I would say that math is the eternal truth, anywhere and "anywhen".
Having said that, though, it is also quite possible to use the language of math to produce a very convincing lie.
In addition to that, we don't know the language well enough (or physical characteristics it is trying to describe) to always use it. The concepts of infinity or black holes illustrates this as neither is truly describable by any math we know of. This problem can also be seen in Zeno's Paradoxes - the use of "infinitesimals" he was trying to discredit went on to become the precursor to modern calculus, which very neatly explains his paradoxes.
