In this episode of Cosmos in a Pod, we explore gravitational lensing—a breathtaking cosmic phenomenon where massive objects bend and magnify light, revealing hidden wonders of the universe.

Key Highlights

• What Is Gravitational Lensing?
  • The bending of light by massive objects like galaxies, is predicted by Einstein’s general relativity.
  • Acts as a natural magnifier, uncovering distant and faint cosmic objects.
• Types of Lensing:
  • Strong Lensing: Creates Einstein rings and multiple images.
  • Weak Lensing: Subtle distortions reveal dark matter.
  • Microlensing: Detects small objects like rogue planets.
• Why It Matters:
  • Maps dark matter  ...
