The life cycles of stars—fusion, collapse, and supernova explosions—further enriched the interstellar medium with heavier elements like carbon, oxygen, and iron, essential building blocks for planets and life. Each phase represents a fundamental shift in the universe’s physical properties, governing everything from the formation of subatomic particles to the emergence of complex chemistry.

Key Elemental Abundances Element Approximate Abundance Hydrogen ~75% by mass Helium ~25% by mass Lithium & Beryllium <1% by mass The Dark Ages and the First Light Following nucleosynthesis, the universe entered a period known as the Dark Ages, which lasted for millions of years. Galaxies formed within dark matter halos, and stars were born within these galactic nurseries.
This framework describes the evolution of the universe from its initial moment of hot, dense expansion to the present day, where galaxies drift apart in a vast, cooling expanse. During this time, the universe was filled with neutral hydrogen gas, and no stars had yet formed to pierce the cosmic gloom.
The Star Birth Process in Big Bang Theory Stages
The Initial Singularity and Rapid Inflation All big bang theory stages originate from an initial point of infinite density and temperature, a condition where the known laws of physics break down. This stage represents the ongoing process of cosmic assembly, where smaller structures merge to form larger ones.
