Molecules of two elements, nitrogen and oxygen, comprise about 99 percent of the air. The remaining hoity toity 1% includes small amounts celestial seasoning luxurious riches as argon and carbon dioxide. (Other gases such as neon, helium, and methane are present in trace amounts.) Oxygen is the life-giving element in the air.

Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles.

Even when the air seems to be completely clear, it is full of atmospheric particles - invisible solid and semisolid bits of matter, including dust, smoke, pollen, spores, bacteria and viruses. Some atmospheric particles are so large that you will feel them if they strike you. However, particles this large rarely travel far before they fall to the ground. Finer particles may be carried many miles before settling during a lull in the wind, while still tinier specks may remain suspended in the air indefinitely. The finest particles are jostled this way and that by moving air molecules and drift with the slightest currents. Only rain and snow can wash them out of the atmosphere. These tiny particles are so small that scientists measure their dimensions in microns - a micron is about one 25-thousandth of an inch. They include pollen grains, whose diameters are sometimes less than 25 microns; bacteria, which range from about 2 to 30 microns across; individual virus particles, measuring a very small fraction of a micron; and carbon smoke particles, which may be as tiny as two hundredths of a micron.

Particles are frequently found in concentrations of more than a million per cubic inch of air. A human being's daily intake of air is about 450,000 cubic inches. This means that we inhale an astronomical numbers of foreign bodies. Particles larger than about 5 microns are generally filtered from the air in the nasal passages. Other large particles are caught by hairlike protuberances in the air passages leading to the lungs and are swept back toward the mouth. Most of the extremely fine particles that do reach the lungs are exhaled again - although some of this matter is deposited in the minute air sacs within the lungs. From these air sacs, particles may go into solution and pass through the lung walls into the bloodstream. If the material is toxic, harmful reactions may occur when it enters the blood. Fine particles retained in the lungs can cause permanent tissue damage, as with Coal workers' pneumoconiosis (black lung disease), caused by buildup of coal dust in the lungs, and with silicosis, which is caused by the buildup of silicon dust.

If the air is still, given sufficient time, all but the smallest airborne particles will settle to the ground under their own weight. Their rate of fall is closely proportional to particle size and density.
For example, vast amounts of fine volcanic ash were thrown into the air by the eruption of the Indonesian volcano Krakatoa, in 1883, and again by the Alaskan volcano Katmai, in 1912. In both instances, the finer dust reached the stratosphere and spread around the world high above the rains and storms that tend to cleanse the lower atmosphere. In fact, many years elapsed before these volcanic dusts entirely disappeared from the atmosphere. Since a two-micron dust particle may require about four years to fall 17 miles in the atmosphere, the lingering effect is not in the least surprising.
Dust storms are also prolific producers of airborne debris. Europe is sometimes showered with dust originating in the Sahara. In March 1901, for instance, an estimated total of two million tons of Sahara dust fell on North Africa and the Europe. Two years later, in February 1903, Britain received a deposit estimated at ten million tons. On many occasions, Sahara dust has fallen in muddy rain and reddish snow over much of southwestern Europe. During North America's droughts of the 1930s, dust storms blew ten million tons of dust at a time aloft in the heart of the continent. Occasionally, high winds swept the dust eastward 1800 miles to darken skies along the continent's Atlantic coast.

When the wind strikes the crest of an ocean wave, or a calm sea is agitated by rain or by air bubbles bursting at the surface, the finer droplets that enter the air quickly evaporate, leaving tiny salt crystals suspended in the air. Winds carry these salt crystals over all the Earth. Normally, airborne salt particles from the sea are less than a micron in diameter. It would take a million of them to weigh a pound.
Salt particles play an important part in weather processes because they are hygroscopic - they absorb water. Raindrops usually form around tiny particles that act as nuclei for condensation. Generally, each fog and cloud droplet also collects around a particle of some type at its center. Tiny crystals of sea salt make better condensation nuclei than other natural particles found in the air. Thus, salt particles in the air help make rain.

