Is truth relative?

[Darkstar]

Yes, but only in the sense that 'truth' is simply a value of 'true' given to a claim. If I say one plus one equals two, this is only true if we are referring to mathematics as we know them. If someone had a different version of mathematics, it might not be true under those circumstances. Or if in another language 'one' meant seven, then it would also not be 'true'.

However, I don't think this is what you're getting at. As for different frames of objective reality, I really can't comment.
