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 ?
Absolutely true! That no physicist has ever seen an electron but its existence is proved by large number of experiments and observation in various physical phenomenon like photoelectric effect, flow of current due to electrons, structure of atom consisting of protons, electrons consisting of quarks. But there is hardly any evidence for the existence of “ghosts”. Nothing in this universe proves the existence of the ghosts, not even single experimental observation/trial. Hence, these two statements are totally different from each other. Final Answer The given two statements are entirely different from each other.
