Of course we cannot know what cannot be known, but we can know some kinds of things which cannot be known. I suggested a couple in post #113. We cannot know things which are just not available to us to know. We cannot know factually any detail of the universe beyond a certain distance, because the light from those parts of the universe has not reached us yet. We can conjecture and make intelligent guesses what it might be like in general, but cannot know the detail.
It has nothing to do with feeling.

Good point, Hank. Yet I suppose eventually more will be "seen" as more of the universe is "lit up" when the light from what is the present Hubble horizon eventually gets here. Maybe not by you or me, but by some future generation. So the question isn't really answerable as a flat-out negative, as far as we know.

Questions like this don't have much to do with "feeling."
