“Dance in zero gravity completely transforms how we think about choreography and performance,” says Sydney Skybetter, the founder of the Conference for Research on Choreographic Interfaces and director of the Brown Arts Institute at Brown University. “When you remove the floor, which is the fundamental organizing principle of terrestrial dance, bodies become three-dimensional sculptures moving through space multi-axially.” And whether dance artists are exploring movement in microgravity theoretically or literally, the relationship between dance and space brings up myriad questions—creative, logistical, and ethical.
