Prior to 1989, it was commonly assumed that virialized galaxy clusters were the largest structures in existence, and that they were distributed more or less uniformly throughout the universe in every direction.

Both the COBE ripples and the large - scale clustering of galaxies can be explained by a CDM universe in which 80 per cent of the present mass density is contributed by a cosmological constant, though some cosmologists argue that such theories may not explain the motions of galaxies.

The discovery that many small galaxies throughout the universe do not «swarm» around larger ones like bees do but «dance» in orderly disc - shaped orbits is a challenge to our understanding of how the universe formed and evolved.

If there is any large amount of antimatter in the universe, it must encompass at least an entire galaxy cluster, and probably a supercluster.

Thanks to the dry, clear atmosphere at the South Pole, SPT is better able to «look» at the cosmic microwave background — the thermal radiation left over from the Big Bang — and map out the location of galaxy clusters, which are hundreds to thousands of galaxies that are bound together gravitationally and among the largest objects in the universe.

Analysis of the newly found quasar shows that a large fraction of the hydrogen in its immediate surroundings is neutral, indicating that the astronomers have identified a source in the epoch of reionization, before enough of the first stars and galaxies have turned on to fully re-ionize the universe.

@Amir: Too late too much money is already been spent but you can explain the formation of galaxies and overall large scale structures of the material in the universe.

However, in the smaller, early universe, some growing black holes and nearby stars might have merged before the heavens were stretched out leaving extremely large MBHs in small galaxies.46

still can't easily account for a large number of mature or massive galaxies in the early universe.»

The idea goes like this: Early in the universe's history, large galaxies grew out of collisions and mergers of smaller galaxies.

«Even though the Large Magellanic Cloud is one of our nearest galactic companions, we expect it should share some uncanny chemical similarity with distant, young galaxies from the early universe,» said Marta Sewiło, an astronomer with NASA's Goddard Space Flight Center in Greenbelt, Maryland, and lead author on a paper appearing in the Astrophysical Journal Letters.

The merging of small galaxies into larger ones is common throughout the universe, but because the shredded galaxies are so faint it has been hard to extract details in three - dimensions about how such mergers proceed.

Galaxies are not scattered randomly throughout the universe, but are often found in «clusters,» which are in turn parts of larger groupings called «super-clusters.»
