truth.. is not relative, it is absolute..

I was wondering whether exists a book which would be filled with truth, nothing just truth and so far did not find any. Starting with phylosophy, going trough mechanics till economics.. nothing. At the end what is truth? We can't find truth which would be acceptable for everybody. (that does not mean it can't be truth). I would like to differentiate a little thing here. There is more or less a little gap between truth and fact. Everything what is a fact (e.g. gravity) does not have to be truth in a given statement. We need to work with facts and put them in sentences so we could embrace the truth itself. That's the power of words. Unfortunately so far I've met mainly temporary truths. The sun is beautifuly yellow said my girlfriend. Yeah, it was yellow in 'that' moment, beautifuly?! for whom? Coming to the fact that truth is relative.. But then where we could stand without falling down in the next few decades? Where is the solid ground of absolute truth? One could say we can find the absolute truth in faith (do not blame me I know faith can't be measured in nowadays spectrum), another could say truth is everything what we take into our lifes, life with it, according to that. It is truth for us. It might be changed in time, but in that particular time it is with is, it is absolute. The sun is beautifuly yellow.
