According to physicists, only about 4.4% of what we can see and see in space.
68.6% are 'dark energy' which is repulsing in space expansion, and 27% have mass and are not observed by electromagnetic waves such as radio waves, infrared rays, visible rays, ultraviolet rays, X rays, and gamma rays. Dark matter.
Dark matter candidates include Axion, neutrinos, and WIMPs. Major research institutes, such as the European Institute for Particle Physics (CERN), are working to identify these candidates and have recently identified the identity of Axion.
Particle rumble, mathematically equivalent to axion
Science News reported on Tuesday that it found a semi-particle hidden in crystals at the Max Planck Institute of Physical and Chemistry in Dresden, Germany.
Quasiparticles refer to the collective excitation of particles.
In general, in a multiparticulate group of particles that have no size and only have properties such as mass, position, and velocity, the particles can not move independently because of the forces acting on each other.
However, when the temperature decreases, the effect is to change the state of the surrounding particles. When the central particle moves, the surrounding particles move along with it. There are several particles like this, but because one particle appears to move, it is called a semi-particle.
The quasi-particle was found in a substance called 'Weyl semimetal'.
German mathematician Hermann Weyl confirmed that the solution of the Dirac equation, the equation of relativistic quantum mechanics, depends on a special condition, and the metal that meets this condition is called the "Bail Semimetal."
According to Dr. Johannes Gooth, the leading researcher at the Max Planck Institute, basic particles called Weyl Fermions are located in the "Bail Semimetals."
These particles, which seem to have no mass, form crystals when the temperature drops. The team succeeded in applying a strong electric and magnetic field to these crystals, causing a sloshing similar to the standing waves of the charge.
And it was confirmed that this rocking was mathematically identical to Axion.
The team measured the current flowing in the crystal to confirm that this slump was occurring, and said that it could be seen as rapidly increasing as the electric field force became stronger.
Uncover the truth of Axion that was considered impossible
In the meantime, scientists have observed the cosmic time-shifting and gravitational effects of fermion particles with physically unusual asymmetry. The research is drawing attention from the scientific community as it uncovers the reality of axion, which some scientists have considered impossible.
The paper was recently published in the journal Nature. The title of the paper is 'Axionic charge-density wave in the Weyl semimetal (TaSe4) 2I'.
Axion was named in 1977 by Professor Frank Wilczek of MIT, the 2004 Nobel Prize for Physics.
At the time, a company was using a detergent brand called 'Axion', meaning 'to wash everything clean'. Professor Wiltuck took the brand name and used it as a newly proposed dark matter candidate.
According to the Axion theory, a number of axions were generated during the big bang process of the universe.
However, in the ensuing cosmic expansion, mass is generated and significant amounts of kinetic friction force are absorbed and all of the axial energy of Axion is absorbed. And the universe is filled with a very cold condensate called axion.
Scientists have been looking for axion to prove this theory by using powerful magnets, high-frequency resonators, and cryogenic device technology in particle accelerator laboratories like CERN.
The results of the Max Planck Institute's research reveal the existence of quasi-particle axion in quantum mechanics. Dr. Johannes Gotz expressed his joy, saying, "Axion, which has existed only as a mathematical concept, can confirm that it can actually exist."
Dr Helen Quinn, a theoretical physicist at the Stanford Linear Accelerator Center (SLAC), said, “A phenomenon like the Doppelgängers, where the same person appears in different places at the same time, It appeared through. ”
She worked with Dr. Roberto Peccei in 1977 to develop a theory that scientists can no longer mathematically access the truth of dark matter.
