However, the closest thing we have to understanding an objective absolute truth is mathematics, and even Bertrand Russel showed that human understanding of math is itself limited by contradictory premises (ex-Russel's paradox). To the extent that we "know" that the proven laws of physics accurately explain things, even physicists, such as Steven Hawkins, have noted that other dimensions/universes could exist that are dictaed by entirely different physics.
More than all of this, though, is the fact that we must realize that what we see and know is nothing but the infitessmal perceptions of a human being, that sees only what he/she sees through the faith of our senses. The fact that we see something as red does not mean that that item is in fact red. That we feel something as smooth/hard, cold/warm, only means that this is what we sense. What if there are more important things to sense, and we lack the sensors. To be sure, we don't even know for certain if said item exists, or if anything exists.
All that I know is that I think and therefore I am. That, and that ultimately I am severely limited in what I can know and understand about the universe. Even if, hypothetically, God (or an imaginary all powerful being for those who don't believe in God) opened up all reality and truth to us, and even if, for the sake of argument, our miniscule senses could accurately perceive this truth, it is unlikely that we would be capable of comprehending this truth (at least beyond a very small basis).
