    The multiverse is a cosmological idea according to which the universe in which we are is only one of several universes, one in which the amount of dark energy is that mysterious force that represents more than 68 percent of the total energy in the observable universe and causes its acceleration expansion is unexpectedly low. The amount of dark energy, lower than predicted by the theories of the origin of the universe, also remains a factor that allows life to exist in our universe, but not in the rest of the multiverse. It is believed that our universe is fortunate because if there had been more dark energy, the universe would have expanded much faster than it did, and the matter would have been too diluted to join and form stars and planets. In such a scenario, life as we know it would not have been formed, and the universe would be, in that sense, dead, like the rest of the multiverse that has the theoretically highest amount of dark energy. But a new simulation of the cosmos shows that even dark energy levels hundreds of times higher than those observed in our universe would not prevent the formation of stars and planets. Therefore, many other universes in the multiverse could possibly also harbor life forms. Jaime Salcido, a graduate student at the Institute of Computational Cosmology at the University of Durham in the United Kingdom, and lead author of a research paper on the subject said in a statement on Sunday: "For many physicists, the amount inexplicable but apparently special dark energy in our the universe is a frustrating puzzle Our simulations show that even if there were much more dark energy or even very little in the universe, it would only have a minimal effect on the formation of stars and planets, which raises the possibility that life can exist throughout the multiverse. " In addition to raising the possibility of life that exists elsewhere beyond the universe, there is another impact that the results of the simulation have, in the theory of the multiverse itself, to which scientists like the late Stephen Hawking subscribed. Since the theory was partially formulated to explain the apparent anomaly between the theoretical and observed quantities of dark energy in the universe, in relation to the formation of stellar and planetary bodies, it now seems to have lost its main reason for existing. "It used to be that the multiverse explained the observed value of dark energy as a lottery: we have a lucky ticket and we live in the universe that forms beautiful galaxies that allow life as we know it." Our work shows that our ticket looks like a little too lucky, so to speak, it's more special than it needs to be for life, this is a problem for the multiverse, a puzzle remains, "Luke Barnes, a researcher at the University of Western Sydney, Australia, said in the statement. , and coauthor of the newspaper. The simulation does not rule out the multiverse theory but suggests that a still unknown law of physics could better explain the amount of dark energy observed in our universe. Two research papers based on the simulation findings will be published in the Monthly Notices of the Royal Astronomical Society.
