“The Conservations Laws” maybe? -
Conservation Laws
Quote"If a system does not interact with its environment in any way, then certain mechanical properties of the system cannot change. They are sometimes called "constants of the motion". These quantities are said to be "conserved" and the conservation laws which result can be considered to be the most fundamental principles of mechanics. In mechanics, examples of conserved quantities are energy, momentum, and angular momentum. The conservation laws are exact for an
isolated system.
Stated here as principles of mechanics, these conservation laws have far-reaching implications as symmetries of nature which we do not see violated. They serve as a strong constraint on any theory in any branch of science.
Conservation Laws"
Unquote.
So, the verities of nature in the above passage, from article linked by one are:
Without interaction from the environment, external forces, a thing cannot change.
So "change" is a verity of nature.
Similarly "not to change" is another verity of nature, if there are are no external forces.
These are opposite to one another, yet realities in nature.
Kindly correct me, if I am wrong? Please
Anybody, please
Any other verities of nature, please
