1- Flows continuously (changes)
2- It is irreversible
3- It is the reference for speed
4- It is imperceptible, but it can be visualized by means of the parallelochron.
5- It is transcendental (it transcends senses).
6- It is homogeneous. We may perceive an hour of fun different from an hour of work, but the hour lasts the same.
7- Indicates the physical separation between two sequential events. For example, a person at 10 years old is closer to birth than at 20 years.
The present moves away from a point or moment in the past. Another example: In one hour the Sun is placed in two different positions in the sky in relation to the Earth.
P.S:
Philochrony is the natural science that describes the nature of time, proves its existence and teaches us to visualize it.
