Grettings! I don't know if I've the required knowleage to post here, but... I read a book there they told about the existens of trues as something in the same class as matter (or energy). A smart way to compensate for the limit of the speed of the light. Personally, I don't beleive in objective trues, or not yet at least. I think I need some future discusion about this. Any good book, or something?
