A fascination throughout centuries of astronomy, navigation,
and astrology is to ground ourselves with space and time.
Celestial spheres are merely the beginning of my search for
gravity.
"The first question concerning the Celestial Bodies is whether
there be a system, that is, whether the world or universe compose
together one globe, with a center, or whether the particular
globes of earth and stars be scattered dispersedly, each on its
own roots, without any system or common center."
-Francis Bacon, 'Novum Organum', 1620
The celestial sphere is an imaginary sphere surrounding the
earth from an observer on earth. All the objects in the observer's
sky can be thought of as projected upon the inside surface of the
celestial sphere allowing them to plot positions of objects in the sky.
"The whole universe is a mystery. Humans have come up with
systems, diagrams and classifications in an attempt to grasp the
infinity within logic and comprehension. Also, to make sense of the
celestial sphere composed of stars, men (and women) throughout
history have grouped them up into constellations constructing a map
layered with mythology and meaning. Despite the disparity of dimension,
our lives can be relected like a universe; vast, wide,
composed of somewhat a system all in the process of discovery,
yet still mysterious with many areas hidden, waiting to be revealed and chanced upon."
