Physicists’ brand-new proposition that a brand-new kind of additional dark energy is included is highlighted in clinical journal.
The universe was developed by a huge bang; the Big Bang 13.8 billion years earlier, and after that it began to broaden. The growth is continuous: it is still being extended in all instructions like a balloon being pumped up.
Physicists settle on this much, however something is incorrect. Measuring the growth rate of deep space in various methods results in various outcomes.
So, is something incorrect with the techniques of measurement? Or is something going on in deep space that physicists have not yet found and for that reason have not considered?
“A new type of dark energy can solve the problem of the conflicting calculations.”
— Martin S. Sloth, Professor
It might effectively be the latter, according to numerous physicists, i.a. Martin S. Sloth, Professor of Cosmology at SDU.
In a brand-new clinical post, he and his SDU associate, postdoc Florian Niedermannn, propose the presence of a brand-new kind of dark energy in deep space. If you include it in the numerous estimations of the growth of deep space, the outcomes will be more alike.
“A new type of dark energy can solve the problem of the conflicting calculations,” states Martin S. Sloth.
Conflicting measurements
When physicists compute the growth rate of deep space, they base the computation on the presumption that deep space is comprised of dark energy, dark matter and common matter. Until just recently, all kinds of observations harmonized such a design of deep space’s structure of matter and energy, however this is no longer the case.
Conflicting results develop when taking a look at the most recent information from measurements of supernovae and the cosmic microwave background radiation; the 2 techniques rather merely result in various outcomes for the growth rate.
“In our model, we find that if there was a new type of extra dark energy in the early universe, it would explain both the background radiation and the supernova measurements simultaneously and without contradiction,” states Martin S. Sloth.
From one stage to another
“We believe that in the early universe, dark energy existed in a different phase. You can compare it to when water is cooled and it undergoes a phase transition to ice with a lower density,” he discusses and continues:
“In the same way, dark energy in our model undergoes a transition to a new phase with a lower energy density, thereby changing the effect of the dark energy on the expansion of the universe.”
According to Sloth and Niedermann’s estimations, the outcomes build up if you envision that dark energy hence went through a stage shift set off by the growth of deep space.
An extremely violent procedure
“It is a phase transition where many bubbles of the new phase suddenly appear, and when these bubbles expand and collide, the phase transition is complete. On a cosmic scale, it is a very violent quantum mechanical process,” discusses Martin S. Sloth.
Today we understand approx. 20 percent of the matter that deep space is made from. It is the matter that you and I, worlds and galaxies are made from. The universe likewise includes dark matter, which nobody understands what is.
In addition, there is dark energy in deep space; it is the energy that triggers deep space to broaden, and it comprises approx. 70 pct. of the energy density of deep space.
