What is Polymorphism
Polymorphism in materials science is the skill of a solid material to exist in more than one form or crystal structure. Polymorphism can potentially be found in any crystalline material containing polymers, minerals, and metals, and is related to allotropy, which refers to elemental solids. Together with polymorphism the complete morphology of a material is explained by other variables like crystal habit, amorphous fraction or Crystallographic defects. Polymorphism is relevant to the fields of pharmaceuticals, agrochemicals, pigments, dyestuffs, foods, and explosives.

Arago spot (D.F.J. Arago) A bright spot which appears in the shadow of a uniform disc being backlit through monochromatic light emanating from a point source.
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
As CPH is a boson, does it has structure? Answer; a CPH is tiny energy and it is not a boson. When a CPH takes spin, then it converts to graviton.
