NEWS- Galactic Relation Resolved

BY: Arjit Mishra

Elliptical Galaxies are one of the most abundant type of Galaxies found in the Universe.

Superficially there are four categories to classify Galaxies: Spiral; Barred Spiral; Elliptical and Irregular. 

Elliptical Galaxies have a smooth ellipsoidal morphology, They are mostly found in Galaxy Clusters.

One of the notable feature of an elliptical galaxy is that they naturally contain a much greater proportion of older stars than spiral galaxies do.

Nowadays Astronomers Theorize that most of the elliptical galaxies are formed from the collisions and subsequent  mergers of spiral galaxies. Ages and Complexion of Stellar population holds evidence for this theory, because the stars in elliptical galaxies are much older and redder than those in spiral galaxies. 

Moreover spiral galaxies have abundant gas and dust which eventually fuels Star formation, whilst elliptical galaxies appear to have virtually exhausted that fuel and so there is scarcity of raw material for the formation of new stars. Due to this low rate of star formation and their populations of old, red stars, elliptical galaxies are referred to as 'RED and DEAD' by Astronomers.  

Obviously with the help of Hubble and ESO'S VLT(Very Large Telescope) Astronomers were able to show how star formation in these DEAD- Galaxies actually took place billions of years ago and practically prove the theory.

NEWS- Magnetic Bubble could act as a saviour for Astronauts

By: Arjit Mishra

Human race is trying it's real best to set foot on Mars and other Exoplanets but apart from all the obstructions one of them is that sending astronauts on long-duration missions is kind of impossible because of the hazardous radiation levels in space.

However a new concept offers some hope on the horizon, this Idea takes advantage of the latest advances in superconducting magnet technology to effectively shield spacecraft—and the astronauts inside—from harmful space radiation.

The researchers behind it have received funding from NASA innovative Advanced concepts (NIAC) program to build a prototype called CREW HaT.

HaT stands for Halbach Torus, which is a circular array of magnets that creates a stronger field on one side while reducing the field on other side, They've came up with a design for lightweight, deployable and mechanically supported magnetic coils activated by a new generation of high temperature superconducting tapes.

This configuration produces an enhanced external magnetic field that diverts cosmic radiation particles, but the most interesting thing is that the geometry being proposed creates a magnetic field outside the spacecraft but not inside, so the astronauts are not exposed. The created magnetic field is directly extended out into space it's not bounded within a chamber or something.

Researchers believe that this design can divert over 50 percent of the biology-damaging cosmic rays and higher energy high-Z ions that are responsible for health complications and deaths of astronauts in space. Moreover They still need to reduce the weight and work on the design to make it more efficient.

INDIAN CONCEPTION OF TIME

   By:Arjit Mishra

According to the Vedas of ancient India the basic definition of time reads as- Time is an active potency of the supreme in manipulating the material energy or more lucid definition would be “The means through which matter and energy are connected(during emergence) and separated(during dissolution) is called time”. Since eternity we’ve have known various aspects of macrocosmic definition of time such as- the frame of period from creation of universe to it’s dissolution, and repetitive cycles of such periods, it’s various scalable units and many more things. But only few ones know the microcosmic definition of time or in layman’s language “how time works?” so here is how Vedas describe it- A thought wave that occurs in the mind is termed vritti. For a jiva, time is the space between two successive vrittis. Moreover the screen on which this motion picture of time and space with birth, death, creation and dissolution runs is termed consciousness. Vedas basically tends to merge the concepts of time, space and consciousness and declare that they are all one. In spiritual realm our consciousness is contained in an energy based life form while in the material realm our consciousness is contained in a matter based life form.  Time is an energy which has both spiritual and material aspect, in the spiritual realm time passes but nothing gets older or deteriorated because spirits are not under the jurisdiction of time while in material realm time causes change and is ultimate destructive agency.  

There is one more curious aspect concerning the nature of time, In the vedic system the events are somehow known in advance and this also curiously enough has some relationship with the Theory of relativity. How?

In Einstein’s Theory of relativity time is like a geometrical coordinate which is some sort of space and so events of the future are there in a different region of space. In fact, in Einstein’s theory it is even possible to shift between the dimensions of space and the dimensions of time, so they are sort of interchangeable. Thus everything that is going to happened, everything that is happening and everything that has already happened exist in a sort of timeless domain or are laid out in a continuum. Einstein believed this stuff and quoted “the passage of time is simply an illusion”. He even mentioned human being as a “space-time worm”.

