Extra-dimensional particles can form the mysterious dark matter

Science currently has four forces of normalization. cosmologists Standard Form In this way he explains the creation of the universe and derives the work of the universe so far observed. Among the forces constituting the world, strong interaction holds together the protons of the nucleus and the neutrons of the quarks; The weak interaction is responsible for the beta decay of radioactive decay, the decay of a free neutron, and in some atoms the decay of a proton and a neutron, respectively; Electromagnetic interaction is the effect of an electromagnetic field on charged particles. The intermediate particles of these forces are now known to be bosons, known as gluon for strong interactions and photons for electromagnetic interactions.

The fourth fundamental interaction, the force of gravity, is the least explored force of naturalization: because until now we have only been able to name, find and discover the main intermediate particle in the interaction – called the graviton. That’s why it’s a slight scientific fuss new theoryAccordingly, the fabric of dark matter, which benefits the mass of the known universe but is perceived only indirectly, consists of gravitational intermediate particles called the supermassive graviton.

The particles that make up dark matter that are supposedly attracted to visible matter are cosmic remnants of extra dimensions, according to LiveScience, published in Phisical Review Letters. just described study. Giacomo Caciapaglia, theoretical physicists at the University of Lyon, Hyeing Kai and Seung-Gi Lee of Seoul University in Seoul, searched for gravitons as they searched for evidence of three known dimensions and an additional dimension long assumed over time.

According to them, “the spread of gravity through additional dimensions is embodied in our universe in the form of massive gravitons, but they interact with visible matter only through gravity.”

The researchers’ calculations show that within the picosecond after the Big Bang – just 001,000,000,000,000 seconds) – many massive gravitons formed that explain the amount of dark matter detected in the universe. The researchers say the gravitons they assume weigh less than 1 megaelectronvolt (MeV), which is twice the mass of an electron. (The lightest known particle, the neutrino, weighs less than 2 MeV, while the proton weighs about 940 MeV.)

The theory, like the theories of strong and weak interactions, can be proven in particle accelerators. According to the three theoretical physicists, massive gravitons formed in the lower energy scale of the Higgs boson, which gives matter mass. Experimental validation of high-performance particle accelerators such as those planned for publication at CERN by 2035 could be achieved. futuristic ring collider.
