Considerations on the subject of chaos

A few phrases at the beginning
…in the beginning was chaos …. from chaos arose order ….. or chaos is the basis for the principle of self-organization which explains the present universe with its complex structures … etc.

Self-organization theory – the reciprocal movements of a complex system controlled by the laws of non-equilibrium thermodynamics. According to this theory, the system can “spontaneously” organize itself if energy flows through it. In other words, if we have energy differences and a chaotic system among them, and we start the energy flow given by energy differences, then the initially chaotic system will start to organize itself into higher orderly predictive complex structures. This is verified many times not only in thermodynamics, physics, but also in chemistry or biology. The proven theory in practice many times. But it adds more questions to the origins of life and the origins of the universe than it explains them. On the one hand, the requirement of an energy differences. Secondly, an impulse triggering the flow of energy. Furthermore, the regulation of the flow of energy and, above all, the origin of energy, or what we call energy.
It is very unpleasant to expect chaos to infinity. See an image below

Chaos everywhere. It doesn’t matter if the chaos of thermal or vacuum fluctuations. There is a contradiction. But what is valid for a finite, however large, number of particles and boundary conditions may not be valid for an infinite number of particles. Especially for indefinable fluctuations of the quantum field. There are already contradictions in chaos that do not cancel out in its application to the infinite, infinite expanse of chaotic behavior – fluctuations, gas molecules, etc. Chaos, chaotic fluctuations cannot be stable, they must move, or they must arise and disappear, there must be mutual collisions, mutual interaction. This is a question of further research, or considerations based on detailed observations on the basis of derived base units. Not to mention the necessary and unquestionable existence of at least two different chaotic environments – the basis of thermodynamics.
The question of what is beyond chaos is meaningless. It doesn’t make sense in the view of derived units from regular appearances modulated on chaotic fluctuations. Just like asking what’s outside the universe. The universe and its internal parts, including the chosen units, behave as they do. There is no external observer, only internal observers with internal relationships. The question of the outside is not a matter of science, but a matter of Faith – and that is another topic.

What is the meaning of chaos? How can chaos exist? Where did chaos come from?

Chaos can´t exist by itself, by its inner power, by its nature. It can´t hold together by its own properties. Chaos cannot sustain itself in chaotic behavior. Chaos must be sustained, allowed to behave chaotically. Firstly – to be in motion and secondly to be limited from the outside or inside. Without allowed motion and limiting conditions, the chaotic particles (waves) would collapse in themselves. Or they would have drifted apart indefinitely. Very roughly – See particles of gas. These particles must be in motion and to be limited in closed space or limited by gravitational field. The gas molecules would either collapse into each other or move away from each other.

The gas is defined as the collection of particles (waves) as such exists only in closed space or with gravity forces. Without gravity forces or without closed space there is no gas as we understand it – colliding particles. To stretch the space infinitely – there are no collisions, no gas, no random fluctuations, no chaotic behaviour. Chaos without collisions is not the chaos. Collisions are given by external forces – gravity or closed space like vessels or anything else. We quietly postulate this, but it’s important to think about it in more detail.
Without a closed space or gravity forces, there is not only no gas, but there is no chance to condense into a liquid or solidify into a solid. See phase transitions.
Chaotic behaviour needs bounds. Chaos needs boundary conditions. Without bonds, without boundary conditions there is no chaos, no chaotic behaviour.

Two conditions defined the chaotic behaviour of gas
1) the limited space
2) the motion of parts.

The gas need limits – without limits gas could not exist There must be limits for interaction – reciprocal collisions among particles of gas.

It is very difficult, if not impossible, to apply partial knowledge of the classical behaviour of gases to an unlimited number of particles, waves or various fluctuations.

The situation with the chaotic behaviour not only of the gas but also of the quantum fluctuations is similar to the probability calculus. Particles with no external limits would expand to infinity. Thus, there is no chance of at least two particles meeting. Likewise in probability – there must be limits (edges of the dice, sides of the coin, given possibilities, etc.). If there were no limits we cannot evaluate probability. It is hard to calculate the probability of one hard-to-differentiate event out of an infinity of possibilities of hard-to-differentiate events. However, we know that when we look more closely we discover still new details, and likewise when we go the other way, to a great distance – still new and different structures.

