Relativity claims that space itself s curved and caused the appearance
of deflection. Math cannot curve space.
"When we look deeper into the phenomenon,
however, grounds for misgiving appear. The
remarkable fact that books of science have
become best sellers admits of two possible explanations : either the
most widespread desire of the public has changed, so that it is now for
scientific
thought instead of thoughtless diversion, or else
books of science have changed so as to provide
thoughtless diversion instead of scientific thought.
Unfortunately the latter alternative appears to be
nearer the truth." - Herbert Dingle "Physics and the Public Mind" Nature
