Is there life in the multiverse?

Multiverse theory cops a blow after dark energy findings

Multiverse's High Dark Energy Levels Don't Hamper Life's Chance Of Existing Elsewhere

The multiverse idea to an extent accounts for and accommodates this oddly small - but life-permitting - dark energy quotient.

However, the researchers said their results came unexpected and could cause a problem on their ability of the multiverse theory to explain the observed amount of dark energy.

As per the exploration, on the off chance that we live in a Multiverse, we'd hope to watch considerably more tiresome vitality than we do - maybe 50 times more than we find in our Universe.

From the research conducted by Durham University in collaboration with three other Australian universities-the University of Sydney, the Western Sydney University and the University of Western Australia, the research proposed that the increase in the amount of dark energy by a few hundred times would only have a decent effect on the formation of planets and stars. Since higher levels of dark energy would still allow life in the universe to exist, this hints at the possibility that life could also have appeared in other universes despite their estimated greater percentage of dark energy.

A "multiverse" - where ours is among many - would not be as inhospitable as previously believed, say astronomers.

In turn, this suggests that the Multiverse, if it in fact exists, could be teeming with life, EurekAlert reports.

In 2014, meanwhile, hackers were able to access private photographs belonging to celebrities before posting them online. Recode and MSNBC asked Cook how he would have handled the situation if he was Facebook CEO Mark Zuckerberg.

This is the conclusion reached by the experts, modelling multiple universes with different amount of dark energy.

"For many physicists, the unexplained but seemingly special amount of dark energy in our universe is a frustrating puzzle", says Salcido.

The Multiverse theory states that our universe is only one in a large number of possible universes that have sparked into existence after the Big Bang.

"The formation of stars in a universe is a battle between the attraction of gravity, and the repulsion of dark energy", explained physicist Richard Bower of Durham University. However, modern cosmology can not answer the question about the existence of life in other universes, since the studies conducted earlier suggested that a greater amount of energy will expand "nearby" worlds, which will not be planets, galaxies and stars.

Now new research led by Durham University, UK, and Australia's University of Sydney, Western Sydney University and the University of Western Australia, has shown that life could potentially be common throughout the Multiverse, if it exists.

The team created simulations of the universe using the supercomputer architecture contained within the Evolution and Assembly of GaLaxies and their Environments (EAGLE) project.

"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".

"Our work shows that our ticket seems a little too lucky". This theory served to explain the reason behind the low amount of dark energy found in our universe. "So why such a paltry amount of dark energy in our Universe?" asks Prof.

"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.

As Barnes puts it, "our ticket" is "more special than it needs to be for life [to exist]".

But the tiny amount may be better explained by an, as yet, undiscovered law of nature. "This is an issue for the Multiverse; a baffle remains".

"It seems that we need a new physical law to understand dark energy", Salcido said.

South Africa's Vodacom cuts dividend payout after earnings miss
Seven-million customers were added to Vodacom's network - 4.5-million in South Africa and 2.5-million in the global operations. Group service revenue increased 3.4 percent to ZAR 70.6 billion and was up 5.1 percent on an adjusted basis.

"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".
