So our luna settler is suffering from hubris when he shows his children 'Earth Rise' ?
No. They are simply using a common but inaccurate expression. They will know that the earth isn't actually rising and will likely have taught their children that.
And the astronomer who says the galaxies are all flying AWAY from us suffers the same hubris?
Do they? They are all moving away from
everything. All astronomers understand this.
No, human centric is just taking note of the OBSERVER EFFECT.
That is not what "The Observer Effect" is. What you are describing is just "being wrong" and it doesn't affect the system being observed.
YOU and the Earth are the center of the universe because you see the heavens wheeling around you.
People of limited knowledge may
think that, but they are wrong.
When you are a train that stops at a station and it feels like it is still moving,
it isn't actually moving, even if it seems like it is.
In each of these far flung stars and planets they see YOU rotating around THEMSELVES.
No hubris needed.
Indeed, just a lack of knowledge, because they are wrong.
The universe isn't rotating around them.
Hopefully this has cleared up your misunderstanding.
