Why does the weak nuclear force matter if it is so short-range?
Quick Answer
The weak force is short-range, but it is crucial for radioactive decay and for nuclear reactions that power stars. Without it, many important transformations between particles would not happen.
The Full Story
The weak nuclear force acts over distances much smaller than an атом nucleus, yet it is fundamental in particle physics. It allows processes such as beta decay, where a neutron changes into a proton, electron, and antineutrino. This force is also involved in the fusion chain that powers the Sun, because some steps require the weak interaction. Though weaker than electromagnetism and the strong force, it changes particle types and helps shape the elements in the universe. The force was unified with electromagnetism in the electroweak theory, developed in the 20th century.