Dust from meteor showers may occasionally affect world rainfall. When the Earth encounters a swarm of meteors, those meteors that get to the upper reaches of the Earth's atmosphere are vaporized by heat from friction. The resulting debris is a fine smoke or powder. This fine dust then floats down into the cloud system of the lower atmosphere, where it can readily serve as nuclei around which ice crystals or raindrops can form. Increases in world rainfall come about a month after the Earth encounters meteor systems in space. The delay of a month allows sufficient time for the meteoric dust to fall through the upper atmosphere. Occasionally, large meteors leave visible trains of dust. Most often their trails disappear rapidly, but in a few witnessed cases a wake of dust has remained visible for an hour or so.
In one extreme instance-a great meteor that broke up in the sky over Siberia in 1908-the dust cloud traveled all the way around the world before it dissipated.

Large forest fires are among the more spectacular producers of foreign particles in the atmosphere.
Because these fires create violent updrafts, smoke particles are carried to great heights, and, being small, are spread over vast distances by high altitude winds. In the autumn of 1950, forest fires in Alberta, Canada produced smoke that drifted east over North America on the prevailing wind and crossed the North Atlantic, reaching Britain and continental Europe. The light-scattering properties of this dense smoke made the Sun look indigo and the Moon blue to observers in Scotland and other northern lands.

Wind-pollinated plants are the most prolific sources of foreign particles in the air. This is a problem for people with allergies.

Spores are closely related to pollens. Spores are the reproductive bodies of fungi, which include molds, yeasts, rusts, mildews, puffballs and mushrooms. Tiny spores are adrift everywhere in the air, even over the oceans. Although they resemble pollens in general appearance, spores are not fertilizing agents. Instead, they are like seeds, and give rise to new organisms wherever they take hold. Spores have been found as high as 14 miles in the air over the entire globe. Most fungi depend on the wind for spore dissemination. Once airborne, spores are carried easily by the slightest air currents.

Once, physicians were taught that infectious microorganisms quickly settle out of the air and die. Today, the droplets ejected, say, by a sneeze, are known to evaporate almost immediately, leaving whatever microorganisms they contain to drift through the air. Only a relatively small fraction of microorganism’s human beings breathe cause disease. In fact, most bacteria are actually helpful. Some, for example, convert atmospheric nitrogen into usable plant food. Pathogenic, or disease-producing, microorganisms, however, can be very dangerous. Most propagate by subdivision-each living cell splits into two cells. Each of the new cells then grows and divides again into two more cells. Provided with ideal conditions, populations multiply quickly. Fortunately microorganisms do not thrive very well in the air. Unless there is enough humidity in the air, many desiccate and die. Short exposure to the ultraviolet radiation of the Sun also kills most microorganisms. Low temperatures greatly decrease their activity, and elevated temperatures destroy them rapidly. Still, many microorganisms survive in the air, despite these hazards. Among the tiniest of airborne particles are viruses, which are on the borderline between living matter and lifeless chemical substances.

Earth is the only planet we know of that can support life. This is an amazing fact, considering that it is made out of the same matter as other planets in our solar system, was formed at the same time and through the same processes as every other planet, and gets its energy from the sun. To a universal traveler, Earth may seem to be a harmless little planet in the far reaches of one of billions of spiral galaxies in the universe. It has an average size star of average brightness and is joined by seven other planets — which support no known life forms — in its solar system. While this may be fitting for a passage from The Hitchhikers Guide to the Galaxy, by Douglas Adams, in the grand scheme of the universe, it would be a fairly accurate description. However, Earth is a planet teeming with vitality and is home to billions of plants and animals that share a common evolutionary track. How and why did we get here? What processes had to take place for this to happen? And where do we go from here? The fact is, no one has been able to come close to knowing exactly what led to the origins of life, and we may never know. After 5 billion years of Earth’s formation and evolution, the evidence may have been lost. But scientists have made significant progress in understanding what chemical processes that may have led to the origins of life. There are many theories, but most have the same general perspective of how things came to be the way they are. Following is an account of life’s beginnings based on some of the leading research and theories related to the subject, and of course, fossil records dating back as far as 3.5 billion years ago.

