👉 charmonium is a concept in cosmology that refers to an object, thought to be composed of two different types of particles, called "charmonium". These particles are believed to have been created by the process of quantum tunnelling, where the energy levels of these particles were allowed to transition between states. The charmonium particles are hypothesized to form a unique and exotic quantum state that is not well understood or described in traditional quantum mechanics. Charmonium is often considered a theoretical
