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

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

Radio cosmologists from around the globe have been stuck to their sets for a considerable length of time to tune in to that one sound from some place in space which would demonstrate that an outsider life, adequately propelled, exists some place in our universe.

It was generally understood that any more presence of dark matter than the amount present in our universe would create such rapid expansion that stars and planets wouldn't be able to form - but scientists at Durham University claim that it might not be so simple, and that alien life may be possible as a result.

Current theories posit that our universe has just the right amount of dark energy to support life.

Using massive computer simulations of the cosmos, the researchers discovered that the addition of dark energy (as much as a few hundred times the amount that is observed in our Universe) would have a significant impact on planet and star formation. "This is a problem for the Multiverse; a puzzle remains".

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

"We asked ourselves how much dark energy can there be before life is impossible?".

"Even increasing dark energy many hundreds of times might not be enough to make a dead universe", added Pascal Elahi from University of Western Australia.

" I believe we must be searching for a brand-new law of physics to discuss this unusual residential or commercial property of our Universe, and the multiverse theory does little to rescue physicists' pain.".

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. The dark energy is defined as the unusual force, which is triggering the universe to expand. Most of the experts have said the parallel universes to be non-supporters of the evolution of life.

"The formation of stars in a universe is a battle between the attraction of gravity, and the repulsion of dark energy", saidRichard Bower of Durham University.

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

"I think we should be looking for a new law of physics to explain this odd property of our Universe, and the Multiverse theory does little to rescue physicists' discomfort", he added.

The concept of our universe being one among many others has interested many scientists to debate on it.

But researchers behind the new study said their finding casts doubt on a multiverse explaining the value of the mysterious substance of dark energy. What does the future of our Universe hold?