The solar system was created from gas clouds and dust that remained from the Sun's formation some 6-7 billion years ago. This material contained only about .2% of the solar system's mass with the Sun holding the rest. Earth began to form over 4.6 billion years ago from the same cloud of gas (mostly hydrogen and helium) and interstellar dust that formed our sun, the rest of the solar system and even our galaxy. In fact, Earth is still forming and cooling from the galactic implosion that created the other stars and planetary systems in our galaxy. This process began about 13.6 billion years ago when the Milky Way Galaxy began to form. As our solar system began to come together, the sun formed within a cloud of dust and gas that continued to shrink in upon itself by its own gravitational forces. This caused it to undergo the fusion process and give off light, heat and other radiation. During this process, the remaining clouds of gas and dust that surrounded the sun began to form into smaller lumps called planetesimals, which eventually formed into the planets we know today.

A large number of small objects, called planetesimals, began to form around the Sun early in the formation of the solar system. These objects were the building blocks for the planets that exist today. The Earth went through a period of catastrophic and intense formation during its earliest beginnings 4.6-4.4 billion years ago. By 3.8 to 4.1 billion years ago, Earth had become a planet with an atmosphere (not like our atmosphere today) and an ocean. This period of Earth’s formation is referred to as the Precambrian Period. The Precambrian is divided into three parts: the Hadean, Archean and Proterozoic Periods.

The Earth formed under so much heat and pressure that it formed as a molten planet. For nearly the first billion years of formation (4.5 to 3.8 billion years ago) — called the Hadean Period (or hellish period) — Earth was bombarded continuously by the remnants of the dust and debris — like asteroids, meteors and comets — until it formed into a solid sphere, pulled into orbit around the sun and began to cool down. Earth's early atmosphere most likely resembled that of Jupiter's atmosphere, which contains hydrogen, helium, methane and ammonia, and is poisonous to humans. (Photo: NASA, from Voyager 1). As Earth began to take solid form, it had no free oxygen in its atmosphere. It was so hot that the water droplets in its atmosphere could not settle to form surface water or ice. Its first atmosphere was also so poisonous, comprised of helium and hydrogen, that nothing would have been able to survive.
Earth’s second atmosphere was formed mostly from the outgassing of such volatile compounds as water vapor, carbon monoxide, methane, ammonia, nitrogen, carbon dioxide, nitrogen, hydrochloric acid and sulfur produced by the constant volcanic eruptions that besieged the Earth. It had no free oxygen. About 4.1 billion years ago, the Earth’s surface — or crust — began to cool and stabilize, creating the solid surface with its rocky terrain. Clouds formed as the Earth began to cool, producing enormous volumes of rainwater that formed the oceans. For the next 1.3 billion years (3.8 to 2.5 billion years ago), the Archean Period, first life began to appear and the world’s land masses began to form. Earth’s initial life forms were bacteria, which could survive in the highly toxic atmosphere that existed during this time. Toward the end of the Archean Period and at the beginning of the Proterozoic Period, about 2.5 billion years ago, oxygen-forming photosynthesis began to occur. The first fossils were a type of blue-green algae that could photosynthesize.

