Dark energy is the name given to the strange power that causes the universe to accelerate over time instead of slowing down. Dark matter is particles that cannot absorb, reflect or emit light, from which they cannot be detected; They make up 85 percent of the matter in the universe and a quarter of its mass.
New findings from the Institute of Particle and Nuclear Studies (IPNS) at the University of Tokyo and the Max Planck Institute for Astrophysics (MPA) examine the background of microwave radiation in the universe following the Big Bang and their symmetry.
The current laws of physics assume that one system will function in the same way as it does in another system where all spatial coordinates flip. This symmetry is called “parity”.
However, if it is possible to violate this symmetry, it could reveal more information about the mysterious dark matter and dark energy in the universe.
This background showed potential violations in radiation. 400,000 years after the initial explosion, light from the Big Bang became “polarized” when scattered by electrons.
This is similar to how invisible light from the sun becomes polarized when scattered by water droplets in the atmosphere and forming a rainbow.
As light travels through the universe, it interacts with dark matter and dark matter, and the plane of polarization can rotate.
“If dark matter or dark energy interacts with cosmic microwave background light in a way that violates symmetry, we will find its signature in the polarization data,” said Yuto Minami, a postdoctoral fellow at IPNS.
Scientists used a polarization-sensitive detector in the Planck satellite to measure the rotation angle, with knowledge of how polarization-sensitive detectors target the sky.
This histor has been historically challenging; Uncertainties about the rotation caused by the detectors have overtaken previous measurements of the cosmic polarization angle.
Scientists have discovered that the distance traveled by light from the dust inside the galaxy is shorter than that of ancient light, meaning that it is not affected by dark matter or dark matter.
“We have developed a new method for determining artificial rotation using polar light through dust in our galaxy,” Minami said.
“With this method, we’ve got an accuracy that’s twice as much as previous work, and we’re finally able to measure. [the rotation angle]”.
Unfortunately, the violation of equality symmetry was observed only with a 99.2 percent confidence level. For a new discovery to be valid, it must have a confidence level of 99.99995 percent.
“It is clear that we have not found definitive evidence for new physics; High statistical significance is required to confirm this indication. But we are excited because our new method has finally allowed us this ‘impossible’ criterion, which could point to a new physics, “said Ichiro Komatsu, director of the MPA and chief investigator at IPMU. The research was published in Physical Review Letters On November 23.
Scientists have suggested that dark energy may be the global ‘culmination’ – a substance, rather than the stability of space before it.
“I think we should probably go through all of that carefully before we work too hard,” said Mark Kamionkowski, a theoretical physicist who researched Satkarma in 1998. Nature.
If it were found to be true, it would completely change human understanding of the laws of physics, which does not predict any kind of contribution. It could also change the recorded age of the universe, calculated based on data collected by the Planck Institute. However, the research supporting it is not currently as strong as it is acceptable.
