Are Consciousness & Matter the Same Thing? What’s the Difference Between Mind & Physical Reality?

Eastwood interview in 1979.

Eastwood worked for a Yale University professor on a secret invention at a private research and development facility at age 13. "We know quantum physics has disproven the classical physics responsible for world problems. Internal Science and International Philosophy can solve world problems and help people achieve their goals."



Are Consciousness & Matter the Same Thing? What’s the Difference Between Mind & Physical Reality?

  • Are consciousness and matter the same thing?
  • What is the difference between the mind and physical reality?

I will answer these questions now.

Consciousness and matter are the same thing

Consciousness and matter are the same thing, only the intensity is generally less with thoughts. Both thoughts and the physical universe are constructed entirely of electromagnetic fields, as explained below.



ALBERT EINSTEIN SAYS: Nothing is what we were taught & everything is a miracle

  • "The only thing that interferes with my learning is my education.
  • "A new type of thinking is essential if mankind is to survive and move toward higher levels.
  • "There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle.
  • "If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales."

Do scientists say that thoughts create matter?

Many top physicists do know that thoughts create matter and reality

Your thoughts can and do create matter. It is the rest of science, media and the world who do not want to listen to what they are saying.



Max Plank

Max Planck, Nobel Prize Winning father of quantum mechanics says, “I regard matter as a derivative from consciousness.” The Observer, 1931.



“The doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with quantum mechanics and with facts established by experiment.”

— Bernard d’Espagnat, a top theoretical physicist.


If thoughts formed matter, wouldn’t science know?

Mind forms matter presents the facts: Science admits that it doesn't know what anything is.
Since everything is electromagnetic energy and science does not know what electromagnetic energy is, scientists don’t know what anything is.

The scientific establishment does not know what an electromagnetic field is, and since everything is an electromagnetic field, External Science does not know what ANYTHING is.

If you ask a scientist what an electromagnetic field is, 99% will say “it is a fundamental entity, it’s not made of anything else, it just is what it is.” They leave that question to philosophers because they cannot answer it.

Quantum physicists, however, sometimes go beyond conventional ideas because of the nature of their work.

Why people see what they want to see, and create negative experiences

“Each person reads and experiences reality according to what they believe exists. If they hold a view of reality within themselves that is inherently limiting and/or negative, then this inner subjective reality and nothing else is projected outward into events and experiences so that everything conforms with their beliefs. They then cannot see anything outside of their own worldview. In effect, they become blind to any information that would free them from their inner and outer restricted reality.

“The negative focus on perceived enemies or opposition combined with the overlooked and unchecked power of consciousness and focus has been causing the world severe problems for a very long time only because we do not see the obvious.

“The solution is to understand that consciousness is altruistic.

“The people that seem evil don’t believe that the human spirit is basically good, and that’s the problem.

“My work is to explain that this is a scientifically validated fact in order to bring an end to global conflict and assist humanity in advancing into a new stage of incredible fulfillment, both private and public. That work begins with you.

“You can become a good or bad person in this life of yours — it is your choice.

“Yet, regardless of what you make of yourself in this life, your innermost soul is good. What you are at the deepest level IS good.”

— William Eastwood


You can get lost trying to understand consciousness by reading scientific articles. I offer links to some excellent scientific studies as a courtesy to you only. I know in simple terms that the physical world is a projection we each create with our own consciousness. If four people enter a room, there are four rooms. I figured that out over four decades ago.

Consciousness is irreducible and is both individualized and part of an unbroken field. Quantum mechanics is the study of that field of energy. Your consciousness has very deep, eternal meaning that cannot be measured with a ruler, and so all scientific studies will miss that part of the picture.

All consciousness is of an equal, amazingly high grade; and just so you know, your personality and individuality will never be lost. Who you are will survive death. I am not a religious person, because I will add that you are also good, and most religions will say you are evil.

Ignorance is separation from truth, and it is the closest thing there is to evil. Our civilization has been based on separation from truth for centuries and we therefore do not even know where we come from! That shows just how ignorant we are.

Our civilization has been reading reality backwards for thousands of years. You cannot understand reality by looking at the physical world because that world is a consciousness hologram that you are creating. If you follow most scientists, they will just get you more confused.

I provide hundreds of articles and over a dozen books in plain English, and you do not need to be a scientist to understand any of it. Use your heart and intuition. All knowledge is within you, and you are a portion of the Divine consciousness that forms everything. You are forever safe and loved, and this will never change, not for a billion years.

For those who are interested I often begin my articles with some science because it is important to use your intellect. For something to be true it must make sense to you both intellectually and intuitively.