Earth's atmosphere was first supplied by the gasses expelled from the massive volcanic eruptions of the Hadean Era. These gases were so poisonous, and the world was so hot, that nothing could survive. As the planet began to cool, its surface solidified as a rocky terrain, much like Mars' surface (center photo) and the oceans began to form as the water vapor condensed into rain. First life came from the oceans. Some of the most exciting events in Earth’s history and life occurred during this time, which spanned about two billion years until about 550 million years ago. The continents began to form and stabilize, creating the supercontinent Rodinia about 1.2 billion years ago. Although Rodinia is composed of some of the same land fragments as the more popular supercontinent, Pangea, they are two different supercontinents. Pangea formed some 225 million years ago and would evolve into the seven continents we know today. Free oxygen began to build up around the middle of the Proterozoic Period — around 1.8 billion years ago — and made way for the emergence of life as we know it today. This increased oxygen created conditions that would not allow most of the existing life to survive and thus made way for the more oxygen-dependent life forms. By the end of the Proterozoic Period, Earth was well along in its evolutionary processes leading to our current period, the Holocene Period,  or Anthropocene Period, also known as the Age of Man. Thus, about 525 million years ago, the Cambrian Period began. During this period, life “exploded,” developing almost all of the major groups of plants and animals in a relatively short time. It ended with the massive extinction of most of the existing species about 500 million years ago, making room for the future appearance and evolution of new plant and animal species. About 498 million years later — 2.2 million years ago — the first modern human species emerged.

Did You Know? The first modern human being was called **** habilis, the first of the **** genus. This species developed stone tools for use in daily life. **** habilis means “Handy Man.” He existed from about 2.2 to 1.5 million years ago. There are earlier species related to modern man, called hominids. The images show the skull shape and probable appearance of **** habilis.

The PreCambrian Period — accounts for about 90 percent of Earth’s history. It lasted for about four billion years until about 550 million years ago. About 70 percent of the world’s land masses were created in the Archean Era, between 3.8 and 2.5 million years ago. Rodinia, widely recognized as the first supercontinent, formed during the Proterozoic Era, about 2.5 billion years ago. It is believed that the oldest human family member was discovered in Ethiopia and lived 4.4 million years ago. It was named “Ardi,” short for Ardipithecus ramidus.

Dear Poet Friends, I conclude this series on The Enigma of Time by mentioning few important features about the concept of Time according to Modern Philosophy and Science. I have used a
simple format, and also tried my best to simplify the concepts for your kind appreciation. Unfortunately, there is no provision on this Poetry Site to show Diagrams to elucidate! If you like this one, kindly repost the same for wider circulation! Thank you, Raj Nandy, New Delhi.
            
       CONCLUDING THE ENIGMA OF TIME IN VERSE:
                      PART THREE – BY RAJ NANDY
              
              TIME ACCORDING TO MODERN PHILOSOPHY

UNREALITY Of TIME : Mc Taggart’s ‘A’ and ‘B’ Series:
Now skipping through the pages I come to Modern Philosophy, with Mc Taggart the British philosopher of the 20th Century.
He had acquired a substantial following with his 1908 paper on the ‘Unreality of Time’ initially.
With his quibbling argument he states, that moments in his ‘A’ Series of Time are either of past tense, present tense, or of future tense.
It is all about human perception, since we experience the past through our memories;
Become aware of the present through our senses, while future is pretty unknowable.
Here time appears to be flowing through us, as nothing remains stable around us!

In his ‘B’ Series of Time Mc Taggart expresses differences in moments of time as either Before or After,
Without using the tenses used in his ‘A’ Series of Time.
All parts in time can be expressed equally as points along a time line, in the absence of past, present, and future tense;
While here we appear to be flying through time in a metaphorical sense!
Thus in the ‘A series’ time appears to be flowing through us, but in ‘B series’ we seem to be flying through time on a timeline created by us!
Therefore, Mc Taggart finds both the ‘A’ and ‘B’ Series describing Time to be inadequate and also contradictory;
And he finally concludes that Time is unreal and does not exist in reality!

How Mc Taggart’s Theory Was  Updated :
Modern Philosophers have re-casted Mc Taggart’s theory in term of findings of Modern Physics.
His A-Theory is updated into ‘PRESENTISM’, which holds that only thing that is real is the ‘present moment’.
In ‘Presentism’ time has no past or future, and time has no duration either!
All things come into existence and drop out of existence, and past events no longer exist;
And since the future is undefined or merely potential, it too does not exist!

His B-theory is re-formulated into ‘ETERNALISM’ or the ‘Block Universe’, influenced by the later Theory of Relativity.
‘Eternalism’ holds that past events do exist even if we cannot immediately experience them, and future events also exists in a very real way.
The ‘flow of time’ we experience is just an illusion of consciousness.
Since in reality, time is always everywhere in an eternal sense!

