Why We’ve Mapped So Little Seafloor

The ocean covers seventy percent of Earth but we've only mapped twenty seven percent of

the seafloor in high resolution. The reason is wild. Insane pressure crushes submarines

like tin cans. Total darkness kicks in below two hundred meters. Freezing temperatures

and super expensive tech make it harder than exploring space. Yet we've already discovered glowing

creatures and entire ecosystems thriving in impossible conditions. New technology is finally speeding

things up and scientists believe we're on the edge of finding things that could change everything

we know about life itself.
