Output: yes


Input: Consider Input: Question: Is the dynamic representation of gravity suspended when the idiotropic vector is misaligned with gravity?
Answer: The dynamic visual representation of gravity is neither purely body-referenced nor world-referenced. It seems to be modulated instead by the relationship between the idiotropic vector and physical gravity.


Output: yes
