I dont see the point. The earth is approximately spherical no matter who or where you are. if it looks flat form one perspective it is not because it is flat, its because it looks that way.
The obvious example is it didn't look spherical to the authors of the Bible (amongst other ancient men), who's perception of the World was confined to ANE which IS essentially FLAT terrain; hence they conceived of a flat Earth, and God didn't tell them any different. Hence the 'inspired' Bible speaks of the round Earth with a dome-shaped firmament over it; it's also why there's many midrashim with rabbis discussing the same scriptures, thus amplifying that they too conceived of the Earth to be flat.
(It's interesting to contemplate what might've happened if the authors of the Bible lived on any of the few places on Earth where the curvature CAN be discerned with the naked eye from atop a tall mountain overlooking the ocean, observable due to the curvature of the ocean on the horizon.)
SBF: If we take other dimensions into consideration then the reality becomes somewhat more complicated than simply an approximate sphere.
how so? you are just trying to use some words you think are impressive and hope we will pretend you got any idea what you are talking about. you dont. if you claim there are other dimensions and accordingly the earth is not round, well, you got to explain yourself.
The first example that popped into MY mind when reading SBF's words is the perception of someone who LACKS stereopsis (3D, AKA depth perception), and hence is unable to perceive depth since they're monocular (their depth cues are only 2D). In their case, their perception is dramatically different than those who possess stereopsis, and a spherical shape will be indiscernable to them from that of a round spape, since they perceive in a different dimension than us (2D than 3D).
Probably better to wait before jumping to conclusions pre-emptively.
Oh, on this:
There is the perspective called reality...
That would be false.
Perspective is NOT reality, but is defined as one's view OF reality that is inherently limited by one's constrained viewpoint, and influenced by how we determine interrelationships and weigh comparative importance. It is one's perception of reality, which actually admits there ARE other weighs to perceive reality that might provide more insight into reality, in order to construct a model useful mental model OF reality.
If anyone's interested in the topic of preception, I'd reccommend taking a course in fundamentals of psychology that touches on models of perception, or even comparative anatomy of perceptive skills, etc.
