The gravitational interaction of cosmic bodies obeys the third Newton’s law. The force of the light pressure is proportional to the radiation power of the first body, the cross-sectional area and the reflectance of the second body. The forces of light pressure in two bodies will obviously be equal if they have the same given parameters.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
