Time is always the most mysterious thing in this universe, more mysterious than space.
Space is a definite existence, visible, tangible, and perceivable.
But time is something everyone knows about, yet it always remains within the realm of knowing.
It is a concept.
Since ancient times, humans have speculated from countless angles about what time truly is.
Some say that time is the rising and setting of the sun.
Some say that time is the blooming and withering of flowers.
Others say that time is a long river, and the universe is a leaf boat in this river.
Einstein devoted his life to trying to reinterpret time with his theories, even attempting to depict the change of time in the way Newton analyzed the change of force. Einstein established a theoretical system at the time that could not be falsified and thus formed a series of serious social cognitions about time.
But in the Elliptical Star System named Ancient Disk, time is an absolute value, indestructible and unchanging.
