text: It seems that every object has its own gravity, or attractiveness to other bodies. Scientists are still puzzled about gravity, but it seems that the larger the mass of an object, the larger the gravity. The further away from the object, the lesser the attractive force.\n\nAlso...human beings and all other animals on Earth evolved to operate effectively in the gravity on the surface of the planet. When we are in less gravity environments or greater gravity environments for extended periods, the body experiences ill effects. For example, in weightlessness, the body loses muscle mass and bone mass. We need our Earth gravity.
