The fastest rotation rate for a space colony that would allow most of the inhabitants to feel comfortable instead of suffering from motion sickness is:
- 1 rpm
A rotation rate of 1 revolution per minute (1 rpm) is generally considered optimal for minimizing motion sickness among inhabitants in a space colony. This rotation speed provides a sense of gravity through centripetal force, allowing people to walk around and perform daily activities without experiencing significant discomfort or motion-related issues. Faster rotation rates, such as 2 rpm, 3 rpm, or 4 rpm, can lead to increased feelings of disorientation and motion sickness due to the higher angular velocity, potentially impacting the well-being and productivity of the residents.
Therefore, to ensure the comfort and well-being of the inhabitants in a space colony, a rotation rate of 1 rpm is preferred.
