== 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]].

 The '''Celestial Sphere''' is the view of the sky, from Earth. Because the human eye cannot perceive the distance away from Earth, the Sun, Moon, stars, and planets all appear as if they are on a giant sphere centered at the Earth.
