Planetary pressure cooker: how gas and rock give birth to oceans ⚡ экспресс
Original: "Experiments reveal extreme water generation during planet formation"
Lab experiments recreated the interiors of rocky worlds and showed how hydrogen and molten rock produce water on the scale of tens of Earth's oceans.

Deep inside pressure-cooker planets, superheated hydrogen collides with blazing rock — and gives birth to water. New experiments have shown: such 'water factories' can be hidden inside the most common worlds of the Galaxy, rewriting the story of their evolution.
🎯 If the young Earth had managed to hold onto its hydrogen envelope, it would have 'cooked' its own global ocean — no comets needed.
