Q: Are true things really true or is it true that truth is truly just a figment of our imagination because we can not discern truth from lies or is lying just the truth somewhere in the realm of quantum mechanics or maybe just our minds because for all we know the reality we live in, this world, this existence we perceive as "true" might just be untrue. is this true?
