Multiverse Might Not Be as Inhospitable to Life as Previously Thought

A new study has come up with the collaborative research of different universities which tells that regardless of the truth of the Multiverse hypothesis, life can survive outside the Universe in which humans live.

In order to arrive at this conclusion, the research team used giant computer simulations that ended up suggesting that if other universes exists they would be equally likely to harbor 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 handsome galaxies which permit life as we know it", saidLuke Barnes of Western Sydney University.

The team claimed that even if the universe has 100 times more dark energy than our universe, stars and planets still have time to form - increasing the possibility that Alien life may exist outside of our own universe.

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.

They said that it doesn't matter how much dark energy exists, it could be hundred thousand of our own universe. However, the likelihood that we'd even be able to expand beyond our own universe is extremely low - leading many to hope that we'll eventually discover alien life a little closer to home.

We would expect to see up to 50 times more in our cosmos based on the multiverse theory, they said.

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

Although the results do not rule out the Multiverse, it seems that the tiny amount of dark energy in our Universe would be better explained by an, as yet, undiscovered law of nature.

So, do we need more dark energy inside our universe?

The main theory about dark energy is that our universe was created by a short burst, and this explosion made it expand rapidly.

"The formation of stars in a universe is a battle between the attraction of gravity, and the repulsion of dark energy", said team member Professor Richard Bower, of Durham University.

The Multiverse is a hypothetical group of numerous separate Universes, including the one where humans reside.

"I think we should look for a new physical law to explain this unusual characteristic of our universe, and the theory of multiverses has little effect on the discomfort of saving physicists".

It may sound far-fetched but the concept is the subject of serious debate among physicists. Stephen Hawking's final theory of the cosmos, completed only weeks before his death in March, stated that reality may be made up of multiple universes.

Dark matter is thought to be the gravitational "glue" that holds the galaxies together.
