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?
Theorems existing in this world are all based on the fact that electrons do exist in atoms. If the concept of the electron is removed from proven Physics, then there will be a crisis of arguments in the existing theories and anything won’t be enough to correctly explain the theories. Whereas, removing ghosts from the world won’t affect any of the existing concepts.
