Q.5:- No physicist has ever “seen” an electron. Yet, all physicists believe in the existence of electrons. An intelligent but superstitious man advances this analogy to argue that ‘ghosts’ exist even though no one has ‘‘seen’’ one. How will you refute his argument?

 

Answer:



Many phenomena which are based on the assumption of existence of atoms have been theoretically predicted and experimentally verified. These phenomena indirectly establish the existence of atoms. But no such phenomenon has been observed which proves the existence of ghosts or which can be explained on the assumption of ghosts.
