@jeanniewu88: Recent research suggests that Earth, along with the Milky Way, may reside inside an enormous cosmic void about 2 billion light-years across. This region, sometimes called a “supervoid” or the KBC Void, is significantly less dense than the average universe, containing roughly 20% less matter. The evidence comes from analyzing Baryon Acoustic Oscillations, which act as a standard ruler in cosmology; distortions in these patterns indicate that our local region is unusually empty compared with the cosmic average. If confirmed, this could help explain anomalies like the differing measurements of the universe’s expansion rate, known as the Hubble tension. #nasa Source 1. - https://academic.oup.com/mnras/article/540/1/545/8129689 Source 2 - https://academic.oup.com/mnras/article/536/4/3232/7924235
