Tid er et mål for FORANDRING i et system. Uden forandringer ingen
fornuftig mulighed for definition af begrebet og størrelsen 'TID'.
I øvrigt: Uden forandringer ingen processer og dermed intet liv.
Hermed, på engelsk, et lille indlæg om spørgsmålet: Hvad er tid? (Og
om forøgelsen af størrelsen Entropi)

TIME IS CHANGE. THE QUANTUM OF TIME. THE INCREASING ENTROPY.
By Louis Nielsen Treatise:

About the concept of 'time' there are many questions:
What is 'time'? How should we define the concept of 'time'? How can
the physical quantity 'time' be defined? Is 'time' quantized? Is
'time' connected to matter? Is 'time' connected to the evolution of
the Universe?
My considerations about 'time' are the following:
The quantity 'time' is a measure, which we humans with our brains and
intellect have introduced in order to measure CHANGES in physical
systems.
A priori 'time' is non-existing in the Universe. I disagree with
Emmanuel Kant (1724-1804) who claimed that 'time' and 'space' has a
priori existence.
'Time' is an a posteriori quantity, i.e. a quantity based on our
experience that we observe changes in Nature. Because processes are
discontinuous this implies that the time quantity must be defined as a
quantized quantity. Space and matter are also quantized.
THE QUANTUM-EVOLUTION OF THE UNIVERSE.
My definition of 'time' is based on the quantum-evolution of the
Universe. In my "Quantum Cosmology" the quantum-evolution of the
Universe is a consequence of the creation of more and more fundamental
energy-/matter quanta that are spreading out in a growing Universe.
The reproduced quanta, which I call Unitons, are the 'buildingblocks'
of all matter and they are responsible for all interactions. The
Unitons - the true atoms - are the smallest and most fundamental
energy-/matter quanta in the Universe.
When the Universe came into existence it consisted of only ONE quantum
of matter, called by me 'The Cosmic Embryoton'. 'The Cosmic Embryoton'
had an extension which define 'the quantum of space', that is the
smallest physical volume.
Gradually, 'The Cosmic Embryoton' disintegrated into more and more
fluctuating Unitons. The created Unitons had been spread out in an
expanding Universe.
The quantum-evolution of the Universe can be described by a 'Cosmic
Evolution Quantum Number' 'ticking' up through the natural numbers,
beginning with the number one when the Universe came into existence.
The actual value of the 'Cosmic Evolution Quantum Number' is equal to
the actual total number of Unitons.
In our epoch the 'Cosmic Evolution Quantum Number' has the very large
value of about 7*10^(127).
In our epoch the Universe therefore consists of about 7*10^(127)
Unitons which is equal to 7*10^(127) 'cosmic quantum changes' of the
evolved Universe. (Se more about equations and calculations in my
treatise)
THE QUANTUM OF TIME.
The 'Quantum of Time' corresponds to the smallest physically 'Quantum
of Change'.
But what is the smallest 'quantum of change' or the smallest 'quantum
process'?
According to the 'Uniton Creation Theory' (you can study more in my
treatise) the 'smallest' and most fundamental quantum process is the
creation of one more Uniton in the Universe.
Every cosmic quantum 'jump' of the Universe is a result of the
creation of ONE MORE UNITON. The creation-process of one more Uniton
defines the 'smallest physical quantum-process'.
This cosmic 'quantum of change' can give us the definition of the
'smallest physical quantum of time', 'the time-atom'.
The progress of cosmic quantized time corresponds to the creation of
more and more Unitons in the Universe. This can also give us an
understanding of the cosmic increase of the quantity called
'Entropy'.
THE COSMIC DIGITAL CLOCK.
The actual age of the Universe is thus proportional to the actual
total number of Unitons in the Universe. We can thus define the value
of THE INVARIANT, ABSOLUTE, AND DISCRETE COSMIC TIME, the age of the
Universe, to be proportional to the actual number of Unitons in the
Universe.
Measurement of 'the cosmic time' is thus - in principle - a counting
of the discrete increasing of the number of Unitons.
The direction of time - the arrow of time - is in the direction where
the number of Unitons in the Universe is increasing.
The cosmic entropy is increasing because the number of Unitons is
increasing!
