Anyone sending a space shuttle into orbit, building a skyscraper, or even studying bone density owes a debt of gratitude to Isaac Newton and his theory of gravitation and laws of motion. Yet, the role of gravity in life’s processes, from cell structure to the human cardiovascular system remains unclear. Judith Kampfner explores the enigma force by starting in an eight grade science class, following a high school physics class as they perform some experiments on NASA’s vomit comet, and interviewing science historian Robert Smith from University of Alberta, the Smithsonian Air and Space Museum’s James Zimbelman and NASA scientists who are creating environments with artificial gravity.
