We could be living in a multiverse with alien neighbours, suggests study

We could be living in a multiverse with alien neighbours, suggests study

Scientists are yet to agree on the existence of a multiverse where our universe is only one of many, but if it does, it might not be as inhospitable to life as previously thought. "Even increasing dark energy many hundreds of times might not be enough to make a dead universe", added Elahi. 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. Appending massive amounts would lead to such a speedy growth that it would lessen the matter before any stars, planets or life could form.

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.

"We found in the simulation that the universe, which is much darker than our energy, can happily form stars". And they find out that Dark energy plays an important role to form such conditions.

"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".

Their findings are released in 2 associated documents in the journal Regular monthly Notifications of the Royal Astronomical Society. The team comprising researchers from England, Australia and the Netherlands came to this conclusion after running a programme called "Evolution and Assembly of Galaxies and their Environments".

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

Why gas prices will keep rising this summer
Analysts say the gas prices nationwide are close to hitting $3 per gallon for the first time since 2014, when it averaged $3.62. Florida's most expensive gas is unfortunately right here in Tallahassee and in West Palm Beach.

Hidden Pages In Anne Frank's Diary: Corny Jokes And Sex Ed
The black and white photos of a young Anne Frank along with her diary helped her to become a worldwide symbol of the Holocaust. Frank's candid words on sex didn't make it into the first published diary, which appeared in English in 1952.

The dark energy issue has been a hot topic of research by scientists and it has become clearer and clearer that we do not have a firm grasp of its function - it turns out that we may be wrong about the limitations of energy everywhere.

The main theory regarding dark energy asserts that our universe was created with a brief burst that allowed it to expand at a rapid pace. This shows that the universe is still expanding in some areas and will continue to grow indefinitely.

In doing so, it produces multiverses: an endless supply of universes similar to our own, inhabited with Earthlike worlds, societies as well as people that resemble us.

"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".

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. There is the possibility of formation of many another universe parallel to us and they can also sustain life.

This latest study proves that it may eventually find the lives of aliens - leaving behind a lot of optimistic information, that is, at certain times we do find that we are not alone.
