dont judge just for fun

ok so as light strikes on matter it exerts force on it which by even almost 0 amount of weight is increased so when a shadow is casted over it then that increase in weight is lost so you can say that the mass of a shadow is negative :P:P:P

Except a shadow isn't a physical thing. It's a space where a light source is occluded.

 

If light is absorbed by an object rather than reflected, it will add mass through energy. Block the light with shadow and the mass is removed, but it wasn't because the shadow had negative mass.

 

Limited analogy: It's more like a canopy that keeps the rain from adding mass to objects below it. The canopy doesn't have negative mass, it just keeps extra mass from accumulating on the objects.
