Hmm, but I thought that from a relativistic standpoint we're both moving. Isn't there something about all coordinate systems being equal irrespective of inertial movement? (I know I probably butchered that)

Okay, my understanding of general relativity is pretty basic but... If I sit in a chair on rollers with a bottle of water on a table 2 meters in front of me then spin in a complete revolution in 1 sec, by relativistic principles... The bottle has traveled a distance of 2pi*r, or 12.5 meters around me at a rate of 12.5 meters/sec. Is this correct?
