It is a gutter level physics. Any way, a single postulate of constancy of c has opened flood gates of irrational, idiotic and illogical stream of statements. Even a school child, if rational and honest will say that if c is absolute then it is different in different frames. If it is frame dependent, then it is not absolute. |
