A multiverse is a group of multiple different universes which also comprises our universe where we live. According to multiverse theory, only our universe has come into existence after the big bang in compare to other vast possible universes. Many scientists like Alan Guth, Neil deGrasse Tyson, Stephen Hawking, was a proponent of this theory. This theory served to explain the reason behind the low amount of dark energy found in our universe.
In the early 1990’s, theorists came up with many sorts of explanations about dark energy, according to them there is some field that creates cosmic acceleration, and they have given the solution a name. It is called dark energy. Dark energy affects the universe expansion. It turns out that roughly 68% of the universe is dark energy.
However, some new theories suggested that there is more amount of dark energy in our universe. This throws light on a mistake in calculations which predicts that dark energy would expand the universe at a faster rate for stars, planets to form, meaning we wouldn’t exist.
According to Cosmos magazine, the multiverse theory helps to explain this calculation. 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.
The multiverse theory, proposed in the 1980s, suggested that surprisingly we have the low amount of dark energy that allows us to live, which is not seem in other universes. A postgraduate student from Durham University’s Institute for Computational Cosmology said that in our universe the unexplained dark energy looks like an irritating puzzle.
From the research of Cosmos university, dark energy at its observed value, has a negligible impact on star and planets formation in the universe. Also from the studies in the Monthly Notices of the Royal Astronomical Society have also supported this fact that dark energy is not only the primary reason behind the formation of stars and planets.
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.
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.
Also, most physicists believed that dark energy, whose presence is only due to the gravitational impact on celestial objects is likely to make up most of all the universe. Ordinary matter, which we can feel or see makes up the rest of the part. “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.
From the reports of Eureka Alert, the higher amount of dark energy would still allow life to exist; this indicates the feasibility of life could be visible in another universe also having, the higher percentage of dark energy.
Columbia University physicist Brian Greene describes the idea as the notion that “our universe is one of potentially numerous ‘slabs’ floating in a higher-dimensional space, much like a slice of bread within a grander cosmic loaf,” in his book “The Hidden Reality.”
Dr. Luke Barnes, a John Templeton Research Fellow at Western Sydney University, said that previously multiverse thought to explain the value of dark energy as the lottery. He continues that we live in a universe full of beautiful galaxies, which grants us life and this is our lucky ticket.
“Our work shows that our ticket seems a little too lucky. It’s more special than it needs to be for life. This is a problem for the Multiverse; a puzzle remains.” Was also said by Dr. Lukes Barnes
Another researcher Dr. Pascal Elahi, at the University of Western Australia, suggested that the accelerated expansion driven by dark energy doesn’t have any impact on the formation of stars. Even increasing the amount of dark energy would not be enough to make a universe dead.he also questions that how much dark energy will be there before life is impossible.
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.
According to the research, if would like to expect to notice much more dark energy than we do, if we live in a Multiverse –it would be 50 times more than we observe in our universe. It seems that the tiny amount of dark energy in our Universe would be better explained by an, as yet, the undiscovered law of nature. The results do not rule out the multiverse.
“The formation of stars in a universe is a battle between the attraction of gravity, and the repulsion of dark energy ‘ as said by Professor Richard Bower, in Durham University. From many stimulations, it has been found that other universes with much more value of dark energy than our universe can easily form stars and planets. So why such an insignificant amount of dark energy for our universe.
However, some other experts are not convinced by the multiverse idea and even believed that as there is not much point on debating about it and there is no real proof about life on multiverse or can we survive on it. But after so many researches it looks like life is possible in the multiverse, and there are other many multiverses which are habitable.Tags: multiverse, universe
