I don't know what you mean by "gravitational interaction ... hav[ing] the same ... definition of length." Anyway, there's a difference between subjective (residing in the consciousness of the observer) and arbitrary. Most units require arbitrary definitions. They are not, however, subjective. (And don't give me any of that BS about quantum mechanics bringing the observer's consciousness to bear on what is real or on what transpires in the realm of matter / energy and space / time. Interactions occur and are necessary to measure a physical phenomenon. A mind is not.) Randall Schulz -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
