Roberts Roberts your analysis of Einstein's 1911 equation c'=c(1+V/
c^2) is so silly and contradictory that I suspect you are just
experimenting with some new ad hoc camouflage. Perhaps 10 years ago
the experiment would have been more successful but now.....Look around
you Roberts Roberts - you are the only hypnotist in Einstein criminal
cult that still defends Einstein's idiocies. Even hypnotists as silly
as Steve Carlip and John Baez now know what is going on and do not
wish to take their heads out of the sand (lately you have not seen
messages from them defending or even mentioning Einstein's relativity
have you).
