Episode notes
Local Cosmic Void Could Skew Expansion Rate
- Astronomers propose the Milky Way may sit inside a billion-light-year region with ~20% fewer galaxies than average.
- This local underdensity could explain the Hubble tension by making nearby expansion appear faster.
Void Dynamics Can Mimic Faster Local Expansion
- A central void would gravitationally pull surrounding denser regions, emptying the center over time.
- That process would make local galaxy velocities appear higher, creating a measurement distortion.
Huge Scale Means Little Local Impact
- The hypothesized void needn't be empty—just ~20% less dense than average across ~1 billion light years.
- Even if true, its enormous scale means it wouldn't practically affect life in our galaxy.
