Current theories, however, predict there should be rather more of it around than there appears to be.
Hypothesis 1980-ies about the Multiverse provides that our universe, which is only one of many, is able to reveal the secret of the right amount of dark matter, which influenced the origin of life. The researchers acknowledge that their results do not preclude it - but they do diminish the likelihood.
Dark energy is a mysterious, invisible force thought to exist in the empty spaces of our universe. Dark energy affects the universe expansion.
"We have found in our simulations that universes with much more dark energy than ours can happily form stars".
"The multiverse theory tries to explain these fine-tuned constants as a lottery". The multiverse theory states that different worlds in the multiverse have the different percentage of dark energy, but luckily we have the comparatively low amount of dark energy for our survival.
"For many physicists, the unexplained but seemingly special amount of dark energy in our Universe is a frustrating puzzle", Salcido said. "Our simulations show that even if there was much more dark energy or even very little in the universe then it would only have a minimal effect on star and planet formation, raising the prospect that life could exist throughout the multiverse".
Dark matter may be played an essential role in the formation of earliest stars, but according to some researchers that suggest that the mysterious and invisible material may also have been a significant factor for creating black holes. "Stars today form in giant clouds of molecular gas and dust embedded in the disks of large galaxies like our Milky Way, whereas the first stars emerged inside "minihalos", agglomerates of primordial gas and dark matter with a total mass of a million times that of the Sun", Volker Bromm of the University of Texas wrote in a commentary.
"The existence of life seems to depend on a small number of "fine-tuned" fundamental physical constants, such as the strength of gravity and the amount of dark energy", Salcido added. It finds support among some of the world's most accomplished physicists, including Brian Greene, Max Tegmark, Neil deGrasse Tyson and the late Stephen Hawking.
Research by Durham University and several of its partner universities in Australia have concluded that a hypothetical "multiverse", in which our universe is one of many, could be far more hospitable to the development of life than was previously thought. "We have a lucky enough ticket and live in the universe that forms attractive galaxies which permit life as we know it".
"Our work shows our ticket seems a little too lucky, so to speak".
Erin VanDyke lives on her family farm and has more than 35 years of hands-on experience with the use of livestock guard dogs for predator control. "This is an issue for the Multiverse; a baffle remains". The secret, according to the authors of a new research conducted by Durham University, is dark energy, a puzzling "force" which is hastening the Universe's expansion. In such a scenario, life as we know it would not have formed, and the universe would be, in that sense, dead, like the rest of the multiverse which has the theoretically higher amount of dark energy.
The scientists found that their findings were surprising and may be troubling given that they raise questions regarding the potential of a Multiverse theory to shed light on the perceived amounts of dark energy.
Despite the fact that the outcomes don't discount the Multiverse, it appears that the minor measure of dim vitality in our Universe would be better clarified by an, up 'til now, unfamiliar law of nature.
