Many Talmudic sources themselves, interpreters and commentators seek to reconcile contradicting opinions by steering each opinion off to a different scope/topic.
Someone gave an example of a cylinder, that one can see it as a circle from above or as a square from the side. But then factually they are both wrong, failing to see its depth and likening it to a two-dimensional form.
A good example for such a Machlokes is in Gittin 6b:
"א"ל ח"ו ומי איכא ספיקא קמי שמיא א"ל אלו ואלו דברי אלהים חיים הן זבוב מצא ולא הקפיד נימא מצא והקפיד: אמר רב יהודה זבוב בקערה ונימא באותו מקום זבוב מאיסותא ונימא סכנתא איכא דאמרי אידי ואידי בקערה זבוב אונסא ונימא פשיעותא
So the "absolute truth" that G-d gives is that in reality there were two reasons for the incident, however, R Yonatan saw only one and so R' Evyatar. Evidently they both didn't know/consider the other option.
Why seeing only one aspect of a problem can be considered "truth"?
NB: this question is only for Machlokos that are explained in such a way, and not for those where two opinions clash with no resolution.
