not seem to exhibit design - it looks rather random and haphazard.
On the outside of galaxies there is much less light, meaning that there is much less mass concentrated in these regions.
The interactions of galaxies will also lead to large changes of angular momentum and energy.
Research on barred galaxies has been performed using observations, theory and numerical simulations.
We have never observed galaxies in the process of controlled disintegration.
Following the introductory chapter, the next section reviews the current state of cosmology and prevalent theories of how matter, stars, galaxies and the universe formed.
I have distinguished three sorts of galaxies, but it remains an open question which of the three types are instantiated.
