The Gravity Problem

ABSTRACT Advanced Rolfing Instructor Jan Sultan outlines his definition of gravity, informed by physicist Dr. John Archibald Wheeler and founder of Rolfing Structural Integration Dr. Ida P. Rolf. According to Sultan, Rolf would talk about the ‘Line’ as a logo of relationship as a teaching tool for practitioners to think about mass, density, and gravity. Rolf taught that humans have a tropistic urge, an innate sense to go away from the planet. Yet Sultan urges Rolfers to think beyond Newtonian terms to Wheeler’s spacetime definition of gravity, where spacetime grips mass and mass grips spacetime. This leads Sultan to inquire if the mind has mass.
