Episode notes
Dark Matter Properties and Evidence
- Dark matter is invisible and intangible, making up 80% of the universe's matter.
- We know it exists through its gravitational effects, like holding galaxies together.
Galaxy Rotation and Dark Matter
- Galaxies spin too fast to hold stars without dark matter's extra gravity.
- Evidence suggests there's 4-5 times more gravity than visible matter can explain.
Dark Matter Distribution and Lensing
- Dark matter, unlike normal matter, doesn't clump together but forms a foam-like structure.
- Its gravity holds galaxy clusters together, evidenced by gravitational lensing.
