Geon (physics)

Geon (physics) is a type of particle that was first proposed by physicist Arthur Eddington in the 1920s. It is a particle which is believed to be the basic building blocks of all matter in the universe. To put it simply, geons are tiny pieces which combine together to make atoms, which are the smallest pieces of matter which we can see and measure. Geons have no known size, shape, or mass.
