Scientists have identified which galaxies are more suitable for intelligent life. For example, according to their theory, the chance of their existence in giant elliptical galaxies is extremely low.
Gigantic elliptical galaxies are almost not adapted to the life of intelligent creatures – this was stated by astrophysicists from the University of Arkansas. An article published in the Monthly Notices of the Royal Astronomical Society magazine contradicts a 2015 study, which stated that the chances of life in giant elliptical galaxies are 10 thousand times greater than in galaxies with spiral disks.
The change in probability is due to the fact that earlier researchers took into account the presence of a large number of stars in giant elliptical galaxies and low rates of potentially deadly supernovae. However, Daniel Whitmere, a professor of astrophysics and one of the leading authors of the study, believes that this study violates a statistical rule that states that in the absence of evidence to the contrary, an object or some property of an object should be considered typical of its class.
“The 2015 publication had a serious problem with the principle of consistency”, said Whitmere. “In other words, every time you discover that you stand out, that is, atypical, your case is exceptional – then this is a problem for the principle of consistency”.
Previously, scientists discovered many spiral galaxies in the early Universe – previously it was believed that they could not exist at that time. This is stated in a study by scientists from the Laboratory of Astrophysics of Marseille, published in the journal Astrophysical Journal.
