Aliens exist but may be in a parallel universe

And the new research suggests that the answer lies in dark energy, the mysterious "force" that is accelerating the expansion of our Universe.

In their research, dark energy (opposite of gravity) appeared as a crucial factor. So why such a paltry quantity of dark energy in our universe? But given the levels of dark energy in our Universe, there is likely a natural law we have yet to discover.

The result of collaborative research between a number of universities shows that life can survive outside our Universe, regardless of the Multiverse hypothesis.

"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.

The idea that our universe is just one of many, perhaps infinite, other universes is known as the multiverse theory.

"We found in the simulation that the universe, which is much darker than our energy, can happily form stars".

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.

"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 new simulation demonstrates, even in case there is a huge amount of dark energy or very little presence of dark energy, it has a very less impact on the formation of planet and stars, which rise the hope of existence of life in other multiverses as well".

However, Jaime Salcido, a masters student from the Durham's Institute for Computational Cosmology, thinks that the multiverse theory inly indicates that our own universe is one of many. These researchers were running a programme called "Evolution and Assembly of Galaxies and their environments".

Their findings are released in 2 associated documents in the journal Regular monthly Notifications of the Royal Astronomical Society.

The fact that the universe continues to expand means that it creates a multiverse: it is essentially our own infinite cosmic supply.
