Conditions under which a world of straight lines exists

I thought it was a straight line, but it was actually a curve.

In reality,

• friction

• heat

• noise

• External disturbance

It gets in there. In other words, nature is always slightly curvilinear .

● Twist position (3D straight line)

● A world where the shortest distance is not a straight line

Relationships become more complex when the space changes.

Straight lines represent "shape," while curves represent "relationships."
