Cosmic Abundance

Cosmic abundance refers to the relative amounts of different elements and particles found throughout the universe. It helps scientists understand what materials are most common in stars, planets, and interstellar space. For example, hydrogen and helium are by far the most abundant elements because they were primarily formed during the Big Bang. Heavier elements like carbon, oxygen, and iron are less common and mostly created in stars through nuclear fusion. Studying these abundances provides insights into the universe’s origins, evolution, and the processes that shape the cosmos over time.
