What is the weight of our shadow

When we move in a partial darkness or on a full moon day, we see our shadow behind us. Do these shadows posses weight. It is unusual to read it, but it is true our shadow too cast some weight which we neglect. Some of you may have some question on how that possible if light is a form of energy having no weight. It is true also the light do not have weight but as they are a form of energy when they travel through air medium they push the particles towards the ground that do possess some weight. Actually higher the mass is, higher it possess shadow having a large area. In the same way the higher is the particles pushed to the ground by the light. Hence they have more weight. According to the different research and investigation made by different scientist they found that the weight of a huge city of the world at the day time is slight higher than they measured at night time. This is the reason that when a air craft is moving the light provides a much energy at its travel. In the same way it is the physical reason that the comets held their tail on the sun.
   In the same way different objects have different weights according to the area they cover. The source of the light that reach on the earth are mainly 3 the one is the sun the second one is the moon and the third one which is visible in the sky and is the bright is venus. It is also the bright source of light. The light that is comming from the venus is highest than the sun as the light from the sun requires the medium while the venus dont. It directly propagate through the vacuum. Hence the light from the vacuum gives more weight than the others does.
     Now we may also have the question if the shadow made up of atoms as it is claimed that every matter in this universe are made up of atoms but as the shadow is the objection of the light blockage so we cannot say or hope that they contian the atom. The light consists of photon that is the particle but having no weight. Thus in this sense we can say that it is without atoms and that actually carries the weight by the particles that they collide and it depends how light is passing. If the light is heavy then dark blck shadow is form in the same way if the light is fade then the weak shadow is form.
