That's the truth.  By definition, a definition has to have a frame of
reference.  (Gahh, that's twisted. (8-) )  Thus, there is no universal
frame of reference.

However, you can choose things so that your frame of references is as
large as possible.

That's really not a problem, because as soon as you define your base
measurement, you can build a consistent measurement system on top of
that e.g. going from grams (or pounds, if you insist (8-) ) to ton(nes).
And it works in a large scale, in that a hydrogen atom is going to be a
hydrogen atom anywhere in the Universe (assuming a) you buy the theory
that laws of physics are wide scale, and b) you ignore nasty things like
singularities.)

Use the Cesium clock standard - one TimeJerry is the amount of required
for my reference material to vibrate x times (where x is a very large
number).

Then you can tackle the distance problem really easy.  One DistanceJerry
is the distance light covers in one TimeJerry.

You can however express energy as E=mv^2, or mgh, or other ways that
avoid this problem.

Wasn't this brought up in 'Contact?'  (I'm thinking of the book, not
the movie.)  Measurements can be handled as long as you can somehow let
the other people know what frame of reference you're using.  (The idea
of Voyager and the 12 Quasars comes to mind, if my memory is at all
working...)

And as long as you establish the vocabulary, you can express the actual
definition of things like democracy, freedom, and ownership.  (Granted,
the actual implications may be beyond communication; but, on the flip
side,
we have problems discussing it amongst ourselves.)

I should throw in a disclaimer that I was trained as an Applied
Mathematician, so I believe most things in the Universe are open to
measurement and analysis through mathematics.

Apologies for the rambling (gotta love the midnight shift...)
