Further more: yes absolutely your hand would […]
Does gravity affect aging?
Does gravity affect aging? There is no correlation between Gravity and aging. Aging is a process that is independent of Gravity. Gravity is a property of matter. Has more to do with atmospheric pressure than the effects of Gravity. Is gravity necessary for life? Gravity is very important to us. We could not live on […]
