The Milky Way is the galaxy that houses the Earth. Now, have you ever wondered why it is shaped like a spiral? A new theory could change everything.
The study of galaxies allows us to understand how their formation occurred and, of course, what their outcome could be in the medium term. If we think for a moment about its formation, it is very possible that its spiral-shaped silhouette comes to mind. Now, have this set of planets, stars and satellites always been like this? A new investigation has sought to shed light on this matter. Among the conclusions that have been produced, it is worth highlighting that they could have looked more like a lentil in the past.
Let us see, therefore, what are the characteristics that can be suggested of this formation, why we are faced with a form that could raise future studies and, of course, to what extent we are facing a starting point that could lead to new results. When could the spiral shape that characterizes most of them occur?
Galaxies could have a silhouette similar to a lentil in their beginnings
The published study suggests that at some point in the particularly long lives of galaxies, they are born as “lenticular” options, that is, shaped like a lentil. It is later when they change shape with the passage of time to become elliptical spots. The Milky Way, home of our Planet, could have followed this same trend described. This is a new theory that could completely change the origin that, today, is believed to have occurred.
Generally, each galaxy has one or more black holes. Therefore, when two galaxies end up merging, These matter absorbers also end up doing it. Graham, of the Swinburne University of Technology at Hawthorn, studied images provided by the Hubble and Spitzer satellites. He was able to check more than 100 galaxies and, except for “lenticular” ones, black hole mass and stellar mass tended to be linked in predictable ways.
This researcher states that The collision between galaxies turns them into dust-rich lenticulars. After the passage of time, they end up eroding, producing this spiral-shaped trail. This new theory, if confirmed with new data, could change the way we understand the origin of the Universe. This is an alternative that should be considered in order to understand our own origin and, of course, what could await us in the future in the event of a potential collision with our neighboring galaxy, Andromeda.
It is expected that over the next few months it will be possible to carry out new lines of research with the aim of obtaining answers to new questions that this theory is proposed. Even so, it seems that it is still too early to say that we are facing a study that could turn everything previously done by the scientific community and the corresponding consensus that existed upside down.
