Is anybody out there ---it is the greatest Cosmic Riddle and Paradox.
There could be aliens probably, even advanced ones, but is inconceivable,
that they are incapable of dominating like colonising or remain in apathy
not contacting us. Whereas Elon musk has gone on record to stat,either there are
no aliens or only dead civilizations.This is in conformity with Einsteins special
theory of relativity. The former view based on revised special theory of relativity
of mine, needs unanimous worldwide acceptance , that is the unique possibility and only way to solve the mystery that we are presented with.
