Episode notes
Early Galaxy Formation
- The James Webb Space Telescope (JWST) reveals galaxies forming much earlier than previously thought.
- This challenges the established timeline of the Big Bang theory.
Redness and Age
- Redness in JWST images indicates age in distant galaxies.
- These images show galaxies forming earlier than expected, prompting reflection on the universe's timeline.
Dark Matter and Structure Formation
- The early galaxy formation challenges our understanding of dark matter's impact on structure formation.
- It questions the interplay between baryonic matter and dark matter in galactic evolution.