Theory of Growing Block Universe:
It was proposed by the Englishman CD Broad in 1923, as an alternative to ‘Presentism’ where only the present exist;
And also as an alternative to ‘Eternalism’ where past, present, and future together also exist.
In ‘Growing Block Universe’ only the past and the present exist, but not the future.
Since the growing of the block happens in the present, with a very thin slice of space-time continuously coming into existence;  
Where consciousness as well as the flow of time are not active within the past,  
But they can occur only at the boundary of this ‘Growing Block Universe’!
Few scholars this concept did criticise, saying that in this theory the word ‘now’ can no longer be used to define Time!

But according to Einstein, this perception of ‘now’ that appears to move along a timeline, creating the illusion of ‘flow of time’, arises purely as a result of human consciousness;
And the way our brains are wired due to our evolutionary process, enabling us to deal with the world around us in a practical sense.
“People like us, who believe in Physics, know that the duration between the past, present, and the future is only a stubbornly persistent illusion,’’ said Einstein.

A poem on ‘The Paradox of Time’:
Now to lighten up my Reader’s mind, I present only the first three stanzas from ‘’The Paradox of Time’’, composed by the British poet Austin Dobson:
  “Time goes, you say? Ah no!
   Alas, Time stays, we go;
      Or else, were this not so,
  What need to chain the hours,
  For youth were always ours?

  Ours is the eye’s deceit
  Of men whose flying feet
     Lead through some landscape low;
  We pass, and think we see
  The earth’s fixed surface flee,
     Alas, time stays, we go!

  Once in the days of old
  Your locks were curling gold,
     And mine had shamed the crow.
  Now, in the self-same stage,
  We’ve reached the silver age,
  Time goes, you say? - ah no!
       Alas, time stays, we go!”
            
HOW LIGHT IS CONNECTED WITH THE CONCEPT OF TIME:
Brief Background:
I commence with quotes from the ‘Book of Genesis’ - Chapter One, along with my thoughts about Light and Time,
Before concluding this series with Albert Einstein’s concept of Space-Time.

“And God said, “Let there be light,” and there was light. God saw that the light was good, and he separated the light from the darkness. God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day. ……And God said, “Let there be lights in the vault of the sky to separate the day from the night, and let them serve as signs to mark sacred times, and days and years, and let them be lights in the vault of the sky to give light on the earth. And it was so.”
                                                      - BOOK Of GENESIS Chapter One.

Since ancient days, Light had acquired a religious and a spiritual significance.
Since Light became associated with goodness, intelligence and ultimate realty;
Light accompanies transcendence into Nirvana of Buddhist religious philosophy.
In due course the Sun began to be worshipped as an important live-giving deity.
As seen in the symbolic form of Egyptian Sun God Ra, and the Greek gods Helios and Hyperion as the Sun god and god of Light respectively.
In Hindu mythology Surya is the Sun god, and Ushas the goddess of Light.
Huitzilopochti, both the Sun god and god of War of the Ancient Aztecs was kept pleased with human sacrifice!

SOME PROPERTIES OF LIGHT:
Plato, during the 5th Century BC said that God was unable to make the World eternal, so gave it Time,  - “as the moving image of eternity.”
While some seven hundred years later St. Augustine in his ‘Confessions’ said,
That when God created the universe out of darkness with light, “the world was also created with Time, and not in time.”
Thus along with light, time also began to flow, while our scientists discovered a connection between the speed of light and time, few centuries ago!
To understand this connection between light and time, we must first understand something about the properties of light.
Light is the visible part of the electromagnetic spectrum* which can be perceived by our human eye.         (See Notes Below)
As seen in the red, orange, yellow, green, blue, indigo, and violet colors of the Rainbow in the sky,
When water droplets acting like countless prisms break up white sunlight!
Now this electromagnetic spectrum also contains the ultra violet and infra red spectrum which our eyes cannot see.
But this entire electromagnetic spectrum contains Photons, which are discreet packets of zero mass less energy.
In a vacuum light photons travel at 186,000 miles for second, which Einstein declared as the cosmic speed limit, and as an universal constant.
When a photon strikes the eye, it is turned into electrical energy that is transmitted to the brain to form an image which we call sight.

