science π Earth's core might hold enough hydrogen for 45 oceans
Scientists found that Earth's core contains a significant amount of hydrogen through advanced lab simulations. The research team, led by Dongyang Huang at Peking University, used high-pressure experiments to analyze core material. These calculations estimate the core's hydrogen content is between 0.07% and 0.36% by weight, based on samples. This quantity is enough to form 9 to 45 new Earth oceans if scaled up. This suggests a large portion of Earth's water might have formed internally rather than from comet impacts. π
