In beta decay, an antibuetrino or an positron is emitted from the nucleus. how is this possible? how can antimatter come directly from matter? This is pizzling...

Beta decay is a type of radioactive decay in which a nucleus emits a beta particle, which can be either an electron or a positron (an antiparticle of an electron).
Antimatter is composed of antiparticles, which have the same mass as their corresponding particles but opposite charge. For example, an antielectron (or positron) has the same mass as an electron but a positive charge instead of a negative charge.
In beta decay, a nucleus can emit a positron, which is an antiparticle of an electron. This positron then combines with an electron, resulting in the annihilation of both particles and the creation of two gamma rays. This process creates equal amounts of matter and antimatter.
The creation of antimatter through beta decay is puzzling because it violates the law of conservation of symmetry. According to this law, all physical processes should result in equal amounts of matter and antimatter, but this is not the case in beta decay.
Studying beta decay and antimatter can lead to a better understanding of the fundamental laws of physics and the origins of the universe. It can also have practical applications in medical imaging and cancer treatment, as well as in the development of advanced propulsion systems for space exploration.
