The emission theory says "yes" but this is not essential: it can be shown that the Michelson-Morley and Pound-Rebka experiments rigorously prove the validity of the two equations, without any reference to the emission theory. The problem is that for the moment Einstein zombie world does not give a shit about what experiments prove and what they don't prove. Pentcho Valev pvalev@yahoo.com
