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. Quasars are widely believed to be the cores of young galaxies. Such a regime may hold at the centre of galaxies or close to collapsed stars. Perhaps the strongest form of evidence for the existence of dark matter is the rotation curves of galaxies. There must have been something there to contribute to the gravity needed to keep the stars and galaxies gravitationally bound to their system. Such a large axion density would be incompatible with the formation of galaxies and so is anthropically disallowed. We read how the galaxies are grouped in clusters. The possibility of this happening is about as likely as humans walking the surface of planets of distant galaxies. Change was a given, inducing gradients, forming systems and evolving structures, and the results, emergent over billions of years, included galaxies, stars, planets and life. Examples of systems are water molecules, galaxies, and babies. The two most common types of galaxies are globular galaxies and spiral galaxies. Essentially this means that surveys of deep space could be showing us multiple images of the same finite set of galaxies - this is like being in a hall of mirrors. If galaxies themselves were like kinetic sculptures, or if they were arranged with each other like kinetic sculptures, this would be confirmation of design - but the apparent chaos is not. The main challenge here is to find out how these galaxies manage to convert so much gas into stars so efficiently and in such a very short time. In the same way, they can contribute to our developing understanding of phenomena associated with other galaxies. From the Hansard archive Example from the Hansard archive.
