The galaxies are continually moving because they are in a vacume, so there is no friction to slow down and end the movement. Hear on earth any machine conducted as to function in the air, which creates friction and air resitance which slows us down.
P.S why why are you wrighting in capitals?

Galaxies are not in perpetual motion. They're currently spinning out of inertia and their movement away from the galactic center is affected by gravity. If we somehow began tapping into the galaxy's inertial spin, we would slowly but surely reduce it; a true perpetual motion machine would continue to move no matter how much work it did without slowing. However, there is no machinary in the most distantly foreseeable future of humanity capable of harnassing the motion of an entire galaxy, so the question is moot.

Perpetual Motion defined in Wikipedia states:
Perpetual motion refers to a condition in which an object moves forever without being driven by an external source of energy.
http://en.wikipedia.org/wiki/Perpetual_motion
The jury is still out on this one as being able to define the motion of the galaxies through the known universe (e.g., if there was a 'big bang' then there was an origin, hence no pert. motion).
However, if you are referring to the known forces in the universe (i.e., strong electromagnetic attraction, gravity, etc) and as the earth is part of the universe, then those forces are 'at work' on earth. Our dilemma here would be how to overcome those forces in order to be able to do more. They are the limitations which we strive to overcome or in some way circumvent!

There's no need to YELL.
In the vaccum of space, there is negligible friction, so once an object is set in motion, it essentially will never stop.
Wherever you find life, you will find friction, which is the plague of motion. Friction is the doom of perpetual motion.

We do. But gravity can only make things fall so far before they hit Newton on the head.

It's called inertia. Basic physics. Read like...any physic book.

Because we don't know how and you don't know how to spell MACHINERY!!
