In weightlessness, “down” cues from the inner ear otolith organs are absent. Astronauts are thought to rely more heavily on vision. Many astronauts perceive a “subjective vertical”. When it changes direction, it can cause disorientation and motion sickness

Human Visual Orientation in Weightlessness Charles M. Oman Man Vehicle Laboratory, Massachusetts Institute of Technology, Cambridge, MA 02139 Abstract: An astronaut's sense of self-orientation is relatively labile, since the gravitational “down” cues provided by gravity are absent and visual cues to orientation are often ambiguous, and familiar objects can be difficult to recognize when viewed from an unfamiliar aspect.

“One should beware of mathematicians and all who make empty prophecies. The danger already exists that the mathematicians have made a covenant with the devil to darken the spirit and confine man in the bonds of Hell” St Augustine, Bishop of Hippo, circa 400 A.D “To move things is all that Mankind can do…For such the
