The consensus is that the universe was created in a giant bang – known as the Big Bang – about 13.8 billion years ago, and then began to expand. All signs indicate that the universe continues to stretch in all directions like an ever-expanding balloon.
However, consensus among physicists about the birth and life of the universe strikes a chord beyond this point. The rate of global expansion appears to vary according to how it is measured.
The way we measure universal expansion could be wrong, or something could be happening in the universe that physics has not yet discovered – throwing away their models.
The latter may be so, according to a recent study published in the journal Corporate Review D.. In the study the authors suggest a new type of dark energy in the universe. When this new type is introduced into the global expansion calculation, you will get results with more in common than before – reducing the schism in consensus.
A new kind of dark energy may explain the expansion of the universe
“A new kind of dark energy can solve the problem of controversial calculations,” said Professor of Cosmology Martin S. Sloth of the University of Southern Denmark (SDU), in a Science every day report.
When physicists try to measure the extent of the expansion of the universe, they assume that the universe is made up of three parts: dark matter, dark matter, and normal matter. Until recently, all sorts of observations worked with this model of power and the issue of the universe – but this may no longer be true.
Variable results in the calculation of global expansion occur when physics looks at the latest data from measurements of the background radiation of cosmic supernovae or microwave. Both methods have different levels of product expansion.
“In our model, we find that if there were a new type of extra dark energy early in the universe, it would explain both the background radiation and the supernova dimensions at the same time. time and without contradiction, “Sloth said.
“We believe that, early in the universe, dark energy was at a different level. You can compare it to when water has cooled and it goes through a phase change to ice with density. lower, “Sloth explained. “Similarly, dark energy in our model undergoes a transition to a new level with lower energy density, thus reversing the impact of dark energy on global expansion.”
Stopping the ‘phase movement’ of dark energy could strengthen consensus on the extent of global expansion
Sloth researcher and postdoctoral Florian Niedermann – an associate at Sloth at SDU – said their calculations work, while you think dark energy experienced a level shift caused by expansion the universe.
“It’s a phase transition where a lot of bubbles of the new level suddenly appear, and when those bubbles expand and collapse, the phase transition is complete,” he said. Sloth. “On a cosmic scale, it’s a very violent quantum mechanical process.”
As of writing, we know what makes up about 20% of the world’s population. This is a normal case, which makes up all of us, the planets, the stars, and the galaxies. But there is also a dark subject in the universe – which so far has avoided all empirical study.
The third element – dark energy – is the energy that is thought to stimulate global expansion – making up about 70% of the earth’s energy density. Although the universe has no secrecy, by building a better consensus in our calculations about what it is made of, how it works, and when dark energy passes through a phase shift that could bring us closer to a coherent understanding of the extent of cosmic expansion.
