A team of physicists at Stockholm University and the Max Planck Institute for Physics have proposed a theory to prove the dark matter. For the ones who are unaware of the term dark matter, it is the most abundant matter in the entire universe. It comprises 85% of all the bodies that exist in entire universe. The term was coined to explain why the force between proton and neutron has not changed since the beginning.
To explain this invisible matter, physicists have proposed a new axion that shall provide evidence of the dark matter. According to this axion is present not in the form of a discrete particle. Instead, it has a continuous wave-like pattern. The scientists have developed a new device that can listen to the sound produced by the matter.
How the Device Can be Helpful in Identifying the Dark Matter?
According to Dr. Alexander Millar finding an axion is somewhat similar to tuning into a radio. One must need to find the correct frequency to listen to the sound. In this experiment, instead of music, the scientists will hear the sound of the dark matter traveling through space. The major propulsion of the experiment depends on the generation of an electromagnetic field produced by the axion. This EM field can fuel oscillation which can amplify the signals for scientists to tune into axion radio.
As per Dr. Matthew Lawson, plasma has a dual and a crucial role in finding proofs of the axion and further the dark matter. It creates an optimal environment for conversion axions into light and provides resonant plasmons that can collect the energy of the dark matter.
To quantify their proposal, scientists have developed a device called “wire metamaterial”. It uses a system of wires that are even thinner than human hair and can change the characteristics of the plasma.
