Baryon density refers to the number of baryons, such as protons and neutrons, per unit volume in the universe, which plays a crucial role in understanding the matter content and evolution of the cosmos. It is a fundamental parameter in cosmology, influencing the formation of structures and the synthesis of elements in the early universe.

Number of baryons

Protons and neutrons are the fundamental particles that make up the nucleus of an atom, with protons carrying a positive charge and neutrons being neutral. Together, they determine the atomic mass and the identity of the element, playing a crucial role in the structure and stability of matter.

Synthesis of elements

The early universe refers to the period immediately following the Big Bang, characterized by rapid expansion and cooling that led to the formation of fundamental particles and eventually atoms. This era set the stage for the development of cosmic structures such as galaxies, stars, and planets through processes governed by fundamental forces and cosmic inflation.
