The anomaly was found in the Central and Northern Pacific, but researchers suspect it may be present globally.
Beryllium-10 is typically produced by cosmic rays interacting with Earth’s atmosphere and is deposited in ocean crusts over millions of years.
The
unexpected spike in Beryllium-10 levels suggests a significant event
occurred during this period. Possible explanations include a major
reorganization of ocean currents, a nearby supernova, or Earth’s passage
through an interstellar cloud, which could have increased cosmic ray
activity and Beryllium-10 production....<<<Read More>>>...
