The word kun can be called an extra special imperative word. So IRRSTC thinks, in light of modern cosmological standard model theory
Kun This extra special word has deep significance and deserves scientific analysis.
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.[1] Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimeters (0.67 in). Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges
Definition
Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation. (b) Auditory sensation evoked by the oscillation described in (a)."[4] Sound can be viewed as a wave motion in air or other elastic media. In this case, sound is a stimulus. Sound can also be viewed as an excitation of the hearing mechanism that results in the perception of sound. In this case, sound is a sensation.
Physics
Sound can propagate through a medium such as air, water and solids as longitudinal waves and also as a transverse wave in solids. The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. The sound source creates vibrations in the surrounding medium.
Waves
Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves (in solids) are waves of alternating shear stress at right angle to the direction of propagation.
Sound waves may be viewed using parabolic mirrors and objects that produce sound.[8]
The energy carried by an oscillating sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter, and the kinetic energy of the displacement velocity of particles of the medium.
Speed
The speed of sound depends on the medium the waves pass through, and is a fundamental property of the material. The first significant effort towards measurement of the speed of sound was made by Isaac Newton. He believed the speed of sound in a particular substance was equal to the square root of the pressure acting on it divided by its density:
c = p ρ . {\displaystyle c={\sqrt {\frac {p}{\rho }}}.}
Sound pressure level
Sound pressure is the difference, in a given medium, between average local pressure and the pressure in the sound wave. A square of this difference (i.e., a square of the deviation from the equilibrium pressure) is usually averaged over time and/or space, and a square root of this average provides a root mean square (RMS) value.

C0smology and Modern Science
How did the universe come about?
How did the universe come about? This is a basic question of common people. The answer to this question was sought over the ancient Greek scientists-philosophers named Democritus, Aristotle, Socrates, Jaber Ibn Hayan Al Arabi of the Middle East in the Middle Ages, Sir Isaac Newton in the analog era in the seventeenth century, Rutherford in the nineteenth century, Albert Einstein, Max Planck, Heisenberg, Edwin Hubble in the digital era of the twentieth century were able to know and report the state of creation of the universe after Big Bang , even before its creation i.e., Bing Bang till its next state, and only one question lies in getting a good answer, at least to reach the ultimate truth of the material structure of the universe which was the main mission and vision of progress of science.
It should be noted that in 1964, after finding the remnants of cosmic cosmological background radiation, scientists can find out how the universe came about through computer simulations of radiation obtained. The answer to this question was: The universe came into being through the Big Bang.
According to American astrophysicist Carl Sagan, the truth lies in enlightening answers to bold questions. One such bold question was: What was the nature of the universe before the Big Bang? The answer that can also be found in the modern cosmological standard model theory is: the highest energetic radiation in which the Big Bang caused the creation of billions of billions of galaxies including the sky and earth, satellites, stars, Milky Way or galaxies.
IRRSTC believes that a bold question becomes inevitable as we reach deeper into the universe, namely, was the Big Bang event of the highest energetic radiation a mere accident or an event?
According to scientists, the universe is structured in two layers. 1) Visible 2) Invisible. Visibility: Scientists claim that humans can see billions of light years in space with the naked eye. When a substance is crushed, it is possible to see microscopic particles of maximum 10-17 cm in size in super digital microscope. Scientists have not been able to see the outer material particles. Because of this, scientists believe that the string theory of 10-33 magnitudes is still nothing more than a fantasy. Of course, the IRRSTC believes that string theory was proven in 2012 with the discovery of the Higgs boson particle.
Another cosmological question that remains relevant is, by what source is the universe being ordered? Commentary of the modern cosmological standard model theory in this context: 4 major forces exist in the nature of the world respectively 1. Electromagnetic force, 2. Weak nuclear force 3. Strong nuclear force and 4. The gravitational force was unified before—and even after—the Big Bang.
The question is where were the four great powers in the beginning? In this context the IRRSTC holds that the four great forces were initially concentrated in the Highest Energetic Radiation.
Next question: What is the source of Highest Energetic Radiation? However, we do not know whether such questions exist in physics.
It should be noted that there is a proverb in the world of science to the effect that there are questions in the universe whose answers are not supposed to be found in this world. But science does not guarantee answers to all questions. Therefore, IRRSTC thinks that the answer to the question regarding the origin of Highest Energetic Radiation may not be found in modern science. However, according to astrophysicist Carl Sagan, to fully understand the universe requires bold questions.
Soil
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from soil by restricting the former term specifically to displaced soil.
Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution).[1][2]
Composition
A typical soil is about 50% solids (45% mineral and 5% organic matter), and 50% voids (or pores) of which half is occupied by water and half by gas.[32] The percent soil mineral and organic content can be treated as a constant (in the short term), while the percent soil water and gas content is considered highly variable whereby a rise in one is simultaneously balanced by a reduction in the other.[33] The pore space allows for the infiltration and movement of air and water, both of which are critical for life existing in soil.[34] Compaction, a common problem with soils, reduces this space, preventing air and water from reaching plant roots and soil organisms.[35]
Physical properties
The physical properties of soils, in order of decreasing importance for ecosystem services such as crop production, are texture, structure, bulk density, porosity, consistency, temperature, colour and resistivity.[58] Soil texture is determined by the relative proportion of the three kinds of soil mineral particles, called soil separates: sand, silt, and clay. At the next larger scale, soil structures called peds or more commonly soil aggregates are created from the soil separates when iron oxides, carbonates, clay, silica and humus, coat particles and cause them to adhere into larger, relatively stable secondary structures.[59] Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction.[60] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining. Resistivity refers to the resistance to conduction of electric currents and affects the rate of corrosion of metal and concrete structures which are buried in soil.[61] These properties vary through the depth of a soil profile, i.e. through soil horizons. Most of these properties determine the aeration of the soil and the ability of water to infiltrate and to be held within the soil.[62]
Soil moisture
Soil water content can be measured as volume or weight. Soil moisture levels, in order of decreasing water content, are saturation, field capacity, wilting point, air dry, and oven dry. Field capacity describes a drained wet soil at the point water content reaches equilibrium with gravity. Irrigating soil above field capacity risks percolation losses. Wilting point describes the dry limit for growing plants. During growing season, soil moisture is unaffected by functional groups or specie richness.[63]
Available water capacity is the amount of water held in a soil profile available to plants. As water content drops, plants have to work against increasing forces of adhesion and sorptivity to withdraw water. Irrigation scheduling avoids moisture stress by replenishing depleted water before stress is induced.[64][65]
https://en.wikipedia.org/wiki/Soil
Accordingly, soil is a three-state system of solids, liquids, and gases.[3] Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time.[4] It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion.[5] Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem.[6]
Most soils have a dry bulk density (density of soil taking into account voids when dry) between 1.1 and 1.6 g/cm3, though the soil particle density is much higher, in the range of 2.6 to 2.7 g/cm3.[7] Little of the soil of planet Earth is older than the Pleistocene and none is older than the Cenozoic,[8] although fossilized soils are preserved from as far back as the Archean.[9]
Collectively the Earth's body of soil is called the pedosphere. The pedosphere interfaces with the lithosphere, the hydrosphere, the atmosphere, and the biosphere.[10] Soil has four important functions:
as a medium for plant growth
as a means of water storage, supply and purification
as a modifier of Earth's atmosphere
as a habitat for organisms
