It is by design.
That's exactly the point. Theories are not the reality. They are "just" tools to predict the processes we are detecting (Plato's Cave). One thing that I don't understand is, why the fact that gravity can be described by a theory of bended space-time is leading to the assumption, that there really exists such a "rubber cloth" like space. A resonant circuit can be described as a spring-mass like mechanism. But nobody would really assume that there exists little springs inside such a circuit. :-) -- Regards wabe
