Almost :). I believe it's Hiezenberg's Uncertainty Priniciple (and even
the
I may have spelled his name wrong). Actually, as I remember, you can't
measure the amount of energy an electron of itself has - the energy
state
of an electron is down to where it's orbiting round an atom and you
measure
the amount of energy it gives off when it changes orbits in the form of
EM
radiation. These *are* (as far as I remember) universally constant. And
a I
think it's Occam's Razor, which is the 'if it quacks like a duck and
walks
like a duck' one.

You can't. But there *are* certain things which are apparently to us
actually constant. Two examples would be the speed of light (which stays
constant in the normal universe) and the ratio of a circle's radius to
it's
circumference. Whether this allows you to communicate effectively with
an
alien species is a separate issue. In terms of the FT universe and
measurement you can have a standard measure of time - there are various
ways to do it like atomic decay rates etc. But if you have FTL comms you
can just have a universal speaking clock :). That's presuming you have
FTL
travel. If you only have very very near light speed ravel then your tim
is
up the kaibish too. ( I am presuming whatever FTL system you use doesn't
suffer from relativistic effects). even then, some of the newer
'possibly
FTL' particle effects (like spin reversion) COULD be used to make for
standard time measurement regardless of distance.