How to cancel chaotic behaviour? How to cancel gas properties? Very easy. Put the gas into closed box. After that let´s fly to intergalactic space. Open the box and all chaotic behaviour will be over. Gas will not exist from this moment. But each particles of the gas had some movement? The movement didn´t dissappear. The particles are free to move freely through space, each in the direction it had after leaving the box. At some distance from the box, the particles will occasionally collide, but at multiples of the distance from the box, each particle will fly to its own side without ever colliding with another particle. Until particles reach the nearest galaxy with their stars and planets.
On the other hand we can cancell the chaotic behaviour if we reduced the particle speed to zero then particles would collapse in themselves.

Go on! Imagine only particles in closed box in empty space (without galaxies) – imagine material particles of chaotic gas motion. Every particle has its own mass. Every particle weighs something.  We will open the box and what will happen? The particles are free to move freely through space, each in the direction it had after leaving the box. But we are in the empty space without galaxies. In other words, the particles fly into free space and if their velocity is less than the escape velocity they collide again at the starting point. But the gas will no longer exist. The particles will be motionless together, at most oscillating due to internal atomic motions.

If their velocity is greater than the escape velocity, then the particles will move away to “infinity”. But we already know from inertia and spacetime that the slightest matter deforms spacetime. In short, the free particles will move for a long time through the gently deformed spacetime until they come together again at another place – after many orbits of the curves of the deformed spacetime.

Imagine our universe which is filled by moving particles. Every particle has its own mass. These particles interacts with each other by collisions among them. They are attracted to each other, but they will never be away from each other. The range of their appearance defines the dimension of the universe. It doesn’t have to be just particles, but perhaps the basic vacuum fluctuations of the quantum field.

Let’s try the following suggestion – in the beginning of the universe there was no chaos. In the beginning there were primordial origins of boundary conditions. The result of boundary conditions is the chaotic behaviour of everything inside the boundary conditions. Not mention wildly „bubbling“ quantum fluctuations.
It is impossible for ours (humans) to explain the subject of primordial origins of bounding conditions (gravity, closed space) by derived thermodynamical equations describing behaviour of bounded chaotic gas which depends on upper mentioned bounding conditions.

If the chaos can´t support itself then the chaos is unable to form itself to higher structures. Especially organized organism. The flow of energy through chaos doesn´t solve anything. See self-organization theory. We need chaos, resp. at least two different chaotic environments with the difference of an energy levels, after that there are some germs of organized structures.

Go back to thermodynamics – the well-known thermodynamic equation for the chaotic behaviour of an ideal gas for a given pressure, temperature and volume, the equation pV = nRT  needs at least two different chaotic closed space with the ideal gas, it doesn´t matter if the closed space is the universe, the atmosphere of the Earth or closed vessel or a cylinder with a piston inside that.

For thermodynamics we need at least two different chaotic environments. One of which is closed. See a closed volume of gas in the atmosphere. Two differently chaotic environments in terms of the intensity of chaos. Only then does thermodynamics begin with its equations. As in physics or mathematics, we must have at least two different dimensions or values – distance, volume, area, force, speed, time, intensity, voltage, etc. Then we can compare, measure and solve. Then we can generalize and predict and verify by measurement, etc.

To have energy we must have at least two or more wavelenghts. Only one wavelenght there is no ratio – only one value equals to 1 (or anything else as we wish). The value of energy is given by ratio of measured energy to base unit for energy. 

Conservation of energy (matter) is valid only for isolated space like in second law of thermodynamics. The sum of total energy before the experiment in isolated space is equal with the sum of total energy after the experiment.

The law of conservation energy or of conservation shapes or structures like pots or artworks at all. The law of conservation of information? The question is the category of space – open, closed or isolated space. There could be a change in the category of space in the universe. 