NOTES : Gama-rays, X-rays, Ultraviolet lights, have shorter wave lengths & more energy than Visible light. But Infrared, Microwave, Radio waves, with larger wave lengths are less energetic than the Visible spectrum of light. Sir Isaac Newton using a prism had discovered the spectrum of visible light, & used the word ‘spectrum’ for the first time in his book ‘Optick’ in 1671.

EINSTEIN'S SPECIAL THEORY OF RELATIVITY 1905 :
In his Special Theory of Relativity of 1905, he stated that nothing can move faster than speed of light which is 186,000 miles per second.
This speed of light always remains the same, irrespective of its source and frame of reference.
Now the mass of an object would double if it travels at 90% of light’s speed.
But if the speed of light is reached, mass of an object would become infinite!
Since photons, the quantum particles that make up light have a zero mass, they move at the speed of light.
Even inside the World’s Largest Particle Collider (LDC), located near the French-Swiss Border,
Experiments are carried out only around 99.99% of Light’s speed, in accordance with the Laws of Physics.
Einstein had also shown mathematically that on reaching Light’s speed, Time will come to a standstill!
And should this Light’s speed be exceeded, then Time would start to travel backwards, which becomes a mind boggling concept!
Here we enter into the realm of science fiction, which has been described by HG Wells  in his popular novel ‘The Time Machine’.
But to become a time traveler shall always remain our cherished desire and dream!

NOTES: Only mass less particles like the photon can travel at light speed, photons experience no time, they do not age. Objects with mass cannot reach the speed of light since in that case its mass will become infinite. Also, one cannot see the fourth dimension because of Lorenz Contraction, which is also related to stopping of time, for at the speed of light an object will shrink to zero length! Also, particles interact with the Higgs' Field present all around to pick up mass, excepting photons which do not interact with this Higgs' Field.

Now Einstein’s theory of 1905 is called ‘Special’, because it explains how space and time are linked for objects that are moving in a straight line at a greater speed but which is constant.
Time moves relative to the observer, and objects in motion experience ‘Time Dilation’.
Meaning, time moves slowly when it is in motion, as compared to one who is standing still, -  a relative comparison.
This can be further explained by the ‘Twin Paradox’, where a 15 year old travelling in a spaceship at 99.5% speed of light for a period of 5 years,
Returns back to Earth to find himself to be only 20 years old.
But to his surprise he finds, his twin brother on Earth who was left behind, has reached the ripe age of 65 !

Limitations of Special Theory of Relativity:
It was confined to non-accelerating bodies only, and after ten years of deliberation,
Einstein added gravitational force field, space-time curvature, and acceleration, -
To formulate his General Theory of Relativity with satisfaction.

