Objectivity is a central philosophical concept which has been variously defined by sources. A proposition is generally considered to be objectively true when its truth conditions are met and are "mind-independent"—that is, not met by the judgment of a conscious entity or subject.
Truth is isomorphic to the reality of the situation.
Correspondence theory says that true beliefs and statements correspond to the actual state of affairs. This appears to say that if a thing is true then it corresponds exactly to the actual state, or condition of the reality in question. Language statements are references through linguistic generalizations , where such generalizations may be interpreted metaphorically as being applicable to many similar situations, things, or objects.
Coherence theory seems to require the holistic approach that differing attributes of the whole system are interrelated and interdependent. the whole is greater than its parts in that dna elementals apply as identity structures in an inclusive set theoretic relationship. In that respect cats are dogs only in that cats are mammals and dogs are mammals but they are not exactly equivalent.
Consensus theory is truth that is agreed upon by many beings in a group situation. consensus truth might not be the actual truth though. Consensus can be dangerous in my opinion, yes.

"Square circles do not exist" is a necessary truth that applies to all possible worlds, if we mean they do not exist in Euclidean 2 dimensional space.

There are some philosophies that say "nothing matters" "life is hopeless" "there is no purpose" etc.
These philosophies cannot be universal as they are highly subjective, and therefore contingent, in character.
