Dancing galaxy led scientists to doubt the model of the Universe

Swiss scientists at the University of Basel discovered orbiting a lenticular galaxy Centaurus a dwarf galaxy satellites.

Their orderly rotation (“dance”) forced astronomers to question the modern concept of cosmological LCDM (Lambda-Sidim, Lambda-Cold Dark Matter). The article was published in the journal Science, it leads Scientific American.

Instead of trying to follow random orbits, 14 of 16 dwarf galaxies revolve around Centauri A in the same orbital plane. LCDM, which includes dark matter and dark energy in the Universe, suggests that the small galaxies scattered around the larger randomly and move in different directions.

The exceptions to this are considered to be the milky way and the nearest galaxy is Andromeda, which is synchronously rotating galactic satellites. Centaurus a, thus, became the third galaxy.

If star clusters-coplanar satellites (synchronous) orbits will be detected in other galaxies, it will be a serious challenge in the modern sense of the model with dark matter. However, scientists from Basel noted that the study of other dwarf galaxies will take decades.

The LCDM model assumes the existence in the Universe is not only a normal matter, but dark energy and cold dark matter. This model estimates the age of the Universe almost 14 billion years, it includes inflation, but also considers the General theory of relativity the correct theory of gravity at cosmological scales.
