People all over the earth have to come across the term "ghost" at some point of their life (probably). Generally it has become a culture that any ordinary layman would believe in ghosts and any scientist would say that "there is no such thing as ghost..and it is a stupid superstition.." Then there arises a question- who among the two is correct? we cannot deny the "eye-witnessed" responses of a layman who believe in religion and all the mythology.. at the same time, we can't deny the words of knowledge of a scientist. If you think that what all the mythology has said about the god and devil is true then, there is a flaw in my above statement..! Is the knowledge acquired by the scientist sufficient to say the ghosts as superstitious beliefs? Is there enough knowledge to study about the ghosts by the way? Ghost and soul phenomenon can have some link with "QUANTUM PHYSICS" (which we have understood not even to an appreciable level) ..or could be any other branch of physics or even a "separate branch" ???
