The problem of time has been fascinating thinkers since ancient times. Many philosophers, such as Plato, Aristotle, Kant, and scientists like Sir Isaac Newton, Albert Einstein have tried to conceptualize and analyze time in many ways. According to Albert Einstein, time is an illusion, and it exists to keep everything from happening at once.

There are two main recognized concepts about time: the physical time which is objective, and psychological time which is subjective and has a mind-dependent existence. A more radical third concept is- does time really exist?

In the Theravada, the Buddhist holy book, the idea that time does not exist, independently, is quite significant. Although many thinkers were interested in investigating the concept of time, only some agree that time's existence depends on the mind.

To comprehend the concept of the non-existence of time, let us assume that there is no moon and the Earth does not rotate on its axis, i.e., there is no sunrise or sunset, only perpetual days on one side (facing the sun), and nights on the other side (opposite to the sun) of the Earth. Life evolved in a thin area between the day-night sides. Sapiens of this hypothecated world would never be capable of developing the idea of time. For them, time bears no meaning.

This section is about time, non-conclusive, but exploring different concepts, including- ‘Time’ as another fundamental force of nature that rips apart the universe from the point of its singularity, and still pushing the universe to expand.