Not only the law of conservation energy, but conservation of frequency or shapes, space, volume or artworks which are sometimes broken? Where is the point of view? What about the frequency. What does the frequency mean? Regular changes or nearly regular changes? See probabilistic distribution with peak in the middle. How long the frequency must to be or how many? Where is the point of view for valuating what is frequency, how many are there parts and so on. What about the part of frequency? Like the part of the pot which is created by the potter. Such laws are valid only for isolated space. And what does it mean the isolated space? Is it even possible to have that kind of space in the universe?

Where did the information come from? Where did all “regular” changes come from in such indescribable random cirmcumastances of quantum foam. new music songs, art works, inventions, new ideas, etc. The law of conservation of new music songs, art works, inventions, new ideas, etc.  information? See entropy – informations, shapes and structures.

See thermodynamics
There are a large number of equations of state for real gases. These equations become more complicated the higher the accuracy required and the wider the range of pressures and temperatures we want to describe and the closer the real gas state is to the critical point. 

In the beginning we have chaos – the gases expand as they want, one more, one less, each time differently – at first sight we have no chance to describe the behaviour of the gases.

A few scientists (Boyle, Mariott, Gay, Lussac, Pascal, Torriceli, … ) start to take a closer look at the behavior of the gases. They enclose the gases in containers with a piston, measure (using their chosen units of temperature) what has changed (temperature, pressure, volume), isolate the gases from their surroundings and behold very simple elementary math formulas come out.

 pV = nRT where p-pressure, V-volume, T-temperature, R-gas constant

After next time, we find when we go into detail that the calculated values differ. Let’s refine our equations with more measurements. We get more complex formulas – not so simple.

van der Waals

not mentioned constant a, b.
And if we go into even more detail – we have a choice – very complex formulas with a certain accuracy for a given region of physical conditions we obtain the BWR equation (Benedict, Webb and Rubin)

In the beginning there is a chaos of the gases behaviour. In the first time there is a pretty simple and beautiful equation for ideal gases. In the middle there is quite complicated but also beauty equation. In the end there is an chaos of very complicated equation which are valid for very narrow range of pressures and temperatures. There is again a chaos, but in descriptiveness. See a curve below.

chaos            equations      over-describe,

In summary: The more the equation describing the physical process is more general the more beautiful such equation is and vice versa the more concrete equation is the more its beauty decreases. Thus, beautiful equations have a wide range of validity with poor accuracy and less beautiful equations have a very limited range of validity with high accuracy. The simple thermodynamic equation of state is not applicable in practice. Respectively it is applicable, but as a very inaccurate view and even for light gases such as hydrogen, helium. When using the Van der Waals equation, the situation is better. Furthermore, we use specialized equations with a defined interval of their validity. Example from practice – calculation of a circuited hot water network (not mention a circuited steam network) – even if we use the best equations, as accurately as possible, if we specify the appropriate water values for the given conditions – we still get only frame results. And the hot water network has to be finely regulated in practice.
In other words – without measurement and control, technical processes are not possible in practice. Just by equations we can set a given range, but without external regulatory interventions the function of hot water systems, steam power plants, rockets and in general all technical infrastructure is impossible. In the same way it is impossible to accurately predict the behaviour of billiars balls after n-collisions. Not to mention legendary three body problem formulated by H. Poincare
This is what makes the engineering interesting. The situation is different every time, even if the calculations show the same results. You still need to respond differently. There’s always something to discover, like in science. There are always new adventures of experience until Infinity.
Summary: Thermodynamic processes served in their time as the basis for the derivation not only of entropy, but of all considerations of energy and, in fact, of the behaviour of the whole universe. When the basis is the same, it is hard to believe that the description of the thermodynamics of a collapsing star, or processes in dust nebulae, processes in star-gas systems, etc., that these processes will proceed ideally according to framework calculations as opposed to difficult (mostly iterative) calculations of the motion of three bodies, or processes in steam systems, or in the production of artificial diamonds, etc. It is hardly possible to predict the future evolution of the universe on the basis of idealized quantum mechanical equations together with the equations of general relativity. And vice versa to accurately document the history of the universe up to now.

