Harrov pondered for a long time before reluctantly accepting the fact that a perfect circle does not exist, then continued to inquire, "I understand your first point, but what about the second?"

"The second point is the interference of the gravitational forces of other planets. Even if the orbit of the planet beneath our feet initially approximated a perfect circle, after millions of years of evolution under the gravitational influence of other celestial bodies, deviation is bound to occur," Lynn explained.

"I see!" Harrov suddenly realized, enlightened that gravity exists among all things and must naturally interfere with each other. Even if this interference is minimal, over the span of millions of years, it would be amplified enough to influence the orbits of the celestial bodies.

There was a third influencing factor that Lynn did not mention, which was that the stars themselves are not stationary. They too move around the center of the galaxy, so disturbance is inevitable.
