What was discovered
A vast region of the local universe with a galaxy density markedly below average, about 2 billion light-years across, identified by astronomers Ryan Keenan, Amy Barger and Lennox Cowie.
Its existence remains a matter of scientific debate; some studies question whether the underdensity is as pronounced, or as real, as proposed.
What it led to
- possible partial explanation for the Hubble constant tension
- influence on the study of the universe's large-scale structure
- subject of debate over its real existence relative to surrounding structures
