The path to reaching the truth is not unique.
This is also what mathematics itself tells Wang Qi.
In the eyes of the general public, space is flat. For them, Euclidean geometry is the naturally occurring geometry of this material world.
But in reality, there are no "straight lines" in nature. The traces of artificial craftsmanship in the concept of "straight line" are no less than those in "arc" and "hyperbola." And Euclidean geometry is not naturally occurring either. It merely simulates nature, simulating space based on human perception.
If there were an intelligent species whose primary sense was completely different from that of humans, their concepts in geometry would also be completely different from humans.
