The European Organization for Nuclear Research (CERN) announced the discovery of the first exotic particle, consisting of four heavy quarks of the same type.
Quarks are the building blocks of hadrons, including protons and neutrons. They usually come together in groups of two and three. Although in recent years, researchers have confirmed the existence of several exotic hadrons, consisting of four or five, but several types.
Studying the data of experiments at the Large Hadron Collider, scientists have recorded the formation of a new class of particles, which physicists have never met before. They represent the first tetraquark, which consists of two heavy charmed quarks and two similar antiquarks…
The discovery will help physicists better understand the basic building blocks of matter and test current fundamental theories. Scientists cannot yet determine for sure whether the new part is an integral or weakly structure of two pairs of quarks, like a molecule..

In addition to research at the quantum level, scientists are also studying unusual types of materials in space objects. For example, astrophysicists recently discovered a new type of matter inside neutron stars.