The very interesting thermodynamic process – isothermal expansion of an ideal gas

At the beginning of such process there is the ideal gas with its characteristics as temperature T, pressure P , volume V, energy U, number of particles N, density D, entropy S. We will examine this process in detail in terms of the base units – the definition of distance (volume), pressure and temperature. At the beginning of the isothermal expansion there is an initial state with following values of T1, P1, V1, U1, N1, D1, S1

in the end of the isothermal expansion there is a final state with following values of T2, P2, V2, U2, N2, D2, S2

T1 = T2, P1 > P2, V1 < V2, U1 = U2, N1 = N2, D1 > D2, S1 < S2. The temperature is constant as well as the internal energy and numbering of particles, of course. The pressure after expansion decreased, as well as the density, which are both connected. On the contrary, the volume has increased along with the entropy, which are both again connected. The internal energy of expanding gas – it is constant. Throughout the isothermal process, the reduction of internal energy is compensated by the supply of thermal energy from the outside. Which means that 100% of the supplied external thermal energy is converted into mechanical work. The chaotic behavior of the ideal gas molecules is converted into a directed movement of the piston in a given direction, with the efficiency of 100 %. At first it looks amazing, but we need to go further. See pressure reduction together with volume increase, Thus a change in the ordering of the possible states of the gas molecules – the entropy. The adiabatic expansion also converts the internal energy of the chaotic ideal gas into useful work of the directed piston motion. But not with 100% efficiency. Then, if there were to be 100% efficiency, the internal energy of the gas would have to drop to 0 – in short, the gas temperature would have to be 0 Kelvin – which is impossible.

It is good to remind and discuss the experiment with the compression or expansion of electromagnetic radiation enclosed in a box (mirrors, for example). The so-called Einstein experiment. When the box is compressed, the wavelength of e.g. light is reduced, so the frequency f is increased, which means an increase of energy E = hf. The increase of the energy of the enclosed radiation is at the expense of the work supplied from the outside in compressing the box.

It is good to remind and discuss the experiment with the compression or expansion of electromagnetic radiation enclosed in a box (mirrors, for example). The so-called Einstein experiment. When the box is compressed, the wavelength of e.g. light is reduced, so the frequency f is increased, which means an increase of its energy E = h*f, where h is Planck´constant. The increase of the energy of the enclosed radiation is at the expense of the work supplied from the outside in compressing the box. See below an initial state wit enclosed wavelenght with initial energy E1 = h*f1

after expansion the wavelenght in the closed box will be longer, there will bel longer wavelenght with lower frequency which means lower energy E2 = h*f2 – see below

This makes it very easy to demonstrate isothermal and adiabatic expansion of radiation. In adiabatic radiation expansion, the situation is simple – the wavelength becomes longer, the frequency and thus the energy becomes lower. The longer the wavelength expansion, the greater the efficiency. 100% efficiency is unreachable – the wavelength would have to be extended to infinity, i.e. the frequency would be reduced to zero.
But the situation is different in the case of isothermal expansion. Here the wavelength and therefore the energy remains constant. Space is becoming longer, but the wavelength is still constant. Which is possible if the decrease in frequency (wavelength expansion) is supplied from the outside so that the frequency and hence the wavelength remains constant. But that’s a contradiction in terms. For the wavelength of radiation to remain the same at a given extension, it means moving the piston of the enclosed space a distance equal to the wavelength. So there will be two wavelengths in the enclosed space. Or three, or four, … or x, depending on how many wavelength periods there were to begin with. See below – initial state for expansion

In the inital state there are four periods f1 of radiation oscillation. There are two courses of thermal expansion – adiabatic or isothermal.

Firstly the adiabatic expansion. The final state for the adiabatic expansion – see below

After the end of adiabatic expansion there are again four periods, but with longer wavelength and lower frequency h2. The difference in energy E1before and after E2 the expansion is equal to the work A done by the piston. A = E1 – E2 = hf1 – hf2 = h (f1-f2). Part of the radiation energy was used for the work A done by the piston. The longer the path of the expanding piston under the pressure of the radiation, the lower the energy (frequency) of the radiation enclosed in the cylinder. It sounds logical. But go on to the isothermal expansion of radiation.

The final state for the isothermal expansion – see below

We see that there has been the addition from four to six of periods. Somewhere from the outside. Thus, the enclosed frequency remains constant. What about the work done by the piston? The radiation energy in the cylinder is constant, there is no reduction. The energy is still equal to E = hf. What work A did the piston make during a move of a distance of two periods? The energy E of radiation is constant! 

