What if we say the perspective from an object unmoving in the area between our planets is absolute. Something sitting in our galaxy--could space's frame of reference be absolute? Not if there are other galaxies. Like a proof, the term absoluteness implies all aspects are included.

I do not agree with the idea that the earth is the ultimate frame of reference. It is convenient, but it is relative--thus occasionally inaccurate. This means it cannot be absolute, if it is not always correct. For example, if Eric is standing in the physics classroom, and is not moving from the earth's "ultimate" frame of reference, this velocity of zero is true for all perspectives identical to the earth's (such as all standing earth-bound humans). However, he must have some velocity other than zero because he is on earth, which is moving through space. His velocity then is equal to that of the earth's from this perspective. Although it is a small speed relative to those things moving on earth, it is still revolving around the sun. This inequality means that the earth's perspective cannot be absolute.
