Primordial Universe

The primordial universe refers to the earliest stages of the cosmos before the formation of galaxies and stars. This era was characterized by extreme conditions including high temperatures and density, leading to the development of the first matter from particles.

Key Concepts

• Big Bang: The initial singularity marking the beginning of time and space.
• Cosmic Microwave Background (CMB): Radiation left over from an early stage in the universe’s expansion.
• Dark Ages: Period following the recombination era when the universe was dark due to a lack of luminous sources.

Recent Developments

• On 2026-04-12, Anton Petrov discussed groundbreaking evidence for Population III stars (video). These theoretical stars are believed to be the first generation of stars in the universe.
  • The James Webb Space Telescope (JWST) detected signs of Population III stars in GN-z11, a galaxy at redshift z=11.09 (source).
  • This discovery marks a significant milestone in understanding the early universe and its evolution.
