Early Universe
The study of the early universe focuses on understanding the first stages after the Big Bang, including cosmic inflation and the formation of matter. Key elements include:
- Cosmic Microwave Background (CMB) - Remnants from about 380,000 years post-Big Bang.
- Recombination Era - The period when electrons combined with protons to form hydrogen atoms.
- Dark Ages - A phase where no stars or galaxies existed yet, the universe was dark and filled primarily with neutral hydrogen gas.
Key Concepts
- cosmic-microwave-background
- recombination-era
- dark-ages
- populations-of-stars
Recent Discoveries
- Potential detection of Population III stars in GN-z11 by the James Webb Space Telescope (JWST).
- Evidence suggests these are among the universe’s first generation of stars.
- Observations indicate a significant step towards understanding early star formation and chemical enrichment.