So it turns out that the missing keys of the modern physics are present in Vedas in a very superficial manner.

If Vedas and modern science will work together, a revolutionary development would hit human race very soon.

Delayed Choice Quantum Eraser Experiment

 BY: Arjit Mishra

It is widely said that "efforts in the present decides our future" but what if I say actions in future affects past events! Yes you heard it right. As we aren't able to travel back in time ; it's hard to digest the fact.

But with the help of an experiment in Quantum physics it is possible!(At Quantum level). this experiment is entitled as Delayed Choice Quantum Eraser Experiment, It is basically an extension of Double Slit Experiment.

[NOTE: If you haven't read my double slit experiment blog, visit:https://theoarmi.blogspot.com/2020/05/double-slit-experiment.html otherwise you wouldn't get the concept behind the experiment]

We can conclude from double slit experiment that electrons show particle nature in the presence of an observer machine and show wave nature in the absence of same; Which indicates electrons somehow know whether they are being observed or not so that they can act accordingly.

That's Scary right! but there's a scientific explanation to the fact that doesn't completely but somehow justify this weird behaviour. Physicists say that there is a fuzzy space between creation and detection where any type of well defined particle doesn't exist at all. Copenhagen interpretation tell us that in this space a particle exist in the form of wave function[it is basically a distribution of all possible properties of a particle], this Probability is wave only which shows wave nature and form interference pattern but when an observer is placed the wave function collapse and the wave converts into particle which shows particle nature and form just two lines on the back wall.

 In double slit experiment we placed an observer machine to detect which electron passes from which of the two slits but we failed in doing so thus Physicists executed Delayed Choice Quantum Eraser Experiment.

Before we go through delayed choice quantum eraser experiment we should first understand wheeler's Delayed Choice Experiment.

In Double Slit Experiment we kept the observer machine before the slits but in wheeler's Delayed Choice Experiment it is kept near the wall[on which patterns appear] and tried to observe the electrons exactly before when they collide so that they can't alter their behaviour accordingly. But the observations were shocking and weird, when electrons were observed they behave as particle and only for two lines ensuring particle nature and when they weren't observed they show wave nature and form interference pattern. Since the observer was observing the electrons just microsecs. before collision; this can be true only if electrons time back in time and decide their behaviour depending upon observance and non-observance. This experiment has again proved that Quantum Physics is weird.

Now, we shall see Delayed Choice Quantum Eraser Experiment:

In this experiment a Non-Linear optical crystal is placed behind the double slit which create entangled pair of electron passing through slit A and slit B moreover one particle of the entangled pair is allowed to move towards the backwall while other one is send towards the detector D3 and D4 in order to predict that electron has passed through which slit(either A or B).

[NOTE: If you don't know about entangled pairs, you should read my blog on Quantum entanglement and EPR Paradox, visit:https://theoarmi.blogspot.com/2020/08/quantum-entanglement-and-epr-paradox.html]

The Entangled Particles are entitled as "twin brothers". whatever happens with one, it also happens with other. If electron's second entangled partner is detected near D4 then electron must have passed through slit B but if second entangled partner is detected near D3 then electron must have passed through slit A. These Detectors are positioned in such a way that the second entangled particle should reach them after the collision of first one on the back wall. Don't be perplexed at all; the big picture is that we can accurately predict electron has passed from which of the slit(either A or B). But in this experiment electrons only show particle nature and form just two lines on the backwall. It seems like second entangled partner of electron which is detected(either by D3 or D4) send information to first one that observer knows the passage of electron and thus ensure particle nature.

Later on some additions were made in the experiment; Half silvered mirrors were placed in the paths of detectors which ensure 50 percent chance of reflection and 50 percent chance of transmission. After that a Quantum Eraser was used which means now electrons can be detected near detectors D1 and D2 too. when electrons were detected near D1 and D2 then there was no possibility to predict the passage of electron(which means we don't know electron has passed from which of the slits ). Now, in this case electrons show wave nature and form interference pattern on the back wall. It seems like second entangled partner of electron which is detected(either  by D1 or  D2) send information to the first one that observer doesn't know the passage of  electron thus ensure wave nature.

