In a mind-bending study, researchers have revealed that multiverse may support alien life and we might not be alone in theory. The study is an outcome of a team of researchers from- Australia’s University of Sydney, Western Sydney University, the University of Western Australia, and Durham University, UK.
The concept of our universe being one among many others has interested many scientists to debate on it. The idea of the Multiverse has engaged even the philosophical thinkers and the fiction writers. Many of the researchers have long argued that the idea is not possible to test. Most of the experts have said the parallel universes to be non-supporters of the evolution of life.
A Masters student from the Durham’s Institute for Computational Cosmology, Jaime Salcido said that the theory of multiverse indicates our universe to be just one among many others. He further said that the multiverse concept shows baby universes getting birth like that of bubbles in a huge multiverse with many fundamental constants and physical laws. He further added that just a small portion of the “baby universes” take birth so that they possess the adequate quantity of “dark energy,” something that is required to support life. The dark energy is defined as the strange force, which is triggering the universe to expand. Salcido further said that the evolution of life forms depends on a few basic physical constants like “the quantity of dark energy and the strength of gravity.” Salcido explained that the evolution of the galaxies and the stars are the end result of a “tug-of-war in between the quantity of dark energy and the strength of gravity: the former causing the universe to fly apart and the latter causing matter to clump together.”
The simulations were produced under the Evolution and Assembly of GaLaxies and their Environments (EAGLE) project.
“The Multiverse was previously thought to explain the observed value of dark energy as a lottery — we have a lucky ticket and live in the Universe that forms beautiful galaxies which permit life as we know it,” said co-lead author Dr. Luke Barnes, a researcher at Western Sydney University and the University of Sydney.
“Our work shows that our ticket seems 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.”
“We asked ourselves how much dark energy can there be before life is impossible? Our simulations showed that the accelerated expansion driven by dark energy has hardly any impact on the birth of stars, and hence places for life to arise,” said co-lead author Dr. Pascal Elahi, a scientist at the University of Western Australia.
Jaime Salcido, a postgraduate understudy in Durham University’s Institute for Computational Cosmology, stated: “For some physicists, the unexplained however apparently exceptional measure of dull vitality in our Universe is a baffling riddle.
“Our reproductions demonstrate that regardless of whether there was substantially more dim vitality or even next to no in the Universe then it would just minimally affect star and planet development, raising the prospect that life could exist all through the Multiverse.”
The research depicted that if humans would be live in a Multiverse then they should be observing near about fifty times higher dark energy that they are doing at the present. The research does not tend to entirely falsify the Multiverse idea, however, it just says that tiny quantity of dark energy present in the universe that humans live in could be explained better by the help of a natural law, which is yet to be discovered.
Researcher Richard Bower of the Durham University said that according to him, a “new law of physics” should be looked for in order to completely explain the mysterious “property of our Universe,” which cannot be done appropriately by the theory of Multiverse.
Scientist Richard Bower, in Durham University’s Institute for Computational Cosmology, stated: “The development of stars in a universe is a fight between the fascination of gravity, and the aversion of dim vitality.
“We have found in our reproductions that universes with substantially more dim vitality than our own can joyfully frame stars. So why such a negligible measure of dim vitality in our Universe?
“I figure we ought to search for another law of material science to clarify this interesting property of our Universe, and the Multiverse hypothesis does little to safeguard physicists’ inconvenience.”
