Why does human knowledge lack perfection in comparison to Ilm-e-Sabiq?
Experimentation is the intrinsic nature of all worldly knowledge due to the fact that it lacks the comprehensive view of what has happened in the past and what may happen in the future. Experiments provide insight into cause-and-effect by demonstrating what outcomes occur when a factor is manipulated.
Ilm-e-Sabiq is based on the premise of fully known cause and effect and foreknowledge of the outcomes.
Most airplane inventors in the early 20th century time were impulsive and disorganized; they would think of an idea, build a plane as quickly as they could, and then try to fly it as soon as possible. Some people tried strapping wings to their arms. Other inventors created planes that looked like giant bouncing umbrellas. As you can probably guess, most of these planes crashed immediately. The inventors would carry home their broken plane, having no idea why it didn't work.
The Wright brothers were much more scientific and methodical inventors. They believed in testing their ideas in smaller or safer versions before building an actual plane. Scientists today, like the Wright brothers, don't just build things and see what happens; they make observations, then form a hypothesis or guess, and then do more tests to see if their hypothesis is correct.
Allah Ta'ala with his divine wisdom, has placed the Sun at an optimum location from the Earth. This results in the Earth's temperature being neither too hot nor too cold, due to which Earth has a favorable environment for the origin, growth and survival of various life forms. On the contrary, if the heat received from insolation (exposure to Sun's rays) increases or decreases by about 10 percent, then Earth would become unsuitable for living organisms.
