Story summary
  • Astronomers have discovered two massive cosmic structures—the giant arc and the big ring—that challenge cosmological models.
  • The giant arc spans 3.3 billion light-years.
  • The big ring measures 1.3 billion light-years in diameter.
  • Both structures exceed theoretical size limits, prompting researchers to rethink the universe's formation.
  • Alexia Lopez led the studies and urged surveys to understand these anomalies and their implications for dark matter and galactic evolution.
