Abstract
In early 2013, a group of researchers led by French scientists published in Nature a paper entitled “A vast, thin plane of corotating dwarf galaxies orbiting the Andromeda galaxy” [69]. This paper reported new intriguing observations that showed that a majority of the dwarf galaxies which orbit the larger Andromeda galaxy was actually rotating in a very thin, common plane structure. These observations then contradicted the state-of-art models which assumed that dwarf galaxies’ locations followed an isotropic random distribution. This discovery raised many fundamental open questions that can potentially reshape the entire understanding of the universe formation process, as it implies that a still-to-be-found phenomenon seems to control the geometry of cosmos gas flow.
