Big Bang

The Big Bang is a scientific theory that describes the origin and early development of our universe. It suggests that around 13.8 billion years ago, all matter in existence was concentrated into an incredibly small point called a singularity. From this moment, the universe rapidly expanded, causing temperatures to drop and allowing particles to form.

Key Concepts

• Singularity: The initial state of the universe where density and temperature were infinite.
• Cosmic Microwave Background (CMB): Radiation left over from an early stage in the universe’s history, providing critical evidence for the Big Bang model.
• Expansion of the Universe: Observations showing that distant galaxies are moving away from us at speeds proportional to their distance.

Recent Discoveries

• In 2026, the James Webb Space Telescope (JWST) detected compelling evidence for Population III stars in the galaxy GN-z11. These primordial stars were formed during the universe’s earliest stages and are theorized to have been composed entirely of hydrogen and helium.