We are not the only ones saying there is a new paradigm in science that is being ignored, (click below for an example).




Objective science hasn’t answered important questions

What is an electromagnetic field?

The scientific establishment does not know what an electromagnetic field is.

If you ask a scientist what an electromagnetic field is, 99% will say “it is a fundamental entity, it’s not made of anything else, it just is what it is.” They leave that question to philosophers because they cannot answer it.

Further into this article I explain why traditional science cannot go deeper than electromagnetic energy. Science as it is traditionally practiced can probe down to the Zero Point Field, but no further. New science — Internal Science — however, can probe deeper. Using the methods of Internal Science, the concept of a CEU arises to explain what electromagnetic energy is composed of.


Science Does Not Know What Fields Are


A wave, electron (matter) and a photon are an excitation of an electromagnetic field; thus, a wave, electron (matter) and photon are in essence an electromagnetic field. All three are different states of the same thing—the fundamental electromagnetic field — so, what is an electromagnetic field?

The scientific establishment cannot tell you what electromagnetic fields are. A few will tell you, however, that consciousness is an electromagnetic field. I agree that consciousness is an electromagnetic field. It is also more. Consciousness contains properties of sound and light woven into its substance.


Consciousness Is an Electromagnetic Field


Those who believe in materialism / physicalism make a division between mind and matter. Doing so is an error. Everything is a state of consciousness. Even objects and events are a form of consciousness projected by and registered by our senses as a solid. It is our senses that create the impression that we call solid matter.

Everything is an electromagnetic field. Nothing else exists. All scientists will agree.

Since science as a whole does not know what an electromagnetic field is, orthodox science does not know what anything is. Yet science claims to know that thoughts do not create matter!

We can thus safely say that the formula below could be correct — it is not disproven.




Consciousness = Electromagnetic field = Matter



Albert Einstein on intuition and new (Internal) science

Albert Einstein thoughts create matter physical illusion
Albert Einstein transcended the scientific intellect to acquire E=MC² and to become the definition of genius in the eyes of the world. The knowledge he tapped is in you. This is International Philosophy and Internal Science.

“The only thing that interferes with my learning is my education.

“I didn’t arrive at my understanding of the fundamental laws of the universe through my rational mind.

“The man of science is a poor philosopher.

“I never made one of my discoveries through the process of rational thinking

“I believe in intuitions and inspirations…I sometimes FEEL that I am right. I do not KNOW that I am.

“The only real valuable thing is intuition.”

― Albert Einstein.

What is Internal Science and how can it help me?

Internal Science by  William Eastwood, is a more accurate and complete paradigm of reality. Working for a Yale University professor at age 13 and studying holographic reality to help people achieve their goals and solve world problems for over 45 years, Eastwood is now the author of over 20 books and 100's of free articles based on Internal Science.

Albert Einstein's friend and colleague, physicist David Bohm, introduced the science and Eastwood translates it into simple terms to show us how we can create whatever we want in life.


Reality is a projection—Internal Science—the right science

David Bohm, Einstein's friend and one of the most important 20th century physicists that said there is not sharp distinction between thoughts and matter
Einstein's friend, David Bohm.

Physicist David Bohm, — who Albert Einstein called “a kindred spirit,” and whose Ph.D. thesis — being top secret and classified — was awarded at the University of California at Berkeley by none other than Robert Oppenheimer — tells us that our physical reality is a holographic projection of the brain and five senses.



How you are creating a three-dimensional movie—your life

Thoughts create matter: A virtual reality headset
Virtual reality headset.

Imagine that in your living room you put on a holographic headset. At the click of a switch, you seem to no longer be in your living room.

Your senses are now telling you that you are actually on a tropical beach. As you reach down to touch the imaginary sand, sensor pads in gloves you are wearing give the sensation of pressure on your fingers.

This is an analogy to explain the purpose of your body and brain. Your body and brain are like a holographic headset that allows you to perceive a 3D movie you call your life.


Events are a projection of your mind and five senses

The Holographic Universe Journey Out of the Illusion by William Eastwood book thoughts create matter reality
William Eastwood.

Eastwood brings you the greatest news story ever! Revolutionary discoveries by Einstein and other great physicists that were blocked by the elite are revealed.

Eastwood takes power away from those who hold it over others and invests the common man with power and control over his destiny. Get it now and your life will change forever!



"Your environment is a projection of the mind that you control. You can create anything you want in life."

— William Eastwood.

Why is Eastwood someone we should listen to?