   SPACE-TIME & GENERAL THEORY OF RELATIVITY 1916 :
Isaac Newton during the 17th Century spoke about 'absolute time' and 'absolute space', accordance to the understanding of science of his Classical Age.
Space was the arena where the drama of the universe was played out, and this arena was passive, eternal, and unchanging no doubt.
Time too was absolute with an independent existence, and continued to beat independently like the heart beat of Space!
Newton also gave us the Laws of Motion, and Gravity, with more massive objects exerting more Gravity than a less massive one in reality.
Now one aspect of Special Relativity is that space and time are merged into a four-dimensional space-time entity,
They do not exist as separately as envisaged by Newton and Descartes during the 17th Century.
Some 250 years later Albert Einstein, defined Gravity as a curvature of Space-time.
Einstein also tells us that gravity can bend light, which travels along the curvature of this space-time.
Gravity is flexible, it could stretch like a fabric warping of space-time caused by objects present within it, in fact Gravity is the shape of space-time itself!
The Moon rolls around the curvature created in space-time fabric by the heavier object the Earth,
Just like the massive Sun which creates the depression and curvature around it for the planets of our solar system to orbit round the Sun. *
Einstein’s space-time has been likened to a stretched out vast rubber sheet,
Where heavier the planet, more depression it creates on the fabric of space-time along with its own gravitational field.
Einstein’s Space is not passive like that of Newton, but has a dynamic presence.
Interwoven with Time, Space tells Matter how to move, while Matter tells Space-Time how to curve - in this dynamic presence!
The constant speed of light at 186,000 miles per second, is just a measure of space of something which travels over time;
But both space and time had to adjust themselves to accommodate the constant speed of light!
Thus space, time, and the speed of light are all unified in the General Theory of Relativity,
We owe all this to Albert Einstein, one of the greatest scientists of our Century.
NOTES: **Planets orbiting the Sun do not fall back into the void of space due to the attraction of gravity, and also due to their individual speed of acceleration maintained in orbit as per Kepler's Second Law of Planetary Motion. Mercury has the fastest orbital speed of 48 km per second, Venus at 35 km per sec , and Earth at 30 km per sec. as their orbital speeds. Planets further from the Sun require lesser orbital speed.

UNFINISHED WORK OF EINSTEIN:
During his later years Einstein was secretly working to find a ‘Theory of Everything’,
Which would ultimately replace the erratic tiny micro world of Quantum Mechanics.
His Theory of General Relativity had dealt with the functions of gravity at the greater macro level of the universe only.
So he hoped to extend this theory to find an all embracing Unified Field Theory.
For at the subatomic quantum level, as the Englishman Thomson discovered in 1897,
The electrons inside an atom at times behaved in an alien fashion and were very unstable!
This world of the subatomic particles is a wondrous world where time becomes chaotic;
Where the position of the electrons cannot be predicted with certainty!
Einstein called this unpredictable and unstable behaviour of electrons as "spooky action at a distance"!
In the ‘double-split experiment’ it was seen, that the light photons behaved both like waves and as particles, -
Even though the speed of light remained constant.

EINSTEIN'S NOBLE PRIZE For PHYSICS AWARDED IN 1921:
Now despite Einstein's dissatisfaction with Quantum Mechanics it is rather ironical,
That the Nobel Prize in Physics was awarded to Einstein for his work on the ‘Photoelectric Effect’ at the Quantum level;
Which for the first time had suggested that Light travelled in Waves and also as Particles ( i.e. as photon)!
This observation led to the development of electron microscope, solar panels, night vision devices, at a later date.
Since his Special and General Theory of Relativity considered as ‘The Pillars of Modern Physics’, was still being examined by the Scientific Community;
And they could be proved and accepted only subsequently.

'STRING THEORY' PROPOSED AS THEORY FOR EVERYTHING:
During the 1970s the proponents of ‘String Theory’ had claimed, They found a Theory of Everything, following Einstein’s quest.
They claimed that micro vibrating open and closed looped strings gave rise to some 36 particles at the subatomic level;
But also required 10 dimensions for this 'String Theory' to operate!
In our Standard Model of Physics we have only 18 particles as on date, therefore due to lack of scientific evidence,
There was no Noble Prize for those ‘String Theory’ proponents!
Efforts are on to find a Unified Theory of Everything, and to understand the mysteries of God’s infinite universe, -
We finite humans have just made a beginning!

Now, to reduce the length of my composition I conclude with a short verse by the famous novelist and poet DH Lawrence, -
Who had shocked Victorian England with his explosive ****** novel “Lady Chatterley’s Lover”,
Which later inspired Hollywood, and a film got made.

               RELATIVITY
“I like relativity and quantum theories
because I don’t understand them,
and they make me feel as if space shifted about like
a swan that can’t settle,
refusing to sit still and be measured;
and as if the atom were an impulsive thing
always changing its mind.”  – DH Lawrence.
