Death is a Spiritual Promotion
If planets neglect exercising and stop moving, their heat will decrease. Therefore, they will be deprived of this form of life, and just like the human body, they will turn into other forms. If the human body gets cold and loses its heat due to complete stagnation or other factors, human beings will reach spiritual promotion and turn into other forms. However, they will not diminish, as nothingness does not hold any meaning in the infinite universe, and substances never diminish, because there is no way to turn them into nothingness. Wherever they go, or wherever they are forced to go, they still ARE, albeit in other forms. After spiritual promotion, substances from the body of a human, an animal, or a planet still exist in another form different from their regular and previous state of life.
