Astronaut Shubhanshu Shukla breaks down how orbit really works
Shubhanshu Shukla shared a post on why floating in space is falling forever. Drawing from Newton's thought experiment and his own ISS experiences, he simplified orbit and weightlessness, winning praise for making complex science easy to understand. He highlighted astronauts don't feel weightless because gravity disappears and that gravity at ISS is still about 90% as strong as on Earth.
