Nature has proven that perfectly straight lines do not exist in reality, despite them being considered the shortest distance between two points. While our world is filled with objects that appear to have directness, such as light rays, crystals, and webs, the concept of perfect directness remains purely theoretical.
For instance, light is believed to travel in straight lines, but in truth, it can be subject to distortion. Diffration causes rays to be slightly cut off, and the curved space-time alters their trajectory. This explains why images of stars captured by telescopes like Hubble or James Webb appear as radiant “Asters” rather than round points. Light can also be refracted in gravitational fields, leading to distorted galaxies.
Crystals, which are natural structures with perfectly straight geometric shapes, also experience imperfections in their lattice structure due to various factors such as temperature changes and radiation. These defects make the edges of crystals slightly uneven, despite their theoretical precision.
Even with human technologies, achieving absolute accuracy proves to be impossible. The most advanced production methods still leave microscopic deviations that are often imperceptible in everyday scenarios.
Ultimately, the ideal straight line only exists in the realm of geometry. In the physical world, everything is susceptible to distortions and defects, rendering true directness an unattainable illusion.