This is very weird right! but the weirdest thing is that when second entangled partner send information to the first one, till that time first entangled partner has already collided with the wall. Inspite of  this the alterations in the patterns on the back wall due to observance and non-observance indicates that electrons travel back in time and decide their behaviour accordingly.

Yeah, Quantum Physics is really very weird but nevermind; In future we might get our answers.

TIME CRYSTAL: A NEW 4-D MATTER

 BY: Arjit Mishra

The act of Modification of theories into facts is ,always in continuation and will continue in future. The biggest prophecies of Theoretical Physics like- Einstein's gravitational waves, Higgs Boson, etc. have came into being by experimentation. Recently Scientists have discovered a new and rare state of matter, which was first theorized in 2012 but the theory was unfortunately rejected.

This new state of matter is often called Time Crystal. The interesting fact is that the Atomic state of this state of matter repeats in space-time, which means Time crystals are 4-dimensional objects. Till now we have only examined 3-D matter but in today's Blog I will describe a 4-D Matter.

What are Time Crystals ?

Before I will explain you the concept of Time Crystals, firstly we should know about crystals :

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. simple examples are-Diamond and pieces of ice.

if we observe Atomic structures of simple 3-Dimensional crystals, we can say that they repeat their arrangement to some extent in space but Time doesn't effect it's arrangement. which means if we observe a diamond now and observe it again after few hours their would be no change in it's Atomic arrangement.

Now coming to Time Crystals: In case of Time Crystals atoms not only repeat their arrangement in space but also in Time and because of which their shape changes every time on it's own without any force and they always remain in perpetual motion, They can't attain thermal equilibrium state because they are non-equilibrium metals, very much different from simple theory crystals.

How Time Crystals Work ?

Normal Matter: Suppose we have a simple crystal in which atoms repeats their arrangement over space. If we provide some energy from external source then the energy would flow adjacently in the atoms till all the atoms attain thermal equilibrium which is often called Zero point state, In this state heat is equally divided among all the atoms and thus in most of the cases they don't have enough energy to cause motion because of which they stops.

 for understanding this in a more simpler way let us take an example- when we kick a football, it stays in motion for few seconds and eventually stops but football in state of rest can't come to the state of motion on it's own.

Non-Equilibrium Matter: In case of Time Crystals, Atoms in Quantum Entanglement are arranged in repeated patterns. So as the Energy reaches an Entangled particle it's entangled pair came to know about it instantaneously (independent to the distance between them) and before energy actually reaches to the entangled pair, it starts to react because of which all particles come into the state of motion and this reaction exists perpetually that's why the Time Crystals can't attain the state of Thermal Equilibrium and show movement even in their lowest energy state.

 [If you don't know about Quantum Entanglement visit- Theoarmi ].

Idea behind Time Crystals ?

In 2012 noble prize winner Frank Wilczek thought of a crystal which breaks time translation symmetry. Time Translation symmetry says that "Laws of Physics are applied equally in all the places of UNIVERSE and in all the times which have ever existed." Till many years we have believed that symmetry is always same in Laws of nature but eventually we came to know that Deviation occurs in the symmetry of Laws of Nature. Some object breaks this symmetry by staying in their ground state without breaking the laws of physics. Frank thought that if symmetry breaks in the space then it should also break in Time. He imagined a crystal which could break the symmetry in time that's how Time crystal was Discovered but theory of time crystal was approximately same as the theory perpetual motion machines which can work till eternity without any Energy. According to physics laws these machines can't be invented in reality that's why theory of Time Crystal was also rejected. Later on scientists corrected and modified this theory with help of Quantum Entanglement and Non-Equilibrium metals. With the help of two different experiments scientists have made Time crystals in a Lab.

How can they be useful in future ?

Time crystals could be useful in Quantum Computing, Physicists can use these Time crystals to build stable Quantum system which would work efficiently even on higher temperatures. Discovery of Time crystal is just an initiation, what would happen in the future would be amazing!

SCHRÖDINGER'S CAT EXPLAINED

BY: Arjit Mishra

For understanding this UNIVERSE in a better way we have divided Physics into three parts- Classical Physics, Modern Physics and Quantum Physics.
In Classical Physics this UNIVERSE can be described with simplicity because If we study the past behaviour  of an object then we can easily tell it's future behaviour. Moreover by it's present behaviour we can easily tell what would have happened to it in the past. for example- If we know the speed with which Earth is revolving around the Sun then we can easily tell, In which month Earth was/will be present at which position. In fact we can tell 2 yrs. ago It was present at which position.

