What was discovered
The CfA redshift survey revealed that galaxies are distributed in filaments and sheets surrounding huge voids: the 'cosmic web'.
The Boötes void (1981) was one of the first pieces of evidence.
What it led to
- SDSS and 2dF surveys
- Simulations of structure formation
- Baryon acoustic oscillations
