The minimum radius of a space habitat needed to maintain <1/100g variation is approximately 100 meters. This is based on calculations of centrifugal force and gravitational acceleration.
The larger the radius of a space habitat, the lower the <1/100g variation will be. This is because a larger radius allows for a greater distance between the center of rotation and the surface, resulting in a smaller difference in gravitational force.
The primary factors that contribute to <1/100g variation in a space habitat are the radius of the habitat, the rotational speed, and the distribution of mass within the habitat. Other factors such as external gravitational forces and structural stability can also play a role.
No, it is not possible to completely eliminate <1/100g variation in a space habitat. However, by carefully considering and optimizing the factors mentioned above, it is possible to minimize the variation to a negligible level.
Yes, <1/100g variation can have negative effects on human health if it is too high. Prolonged exposure to significant variations in gravitational force can lead to muscle atrophy, bone loss, and other health issues. Therefore, it is important to carefully design and maintain a space habitat to minimize <1/100g variation for the well-being of its inhabitants.