But If talk about Quantum Physics, It completely changes our perspective to observe this UNIVERSE. In this we try to understand the behaviour of sub-atomic particles like- electrons, protons, photons,etc. Here we can't Predict the results of experiment before; If we repeatedly conduct the experiment, then too! . We know that Quantum Particles can be present at multiple Locations at a same time and can behave differently at a same time whiz believed to be Impossible in Normal world. we can't even Logically expect ourselves to be present and behave differently at different Locations.
That's why the Laws of Classical Physics are not applicable in Quantum Physics and the world described according to Quantum Physics can't be seen in Reality. Quantum Physics is considered as weird but Scientists believe that actual word can only be studied through Quantum Physics.

Today's Blog is about a Thought Experiment through which a Physicist known as Schrödinger described that, with Reference to bigger objects the Principles of Quantum Physics are weird and Pointless, this Experiment is Popularly known as Schrödinger Cat Experiment.

Many Experiments of Quantum Physics have proved that till when we don't observe the Quantum Particles, They exists in all the possible states of themselves at the same time which is known as Superposition state and as we observe them through any of the suitable instruments, their wave function collapses and a single possible state is selected from the treasure which becomes our Reality.
Our instruments can only see the state which is called "Result". Which means we can't tell the Result of the experiment without actually conducting it because we can get any of the possibilities as Result.
If it is true then it should be applicable on humans, animals, and everything that we can easily observe because they are also made up of Quantum Particles but we know that this is not true and every easily observable things are observed in a single state only! not more than one. for example- A car, either can be in rest or can be in motion at a time not can be in both rest and motion at a same time.

Schrödinger was not able to swallow this theory beyond his throat, which is also known as "The Copenhagen Interpretation". to showed Quantum Theory is Rubbish with Reference to Bigger Objects He take a count on a Thought experiment which is famous in the name of Schrödinger Cat Experiment.

In this experiment He trapped an Alive cat inside a Box, Along with the cat He also put a radioactive substance, a poisonous gas bottle, a hammer and a radioactive sensor in the box.
The radioactive substance was such that it's probability to decay was 50% and a hammer was attached to the radioactive sensor through a string and the poisonous gas bottle was put on the surface of box such that the heavier part of hammer was present just above to.
As the decaying of radioactive substance starts, sensor detect it and after that the hammer fall on the poisonous gas bottle resulting in death of the cat.
Till when the box is closed we don't know what is happening to the cat inside the box, is it Alive or Dead. And as we open the box, then only we can tell that the cat survived or not.
If we imagine cat as a Quantum Particle and apply the superposition principle then we can say that when box was closed and no one was observing the cat, then cat in the box exists in both of it's possible states. yes! there can be only two possible states only, either it is alive or dead which means at the same time the cat was alive and dead inside the box. when we open the box it's wave function collapses and one state is selected from two of it's possibilities and that state becomes our Reality.
That's the reason if we conduct this experiment repeatedly then every time we would get different outcomes or more specifically sometimes cat would be found Dead and sometimes it would be found Alive.

Our common sense says that when box was closed, at that time only either cat survived or lie dead.
If the cat was dead then after opening the box it would be dead only and if it survived it would appear alive to us but it is not possible that at a same time the cat was Alive and Dead both together.
which means it doesn't make any sense that if we observe it or not but Quantum Physics don't work according to our common sense. Infinite experiments proved that Quantum Particles don't rely on our thinking and always show weird behaviour, it behaves to an extent that in normal life we can't even think about it.

Many World theory is a very exciting theory which describe that "Every possibility comes to reality irrespective of the location, time and even Universe". which means that if Schrödinger's cat is found dead in this this Universe then it would have be found alive in another Universe. this theory explain it like this way, when box was closed then cat was in superposition state which means at that time it was dead and alive both together at a same time and when we open the box, A split happens in this Universe and because of that it's two copies are formed and amongst one of these cat would be found Alive and it would be found Dead in another one. If this theory would somehow proved to be true then it's implications would be Wonderful let us understand how:

Whenever Universe has the options then it forms number of copies of itself, where everything takes place that has a chance of happening. which means a world must be existing where Adolf Hitler had won the ww2, A world must be existing where Dinosaurs still exists and A world must be existing where Humans have developed a lot. Whatever Quantum Physics is wonderful and this world too.

