relativity
the other evening the beautiful and talented alisa and myself were in the back yard looking up at the night sky. it was kinda chilling so we crowded real close to each other to keep warm and let that wonder aura of alisa infuse my being and ... i digress. we were discussing whether jupiter follows the moon across the sky or whether the moon follows jupiter. it's an interesting question because it depends on your point of view and your scale of time. if your sky is just above the heads of the two people at the center of the universe, they see jupiter rise first and set first. the moon is clearly following jupiter. on the other hand, if the sky is the heavens in which the stars live and the planets dance, then jupiter is slowly moving in the direction of the moon. and the moon is moving away from jupiter faster. in this case, jupiter is clearly following the moon.
