Our bodies function necessarily under the presence of gravity; how blood pumps, a sense of balance and bone growth are all due to life in a world where gravity is an inescapable reality. Armed with experiments from neuroscientists David Hubel and Torsten Wiesel, astronaut Jay Buckey presents a thought experiment: How would our bodies work without the force of gravity?
TEDed video created and narrated by Jay Buckey. Directed by Biljana Labovic. Animated by Godfrey Hibbert, Lisa LaBracio, and Celeste Lai.
