👉 The term "axion" is used to describe a hypothetical particle that has been proposed by physicists. It is currently considered an elementary particle, but it may have the potential to be fundamental in physics.
It's important to note that the concept of an "axion" is still being studied and debated by scientists, and its existence remains uncertain. The discovery of axions would require a more detailed understanding of quantum field theory, which is currently at the forefront of research in physics.
