Aliens may well exist in a parallel universe, new studies find

Alien life might exist in other universes, inning accordance with a group of scientists studying a mystical force referred to as dark energy. One of the questions posed by this hypothesis is whether other Universes could harbour life.

"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 attractive galaxies which permit life as we know it", saidLuke Barnes of Western Sydney University.

"We asked ourselves how much dark energy can there be before life is impossible?" said Pascal Elahi, another research fellow of the same Australian university. Appending massive amounts would lead to such a speedy growth that it would lessen the matter before any stars, planets or life could form.

Current theories suggest our universe contains the "perfect" amount of dark energy to sustain life, the Daily Mail reports.

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.

The search for alien life has always been a priority for many scientists and enthusiasts alike, and the fact that this alien life is quite likely to exist outside of our universe is comforting in a way.

The multiverse theory was first advanced in the 80s. 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.

The multiverse theory suggests that our cosmos is one of a number of different "alternate" universes.

The findings will be published across two papers in the Monthly Notices of the Royal Astronomical Society.

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.

"I think we should be looking for a new law of physics to explain this unusual property of our Universe, and the Multiverse theory does little to rescue physicists' discomfort". And they find out that Dark energy plays an important role to form such conditions.

The number of universes could be infinite, meaning there are infinite versions of reality, some of which are very similar to our own. Numerous researchers have long argued that the idea is not possible to test.

The European Space Agency says: 'Shine a torch in a completely dark room, and you will see only what the torch illuminates.

"Similarly we know dark matter exists but have never observed it directly".

Just five per cent the observable universe consists of known material such as atoms and subatomic particles.
