Astronomers have created 8 million universes inside a computer. And here is what they learned

Despite numerous assumptions aboutthat our Universe is a computer simulation, in fact, the probability of this is extremely small. However, nothing is impossible in the world, therefore scientists can very well observe the most different forms of life in millions of Universes. In theory. In fact, astronomers created eight million Universes on a computer. The fact is that the simulation of the origin and further development of universes can tell a lot about ours.

The greatest mystery of the universe

If every time you think about the universeand about what it is, it seems to you that you don’t know anything and don’t understand what is really happening there - this is normal. It is incredibly difficult for our brain to comprehend such concepts as infinity, lanaka and the event horizon of a black hole. And when it comes to dark matter, you get the feeling that dark matter is the greatest mystery of our Universe.

Laniakeia is a supercluster of galaxies. Translated from Hawaiian, this word means "immense heaven."

At least scientists today adhere tojust such a point of view. The aim of the researchers in creating 8 million computer simulations of the Universes was to understand what role this mysterious substance has played in the life of our Universe since the time of the Big Bang.

The diameter of Laniakei is approximately 520 million light-years

It is believed that shortly after the birth of the universe,the invisible and elusive substance, called “dark matter”, was transformed by massive gravity into massive clouds called the halo of dark matter. As the halo grew in size, they attracted rare gaseous hydrogen permeating the universe to unite and form the stars and galaxies that we see today. In this theory, dark matter acts as the basis of galaxies, determining the processes of formation, fusion and development over time.

To better understand what effect on the formationDark matter provided the universe, scientists from the University of Arizona created their own universes using a supercomputer. 2000 processors worked without interruption for three weeks, simulating more than 8 million unique universes. Surprisingly, each Universe obeyed a unique set of rules to help researchers understand the connection between dark matter and the evolution of galaxies.

The greatest computer simulation

Study Published in Monthly MagazineNotices of the Royal Astronomical Society and is the first in its field. Previously, scientists created single simulations that focused on modeling individual galaxies. The new program is called Universe Machine. She continuously created millions of universes, each of which contained 12 million galaxies. Moreover, all these millions of universes have evolved from the Big Bang to the present day.

This may look like a computer simulation of the universe

According to experts, the most interestingis that now scientists can use all available data on the evolution of galaxies - their number, number of stars and methods of star formation - and combine them into a comprehensive picture of the last 13 billion years of the universe. Note that creating an exact copy of our universe or even a galaxy would require incredible processing power. Therefore, scientists have focused on two key properties of galaxies: the total mass of stars and the speed of star formation.

According to the study, the speedstar formation of stars in a galaxy is closely related to the mass of the halo of dark matter. In those galaxies where the mass of the halo of dark matter was similar to the halo of dark matter of the Milky Way, the star formation rate was the highest. This suggests that in more massive galaxies, star formation is constrained by a large number of black holes.

Astronomers' observations cast doubt onscientists' assumptions that dark matter suppresses star formation in the early Universe. In fact, smaller galaxies are more likely to form stars with greater speed.

In the future, scientists plan to expand UniverseMachine, to work out even more options in which dark matter can affect the properties of galaxies, including the form of their development, the mass of black holes and the frequency of conversion of stars into supernovae.

Dizzying, isn't it? Do you think scientists can solve the greatest mysteries of the universe?
