== Definition ==

The Celestial Sphere is anything above the [[troposphere]].

In the Einsteinian Theory of Relativity, the earth can be though of as a point of reference.

== Introduction ==
This point of reference is used in basic physics to simplify calculations, and provides results which are accurate enough to use in [[kinetic projectile modelling]]. The art of [[throw]]ing [[stuff]] at other stuff relies on the understanding that the celestial sphere was created on [[day]] [[four]], and that the [[star]]s can be used to measure [[latitude]] and [[longitude]]. When [[gyroscopes]] are employed in the stabilization of moving objects, greater accuracy can be achieved. The combination of gyroscopes and [[stellar navigation]] is used in [[aircraft]] flight, and in [[rocket science]].

== Use of the Celestial Sphere as a Frame of Reference ==
The use of the stars as a relatively slow system lets the celestial sphere tell us how much the [[spectrum]] from hot [[hydrogen]] and [[helium]] has shifted from the norm in [[electromagnetic frequency]].
