While I share with you the conclusion that beauty can not be quantified, since beauty is a quality and not a quantity, I disagree that beauty is subjective or relative.

If beauty is subjective, then we can not say that there is anything that is beautiful, since it depends only on the observer, right?

How is it possible then that we can reach an agreement among many people that there is something beautiful and something that is not beautiful?

From my point of view, we can only reach such an agreement if there is an object, not the woman but beauty, because if there were no such object, and beauty were truly subjective, then different subjects should not see such an object that does not exist objectively.

Then you see, beauty is objective, although we can sometimes differ in what is beautiful and what not, we can both agree that we consider things as beautiful, therefore, we know that beauty exists and that it is objective, and the differences that we can have between what is beautiful and what not for us will not be more than opinions, opinions are subjective, therefore, beauty exists and is objective, while what we consider beautiful is subjective.

Finally, relativity has nothing to do with this matter.
