Scientists discover oxygen source on ocean floor, challenging beliefs

ABC News — July 24, 2024, 01:00 AM UTC

Summary: Scientists have discovered a new source of oxygen on the ocean floor, four kilometers deep, where sunlight cannot reach. This "dark oxygen" is produced by metallic deposits, challenging the belief that oxygen is solely generated by photosynthesis. The findings suggest that these deposits may generate electric charges, splitting water into hydrogen and oxygen. This discovery could reshape theories about the origins of life on Earth and beyond.

I'm replacing the original 8-factor scoring system with a new and improved one. It doesn't use the original factors and gives much better significance scores.