By the way. Imagine a moving ball in the same closed space – the cylinder with the piston inside that. Such ball has kinetic energy Ek. If it is an adiabatic expansion, the kinetic energy Ek of the ball is reduced at the cost of the work A done by the piston. If it is an isothermal expansion, then the kinetic energy Ek of the ball remains constant – because it is kept on the same level by supply the energy Es from the outside. Es = A. There is a decrease in the kinetic energy of the ball, but its energy is restored to its original amount from the outside. The velocity of the ball will be the same after the isothermal expansion. It is the same with the isothermal expansion of radiation. As the radiation expands, its energy decreases. It depends on the piston displacement. That’s the work done by the piston. But the frequency of the enclosed radiation is from the outside returned to its original level – before the expansion. 

Go back to isothermal expansion of enclosed radiation. It is interesting that the change of the piston position in the case of isothermal expansion takes place in steps equal to the wavelength of the enclosed radiation. Or the piston may move by distances equal to multiples of the wavelength of the enclosed radiation. The piston has allowed states, allowed positions, allowed distances. In the case of an intermediate position is not an isothermal expansion. See allowed positions of electron orbitals.
There is a prolongation of the enclosed radiation during the isothermal expansion. The frequency is constant during the “jump” or quantum expansion, but there are many more wavelengths, which leads us to another interesting question about expansion or changes in spacetime in general. 

Let´s imagin the following thinking experiment. No adiabatic expansion, but adiabatic compression of radiation in closed box. To adiabatically compress radiation from outside then we need to supply the work dA. The energy of radiation inccrease to dE = h*df = dA. That’s fine, the change in frequency and therefore the energy of the radiation is equal to the work dA supplied. But suppose we want to compress the radiation to a wavelength close to zero, i.e. the frequency and hence the energy will increase towards infinity. How to do that? Where to find in the world, in the universe, a force so powerful? It is most likely to be found in a collapsing very massive star where the thermonuclear reaction stops and there is nothing to balance the gravitational force.  Since we are on a thought experiment, there will be an empty space inside the collapsar filled with enclosed radiation. See below

A collapsing massive star goes into the neutron star stage. And the enclosed radiation must be compressed with enormous force. But what is the strength of the gravitational field inside the star? Maximal or minimal? The intensity in the center of such star is exactly equal to zero. The radiation inside such a massive star, a neutron star, is gravitationally isolated from the neutron star. See below the intensity K and potential U of the gravitational field inside and near a very massive ball. 

Why do I write down these articles, these reflections? Because the above gravitational intensity and potential profiles are derived from idealized models where we assume a continuous gravitational force. Infinitesimal calculus – differential equations. But gravity cannot be continuous – it does have its bearers. That bearers are grouped atoms, or then particles (neutrons) at close distances. The grouped excitations of the quantum field. But what do we know about such tight excitations? Are they even possible from our perspective of sparse densities compared to the density of a neutron star? Or how does the quantum field behave in such a massive star? However, this massive star, even if it collapses, is the result of a quantum field. Does that mean the quantum field is collapsing as well? Would the effect be stronger than the cause? We don´t know the origin of quantum excitations so-called waves-particles.

But go on! When the collapsing star begins to approach the black star stage (called a black hole) the energy of the compressed radiation will be greater than the energy of the star itself, and on further compression the enclosed radiation will have such a short wavelength – almost infinitesimal – that its energy will be greater than the energy of our entire universe. See below

All we need to do is fit the upper equations mathematically. Not to mention the energy of the collapsing star. By the way, time slows down dramatically in the immediate surroundings of a neutron star. So a star, if we respect general relativity, cannot, in the time of our universe, collapse into a black hole. From our point of view, the collapse “freezes”.

Gravity needs space. Just like every field excitation, just like every property needs space. Without space, there is neither matter nor time. Just as time does not exist outside of matter and space.
Thus, it is at most likely that a collapsing star will return to its initial state – the basic fluctuating excitations of an omnipresent quantum field. But verification is beyond our limits.
