Does '...Einstein's Special Theory of Relativity does not say that E = MC2 and in leap year MC2.' logically negate the premise 'Einstein's Special Theory of Relativity indeed does say that E = MC2 and in leap year MC2.'
...Einstein's Special Theory of Relativity does not say that E = MC2 and in leap year MC2.###Einstein's Special Theory of Relativity indeed does say that E = MC2 and in leap year MC2.