"I knew that the Universe was a projection of the mind at age 12 and that External Science was misleading us all. I was upset by the flawed nature and negativity of external science, and so I created Internal Science, a more accurate paradigm of reality.


"Infinite wisdom is within your own consciousness and is trying to get your attention. Don't let your education interfere with your learning."

— William Eastwood.


"Science belongs to everyone, and so rather than use the complex terminology of the scientific elite, I aligned with every man, woman and child to make the truth accessible and helpful to everyone. The world is in a dangerous trance, and "The Holographic Universe — Journey Out of the Illusion," breaks that trance and reveals the greatest news story ever, that should have happened but didn't.

"At 12, I left the academic community in order to be intelligent. I left the allure of acclaim to be my authentic self — a humanitarian assisting everyone everywhere with World Help."


The news of the century and your way out of the illusion

Holographic Universe Journey Out of the Illusion book ebook by William Eastwood






Why was "De revolutionibus orbium coelestium," so important in world history?

"De revolutionibus orbium coelestium," was important because from it we learned that the earth was not the center of the universe. The same thing is happening again. We are learning that the universe is not what we thought it was, and "The Solution..." has experienced the same level of VIOLENT resistance as Copernicus's book.


The intrigue, the confiscations... what is so important about this book?

Thoughts create matter presents: The Solution by William Eastwood.
Eastwood's 450 page debut.

"The Solution..." has the intrigue of Nicolaus Copernicus's "De revolutionibus orbium coelestium," a book that changed the universe. The second editor, with two doctorates in theology, endorses the twice confiscated manuscript "We can literally change the course of civilization by lifting the race to a higher path through implementing the solution." — Mario Fusco, TH.D., RS.D, B.S.C.

The Rosenthal effect explains why scientists can prove their theories even if they are incorrect! This is the smoking gun everyone is looking for that shows that beliefs create reality and is the reason why modern science has created a dangerous false science.

Eastwood does not use scientific terminology that is difficult to understand. Every book he writes tells you how to create what you want in life in a plain and simple language that anyone in any country can understand. 


“Consciousness is altruistic, and that means that you are an amazing, powerful and beautiful person."

— William Eastwood.

Why is Eastwood someone we should listen to?

Is it because he worked for a Yale professor in a research and development facility on a mysterious invention at age 13 — a modern version of an astrolabe accurate enough to be used by surveyors?

Not necessarily. But it does make you wonder what this kind of person wants to tell you after 45 years of research into the holographic nature of the universe — a study some people do not want you to read.

There is something in this book that undermines the official picture of science for the past three centuries. But that's not what bothered certain government agents. There is only one parallel in history.

"People who go around learning on their own often turn out to be pretty interesting themselves." — Carolyn Battista, 1979 interview of Eastwood at age 16.


A book that is the solution to all your problems


The problem with scientific physicalism

The inability of a person to accept something that is opposed to their worldview is called cognitive dissonance, and this is the reason for the division and problems we are facing in the world today.


The fact that people project their beliefs fools them into thinking that their beliefs are reality.
A website article.


Even most scientists are unable to conceptualize a worldview beyond their own. The problem rests as much with the educated as with the ordinary man, woman and child. The scientific elite bear most of the responsibility for world problems today since most people look to them for answers. We expect scientists to know something about reality and to tell us the truth, but that is not what is happening.

I am not talking about climate change, which is a reality. I am alluding to something far deeper that requires considerable objectivity to even consider. Our reality is not what we (most of us) think it is.

The majority are more interested in defending their dogmas than seeking the truth, and the truth is C=Ef=M. Even worse, the situation is similar to what happened in ancient Greece when Socrates was made to drink Hemlock. His death sentence was termed, “corrupting the morals of the city youth,” which was legal jargon for educating outside of officialdom.

I know first hand that the same charge has been used in the 21st century for the same reasons.

The exceptions are a handful of world-renowned physicists who are trying to get our attention, but people are not listening to what they have to say.


The world is in a dangerous trance, under an unnecessary damaging collective hypnosis.

The world is not dealing with facts of existence, but is believing whatever they want to believe, and this is a dangerous situation. The true nature of reality is actually much more positive than most people want to believe.

“The Holographic Universe — Journey Out of the Illusion,” “The Altruism Code — Your Protection,” and “The Power of Positive Thinking — How to Think Your Way to Success,” are ways out of the damaging and dangerous trance the world is in.

Your way out with my books.




How different paradigms required different methods of establishing facts

The premise of new science which I like to call Internal Science, is that consciousness creates everything in all dimensions of existence. Because consciousness is a subjective phenomena, this poses special problems for scientists who insist on objectivity.

