Units of Time

Time is comprised of units of increasing and decreasing values.

A unit of time refers to the absolute or observed value of a given time interval.

Although values for time may be observed in relation to other events, the events themselves and their respective intervals have absolute time values which correspond to their changing states.

A planet, star, or galaxy evolves independently of any observation of it, and its lifespan has a time value which corresponds to the changing conditions that determine its evolution. And the same body may be compared to any other object or event, relative to its changing states.

The absolute minimum increment of time corresponds to the minimum quantity of energy required to cause a change in a system.

Theoretically, the smallest increment of time that can occur before the energy is diminished within that time is about 10 to-the-minus 42 seconds.

The largest unit of time is the distance that light travels from the optical limit of the universe to the observer. The optical limit is the farthest distance from which signals traveling at the speed of light can be received.

The largest unit of time is about 10 to-the 39 atomic units, which is said to be equivalent to the present age of the universe.

Standard units of time range from intervals given by atomic frequencies which occur on the order of billionths of a second, to astronomical cycles which occur on the order of billions of years.

The sum of all the subsets of all the unit values of time in the universe never increases or decreases, but remains the same.
