Hello everyone, I'm new to this sector of the Gould's Belt, so let me introduce myself :I go by the name of Santural,the resident of...ok I'll stop being such a dork . Well, I recently read ("studied") The G theory of R, and one thing failed to penetrate the walls of stupidity into my tiny drop of intelligence. What I can't seem to understand, is the application of time as a fourth dimension. How exactly does one measure time? Is it all simply relative? Ex. You can measure time relative to earth, but is there a cosmological "time" that applies to everything? Do forgive me if I'm being a complete dolt, but try to understand my position... Also, as a random thing, isn't the scale of the solar system something amazing, what with the Oort cloud and stuff? Well, sorry for taking your time, Santural.
