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.

  • cosmic-microwave-background
  • recombination-era
  • dark-ages
