The universe is shrouded in mystery, can there be another life in it? Since time immemorial, scientists have been trying to understand our "place" in the vastness of the universe. This search has led many astronomers - and philosophers in ancient times - to become interested in whether humans are the only living species or not. This idea inspired the imagination and interest of scientists, philosophers, historians, archaeologists and ordinary people.

Although we still have no idea how big the universe is, where we are in it and what is around us, most people would agree with the statement that due to the massive size of the universe, we know that it is big, but we do not know how big! For that reason it is absurd to think that we are the only living species.

As I have already written in various articles, our universe is so large that it is difficult to grasp it in a reasonable perspective. Now, for a moment, imagine that like other solar systems, there are other universes. This idea, or rather the theory, is referred to as parallel universes. Imagine these endless possibilities if scientists really find evidence of other universes.

It now appears that, according to two scientific studies published in the Monthly Announcements of the Royal Astronomical Society there is a chance that life may exist on planets located in parallel universes. As I explained above, the notion that our universe is just one of many - perhaps endless universes - is known as the theory of multiverse (multiversia; pozn.).

An international group of scientists ran a massive computer simulation to create new universes under various conditions, where the determining factor was dark energy. The surprise of the authors has shown that life can arise in more scenarios than scientists have expected.

Dark energy - the key to multiverse? A graph depicting the distribution of dark energy in the universe

According to scientists, dark energy is a mysterious and invisible force existing in the "empty" spaces of our universe. This is often referred to by experts as archnemesis (as a judge of retribution in an extreme counterattack; pozn.) of gravity. While gravity closes all matter, the dark energy separates it. And according to the astrophysicists, the other in the series wins the cosmic battle.

According to the best estimates of the current cosmological model, dark energy contributes practically 69 percent to the total mass and energy of the universe. As experts explain, this amount is, for some reason, suitable for the development of the galaxy and the maintenance of life in it. It is supposed that if we lived in a space with too much dark energy, the evolution of the universe would be faster as the origin and development of new galaxies. And conversely, if there was a lack of dark energy, gravity would cause the galaxies to collapse in themselves before they could even be created as such. It's like cosmic equilibrium.

Life in multipurpose

After several experiments and simulations, an international group of scientists from England, Australia and the Netherlands used the "Evolution, meeting of galaxies and their environment", Which simulated the birth, life and eventual death of several hypothetical universes. In each simulation performed by experts, the amount of dark energy was set, ranging from zero to several hundred times the amount existing in our universe. Scientists have found that even in universes where 300 is more and more dark energy than ours, we have survived our lives.

Jaime Salcido, a postgraduate student at the Institute of Computational Cosmology at Durham University, said:

“Our simulations have shown that accelerated expansion, driven by dark energy, hardly has any effect on the birth of stars and hence places for life. Even increasing dark energy by many hundreds of times may not be enough to create a dead universe. ”

According to recent studies, we should expect that if we are part of a multipurpose, we should see far more dark energy than at present - about 50 times more than we see in our universe. Professor Richard Bower of the Institute of Computational Cosmology at Durham University said:

“Star formation in the universe is a struggle between gravitational attraction and repelling dark energy. In our simulations, we found that universes with much greater dark energy content can happily form stars. So why such a small amount of dark energy in our universe? I think we should look for a new law of physics that explains this strange feature of our universe, and the multiverse theory has not helped us much so far.
