Episode notes
Dark Matter Is Massive But Mysterious
- Dark matter makes up roughly 25–27% of the universe and is detected only via gravity.
- We know little about its particle nature or exact local distribution despite strong astrophysical evidence.
Locally Dark Matter Density Is Extremely Low
- If dark matter is smoothly spread through the galaxy, local density is tiny: about 10^-22 kg/m^3.
- That implies only ~0.66 kg of dark matter inside Earth's volume under that assumption.
Why Dark Matter Forms A Fuzzy Halo
- Dark matter forms a large, diffuse halo around galaxies rather than collapsing like normal matter.
- Without nongravitational interactions it stays puffy and doesn't clump into stars or planets.