QUANTUM ENTANGLEMENT AND EPR PARADOX EXPLAINED

BY: Arjit Mishra

Today our whole Scientific Community agree to the fact that the Quantum World is intensely mysterious and weird because in this stuffs don't work according to our thinking. 

when Quantum Theory was new, It  has bothered number of scientists back then which includes Albert Einstein too.

Actually Albert Einstein was not able to swallow the Theory beyond his throat because predictions of Quantum Theory were literally weird. So to prove this Theory wrong, he though described a Thought Experiment with his two colleagues, which he named EPR Paradox. and this thought Experiment birth an unique phenomenon which is still a topic for research due to its weird behaviour. This phenomenon is called Quantum Entanglement. Einstein and his colleagues just created the base of EPR Paradox to defy the concept of Quantum Theory but happened contrary. Actually when Einstein and his colleagues discussed about EPR Paradox ,then there were no required instruments to go for experimentation that's why it has been treated as a Thought Experiment, because of which any conclusion can't be made. 

But after some years when they have required instruments, they Experimented it and found that Einstein and his colleagues were wrong, not the Quantum Theory because the results of the performed experiment were same as predicted by the Quantum Theory.

As Quantum Theory and it's weird predictions were true, It has completely changed our visionary perspective for the REALITY. Today Scientists agree to the fact leaving no room for debate that

the Real Nature of this UNIVERSE can only be explained by the Quantum Theory.

In 1920s Nature of Reality was the biggest Topic of Debate between Einstein and Neil Bohr.
Einstein believed that our reality is always fixed that's why there is no difference in it's format, if we observe it or not. He said Moon is always present at it's position whether we observe it or not, In fact our whole classical physics is based on this notion and we blindly believe that entities present near us that we are observing are present in same nature and position at the time when we are not observing them.but Quantum Theory doesn't agree to this notion and believe in fuzzy nature of Reality.

Neil Bohr believed that In the Quantum World and in absence of observations and measurements our Reality do not exist, In case of Quantum particles till when we don't observe or measure them we can't tell anything about their characteristics because before observation and measurement they are actually not in a well defined form instead they exist in all the possible states of themselves together which we call Superposition state and till this time physical nature of Reality doesn't make sense at all because till then there is no physical form of these Quantum Particles and the Reality form of this time can only be represented by Wave Function which itself describe the superposition state but as we observe and measure these Quantum Particles their wave function collapses and because of this, A single possible state is chosen from all the possible states it could ever have and in the end this state is obtained; After our observation and measurement we only get a single possible state and because of this we come to a conclusion that this state only is the Reality of that Quantum particle but actually amongst all those possible states any one could be obtained and this means it is not fixed that after observation or measurement which possible state would be obtained. thus in the absence of observation and measurement our Reality doesn't makes sense.

The Copenhagen Interpretation is based on this theory which is believed to be true in the Quantum Mechanics.(I will make a separate Blog on this concept later. )

Anyway, Einstein can't swallow Neil Bohr's theory beyond his throat. He thought everything is Real always and doesn't rely on our observation and measurement.About the Weird predictions of Quantum Theory Einstein said that the Quantum Theory is still incomplete and lacks some Local hidden variable which can be used to predict everything accurately so that we don't need the concepts of superposition state and wave function. Einstein with Boris Podolsky and Nathan Rosen designed the base of EPR paradox to prove Neil Bohr's theory wrong, which itself was the good example of Quantum Entanglement. Actually at that time required equipments were not present which could test Neil Bohr's Theory that's why EPR paradox is considered as a Thought Experiment at that time.
In EPR paradox, paradox word is used because in this experiment the information between the two particles is travelling more than the speed of light which is violating the rule of Einstein which states-"Spread of Any information in this UNIVERSE can achieve maximum to the speed of Light ."

