i just learned that quarks are always paired with antiquarks, and i wonder what effect keeps them from turning into energy? is it some kind of quantum pressure? thanks

Quark-antiquark pairs do not annihilate because they possess opposite charges. In the Standard Model of particle physics, quarks have a positive charge and antiquarks have a negative charge. When a quark and an antiquark come into contact, their opposite charges cancel each other out and they are able to coexist without annihilating.
Quark-antiquark pairs can form through various processes, such as the decay of a larger particle or the splitting of a gluon. They can also be produced in high-energy collisions, such as those that occur in particle accelerators. In these collisions, the energy is converted into mass, allowing quark-antiquark pairs to be created.
Yes, under certain conditions, quark-antiquark pairs can annihilate. This typically occurs when they are in a highly excited state or when they are subject to extreme temperatures and pressures, such as those found in the early universe. In these cases, the energy of the particles is high enough to overcome their opposite charges and they can annihilate.
Gluons, which are the particles that mediate the strong force, play a crucial role in preventing quark-antiquark annihilation. The strong force is responsible for holding quarks together within particles, and gluons are constantly exchanged between quarks and antiquarks, keeping them bound and preventing annihilation.
Yes, there are several theoretical explanations for quark-antiquark annihilation. Some theories propose that there may be particles beyond the Standard Model, such as supersymmetric particles, that could cause quark-antiquark annihilation. Other theories suggest that there may be extra dimensions or new forces at play that could lead to annihilation. However, these theories have not yet been confirmed and are still being researched.
