Summary

Story summary

New research indicates a local cosmic void, potentially addressing the Hubble tension of a 10% faster universe expansion.
Baryon acoustic oscillations (BAOs) measurements reveal a matter density in our region approximately 20% lower than average.
The study, published in the Monthly Notices of the Royal Astronomical Society, calls for improved BAO measurement accuracy.
Findings suggest a universe with a local void is more probable than one without.
