Lu Heng attempted to test the rules of the weightless space.
In the end, he discovered that this weightless space was quite peculiar, seemingly not similar to the zero-gravity state of outer space, but rather lacking any gravity, or perhaps with gravity so weak it was negligible.
The gravity felt by humans on Blue Star is composed of two parts: the universal gravitation generated by the mass of Blue Star, and the centrifugal force generated by the rotation of Blue Star.
The reason we feel weightlessness in outer space is that the centrifugal force from orbiting Blue Star and the universal gravitation cancel each other out, resulting in a sensation of floating.
In the weightless space of Zero Civilization, the situation is quite special, and it seems that the cause of the weightlessness is due to universal gravitation being reduced to an insignificant level.
