There seem to be all kinds of trivial examples of absolutes, especially mathematical and logical ones...at least when given a specific set of axioms. Now, does the fact that we can change the axioms and get different results mean that absolutes don't exist? I wouldn't think so, since you can absolutely determine the result from a given set of axioms.
Why even go into "absolutes" in physics and whatnot? I think they probably exist, but I don't know what they are, but how is it useful to debate such a topic? It doesn't change the way the world works, and its obvious that we don't know that much about how it does work, anyway.
As for "magick", my theory on that is that it works along the same energy that prayer does, which, in essence, is a Will determining some kind of change in the physical world. Again, there's no a-priori reason why there has to be any absolutes invoved in this or not, but I think there probably are.
