    Extraterrestrial life could exist in other universes, according to a group of scientists who study a mysterious force known as dark energy. Previous theories suggested that our universe has the perfect amount of dark energy, which acts against gravity and is causing the cosmos to expand at an accelerated rate. It was understood that any other would create an expansion so fast that the stars and planets would not have time to form. The theory of the multiverse was presented for the first time in the 80s. But researchers at the University of Durham say that these celestial bodies would still have formed, even if a universe had 100 times more dark energy than ours. They used giant computer simulations to suggest that, if other universes exist, they are likely to harbor life. "The formation of stars in a universe is a battle between the pull of gravity and the repulsion of dark energy," said Professor Richard Bower, of the Institute of Computational Cosmology at the University of Durham. "We have found in our simulations that universes with much more dark energy than ours can happily form stars, so why such an insignificant amount of dark energy in our universe?"I think we should be looking for a new law of physics to explain this strange property of our Universe, and the multiverse theory does little to rescue the discomfort of physicists." Their findings are published in two related articles in the Monthly Notices of the Royal Astronomical Society. And their simulations were created using the EAGLE project (Evolution and assembly of galaxies and their environments), one of the most realistic programs that map the observed universe. The enigma of dark energy has plagued scientists for years, said Jaime Salcido, a graduate student at the University of Durham.
    He added: "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." The theory of eternal inflation widely accepted states that our universe began to exist with a brief explosion that caused it to expand at a rapid pace. Some suggested that this meant that, in some regions, the universe is still expanding and will continue to grow infinitely. In doing so, create multiverses: an endless supply of universes like ours, populated by planets, societies and even Earth-like people who resemble us.
