The concept of a "weird material" made of subatomic particles is quite broad, so I'll provide a general answer based on our current understanding.
In particle physics, scientists have discovered a wide range of materials composed of subatomic particles. These materials are typically referred to as states of matter or exotic states of matter. Some examples include:
Quark-Gluon Plasma: At extremely high temperatures and densities, such as those found shortly after the Big Bang or in heavy-ion collisions at particle accelerators, it is theorized that quarks and gluons, which are fundamental particles, can exist in a deconfined state known as quark-gluon plasma. Quark-gluon plasma is a state of matter where individual quarks and gluons are not bound within protons and neutrons, but instead, they move freely. Scientists have been able to create and study quark-gluon plasma in particle accelerator experiments.
Condensed Matter Systems: Condensed matter physics deals with the behavior of large ensembles of particles, such as atoms or electrons, and their interactions. In this field, scientists have discovered a variety of exotic materials with unique properties. For example, materials exhibiting superconductivity, where electrical resistance disappears at low temperatures, or materials with topological properties, which give rise to unusual electronic behavior.
Exotic Composite Particles: Particle physics also studies composite particles formed by the combination of subatomic particles. For instance, mesons are composite particles made up of a quark and an antiquark, while baryons, such as protons and neutrons, consist of three quarks. Discovering new composite particles or uncovering unexpected properties of known composite particles can lead to novel materials with distinct properties.
It's important to note that our understanding of subatomic particles and their interactions continues to evolve. As research progresses, there is always the potential for new discoveries and the emergence of novel materials or states of matter that may exhibit strange or unexpected properties. Scientific exploration and experimentation play a crucial role in expanding our knowledge of the fundamental building blocks of matter and their behavior.
