Scientists Find Oxygen Source at Depth of 4000 Meters

Scientists have found an oxygen source at a depth of 4000 meters - previously this was considered impossible as there is no light and no photosynthesis occurs. At first, it was attributed to a sensor error, but 10 years of research confirmed the hypothesis - at the bottom of the Pacific Ocean lie rocks capable of converting water into oxygen. This discovery completely changes everything we know about life on Earth, and possibly on other planets.
