If objective directional orientation (forward, right, left, etc.) objectively exist in an observer-independent way, then would inverting Flat Land cause Four-Eyed Freddy to notice a difference?
From our external transcendental perspective in our 3D/4D world, the difference between the two below images is merely that they have been inverted horizontally. But that means that all the internal relationships in the 2D world have been preserved.
If Flat Land Four-Eyed Freddy can't notice a difference, does that mean that there is no objective difference, meaning reductio ad absurdum
we have proven that objective observer-independent directional orientation does not exist in relativistic physics?
In any case, if you disagree with any of the below statements, please specify which ones are the ones with which you disagree and which ones are the ones with which you agree:
1. Directional orientation (e.g. fowardness, leftness, rightness) is
2. Directional orientation (e.g. fowardness, leftness, rightness) is not
3. Directional orientation (e.g. fowardness, leftness, rightness) is not
4. Two observers can disagree about directional orientation (e.g. fowardness, leftness, rightness) and neither is more correct than the other.
5. Directional orientation (e.g. fowardness, leftness, rightness) is not
6. Even if we specify the 4-sided box as the reference place, it is impossible to objectively say whether the blue car is on the right or left.
7. Even if we specify the center of the 4-sided box as the reference point, it is impossible to objectively say whether the blue car is on the right or the left.
8. It is impossible to specify which car is on the right or left without creating (i.e. making up) a reference frame.
9. If we put into the image certain kinds of asymmetrical creatures, namely a human, we could infer the reference frame that creature/human would tend to use. For instance, we could infer based on our knowledge of humans that a human would tend to treat itself as the stationary center of the universe and treat its eyes and nose as pointing forward, thereby making up a directional orientation (i.e. reference frame) relative to itself based on its own asymmetries and its own labels for its own body-parts (e.g. what it calls one eye versus the other or one hand versus the other). Thus, if different humans were looking in different directions, they would tend to each disagree about which way was forward because they each tend to make up a reference frame based on the premise of themselves being the center of the universe with their eyes looking forward.
