Multiverse Might Not Be as Inhospitable to Life as Previously Thought

High dark energy levels in Multiverse doesn't mean life can't exist outside our Universe

According to a new pair of studies in the journal Monthly Notices of the Royal Astronomical Society, there's a decent chance that life-fostering planets could exist in a parallel universe - even if that universe were being torn apart by dark energy. 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 previously proposed theory of dark energy shows that our universe has "perfect" dark energy - a resistance against gravity, which is responsible for making the universe expand at a faster rate.

Even when the simulated universe contained hundreds of times more or less dark energy than there is in our universe, planets and stars still formed and life evolved.

Using state-of-the-art computer simulations, a research team led by Durham University, Western Sydney University, and the Universities of Sydney and Western Australia has found that adding dark energy, up to a few hundred times the amount observed in our Universe, would actually have a modest impact upon star and planet formation.

Cosmologists from the Durham University in the United Kingdom and Australia's University of Sydney, Western Sydney University, and the University of Western Australia used huge computer simulations of our observed universe to examine how different levels of dark energy might affect the development 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.

The finding also causes major problems for the idea of multiverse.

Our work shows that our ticket [to living in a universe that permits life] seems a little too lucky, so to speak.

Missing Commonwealth Athletes, Coach Face Deportation From Australia
The Refugee Advice and Casework Service in Randwick says some of the 11 athletes have asked for help with visas. Before the games came to an end, several athletes from African nations failed to participate in the events.

"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".

If we live in a Multiverse, we'd expect to observe much more dark energy than we do - perhaps 50 times more than we see in our Universe. Most of the experts have said the parallel universes to be non-supporters of the evolution of life.

"We have found in our simulations that universes with much more dark energy than ours can happily form stars".

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 can not be done appropriately by the theory of Multiverse.

We can't go beyond our own universe to find the lives of aliens, but this new knowledge of dark energy may adjust the way we look for ways in the future. "So why is there so much dark energy in our universe?"

Luke A. Barnes et al. But the formation of galaxies and other universes is not limited to that.

In general, it is clear that our understanding of dark energy is lacking.