Let us now understand Quantum Entanglement :

To understand Quantum Entanglement we should firstly understand these two concepts:-

1- Superposition State: As I have already described, in absence of observation and measurement Quantum particles do not exist in their single possible state instead they exist in their all the possible states.
 for example-

 There is a intrinsic property of subatomic particles like electrons which we call 'spin'.
 [NOTE- don't confuse spin to be something like electrons are spinning on their axis, no please not I will describe spin in later Blogs]

now the electron has two possibilities in aspect of spin, 'up spin' and 'down spin'. According to superposition principle the electron is not present in one of the single possibilities mentioned above, but occur in both possibilities together, means the existence of 'up spin electron' and 'down spin electron' together.

2- Measurement Rule: It states that till when we don't observe Quantum particle it occurs in superposition state but as we observe or measure the Quantum particle it's wave function collapses and in the end a single possible state is obtained which becomes our Reality.

In Quantum Entanglement Entangled particles are used, let us understand what are Entangled particles and how they are formed:

Imagine we have a energetic Photon, and this energy can be converted to mass using Einstein's mass-energy equivalence. for example we can make other different particles using photon but our UNIVERSE has laws which decides how and what would be the nature of these particles, as photon has no electrical charge that's why the electric charges of produced particles must add up to zero.
which means if a photon produce a electron then it should produce a positron to maintain the electrical neutrality. along with this there is a property which is called as conservation of spin-
photons have no spin but electrons and positrons have their spins, it can be 'up' or 'down' and one of them must have 'up' spin and other one must have 'down' spin because then only they add up to zero spin(which correspond to photon) but we can't specify that which one would have which spin. if we take the perspective of superposition state, till when we don't observe and measure them they occur in 'up state' and 'down state' together. now if we talk about Entangled state, it is the state in which two particles are linked in such a way that they exist only in combined state which means without knowing the states of both the particles we can't define the state of a single particle. if you didn't get it yet understand with an example- we have an electron and a positron, there spins could be 'up' or 'down'. which particle have which spin that we don't know. In superposition state it can be represented as: 

here electron and positron are in 'up-down' and 'up-down' spins together. which means without knowing the state of one we can't tell the state of the other and in conclusion we can say that in Entanglement, particles can only be described through joined states.

According to EPR paradox  or Quantum Entanglement if we have two Entangled particles and if we somehow get the state of one particle then we can surely tell the state of other particle irrespective of  their distance. for example- after measuring if we get the spin of one particle to be 'up' then we can tell that other particle would have it's spin 'down' and vice-versa. Quantum Theory explain it through this way- As we have two Entangled particles, there properties are linked in such a way that both can exist only in combined state. Before measuring both particles are present in superposition state, which means electron and positron have their spins 'up-down','up-down' together. it can be represented as:

but as we measure any one of them, their wave function collapses and amongst their two possible states only one would be selected .

if we get spin of first particle to be 'up' then second one would have 'down' spin.

or if we get spin of first particle to be 'down' then second one would have 'up' spin.

As Entangled particles exist in combined state only, it doesn't makes sense that these two particles are kept at which distance from one-another. the effect is instantaneous and is independent of distance.
which means if we keep one particle in first end of the UNIVERSE and other one in the second end of the UNIVERSE, then also spin state observed in the first particle changes the spin of other particle and would be instantaneous. As the state of Entangled particles depend on the measurement and observance of one of the particle present in Entangled pair, it can be seen that these particles inform their states to each other with speed more than Light. but Einstein's special theory of Relativity states that-"Spread of Any information in this UNIVERSE can achieve maximum to the speed of Light ."
then how it is possible that Entangled particles present in two different ends of this UNIVERSE effect each other instantaneously because if the exchange of information is taking place with the speed of light then also information should take much Time that's why Einstein called it a paradox.
Einstein agree to the fact that if two particles are away from each other and if we know the state of one particle, state of other one could be found but he didn't agreed that information between them can travel with the speed more than the speed of light. He believed if we have local hidden variables and if we somehow able to  know the state of one particle then state of other particle could be obtained at that time only, information doesn't need to travel with the speed more than light.

Quantum Entanglement was firstly experimented by John Steward Bell and this experiment has proved the Quantum Entanglement Theory to be true, and it has been tested many times till now.
But it is still a mystery for us that two Entangled particles create which type of medium between themselves that enable them to share the information with the speed more than Light. 

“Life is a field of cosmic consciousness, expressing itself in million ways in space-time through quantum entanglement.”