Physical scientific instruments are designed to probe physical aspects of the universe. They cannot register or probe into the nonphysical subjective substance of the universe any more than a microscope can allow you to look at love or compassion. Consciousness always escapes the scrutiny of the physical instruments that traditionally science has used to study the universe.

In fact, the reason why the physicalism paradigm exists at all is because of this fact. The scientific instruments used in the scientific method of gathering information don’t see the vast inner reality of existence any more than our eyes see the air around us. As a result, inner reality is absent from the paradigm of reality that mainstream science settled on in the last two centuries.


To those who insist on the old belief systems and feel threatened by the new science I say, “I didn’t create the problems in the world today.”

I am offering the world something that actually works

William Eastwood on world problems and climate change
Eastwood today.

When it comes to solving world problems, the more conventional approaches don’t work — they are what got us into trouble in the first place. I am offering something different that will stop violence, division, unhappiness, illness, and will create peace and prosperity.



“The doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with quantum mechanics and with facts established by experiment.”

Bernard d’Espagnat, a top theoretical physicist.



What does that statement mean?

It means that your consciousness is connected to physical objects. You can attract wealth, money, love, health or anything you want with the simple principles given in these books. I created these books to provide simple and easy to understand principles anyone and everyone can use to improve their life. These books all make your goals easy to achieve.


Thoughts create matter presents: The compounded placebo effect.
A website article.


Consciousness is a first substance, and out of it can only come more consciousness. Particles are just that — a mirage of our senses built up out of consciousness particles I call Consciousness Energy Units (CEU’s).

CEU’s follow the strange laws of quantum mechanics. They violate the laws of classical physics by moving through matter, being in two places at once and travelling faster than light.


CEU’s cannot be observed by scientific instruments because they are far too small. Many millions of them can fit in a virtual particle.


Objectivity cannot discern what exists in a subjective world. But consciousness itself can. Only consciousness can probe into the inner reality that forms the physical universe. Thus, consciousness must be used by science to go beyond current limits.

I want to emphasize that what I understand about CEU’s does not come from any traditional method of establishing facts, which would be impossible because of the extremely small size of CEU’s.

As a new scientist, I have gone beyond the limits of conventional science.

If a scientist trained in the old methods tried to do the same, he would get to the Zero Point Field and no further. Drawing diagrams of the particles there is futile because diagrams cannot convey the reality of what is actually in existence at that level any more than a stick figure could convey the reality of a human being,


A website article.


There is a really big difference between how new scientists gain understanding and traditional methods of ascertaining facts. The scientific method relies on physical instruments whereas Internal Science relies heavily on consciousness itself.

With physical instruments, science cannot probe beyond the smallest known particles. This limitation does not apply to new science however. One has to concede, therefore, that the methods used by new science are superior.

Consciousness can probe deeper into the physical universe than any physical scientific instrument can. However, consciousness can distort reality or we wouldn’t have a problem with conspiracy theories.

We thus are forced to gauge the accuracy of what is discovered using our understanding of reality. Intuitive knowledge must agree with intellectual assessment. This is only possible if we understand the basics about reality. Distortion is a product of false beliefs. If we think reality is purely physical like a rock is, then we have false beliefs that will distort our understanding. To compile facts about reality that are accurate we must understand that physical reality is a projection of consciousness.

I have lived within this paradigm my entire lifetime and what I have gained in this way is that CEU’s create reality. Electromagnetic energy is an expression of smaller CEU’s.


As previously written on the subject:

Because of their extremely small size, these units cannot be studied by physical instruments. Being composed of such units, however, implies that we are in possession of all information pertaining to the functioning of consciousness. Being composed of CEU’s, we possess the knowledge of CEU’s.

New science is geared toward methods of acquiring this information by probing inner reality via the vehicle of consciousness itself.  Those who are well trained can retrieve information in this way. The lesser the skill, the greater the distortion. However, there is a general consensus among those who are able to do this with a minimum of distortion.

I am a new scientist engaged in these activities. I use my own judgement and combine what I find out with the findings of others, and in this way I can provide you with relatively undistorted information.

Multidimensional travel through time and space.
A website article.


Einstein’s colleague, David Bohm explains that everything in existence is one unbroken field of energy which he calls the holomovement. He divides the universe into two states, 1) manifest and 2) unmanifest.

Bohm calls the unmanifest “information” or the implicate order, and the manifest he calls the explicate order.

The entire universe exists first as an inner energy of unlimited potentials. From an inner world of pure information and probable events, David Bohm says, that physical, observable phenomena unfold according to instructions given from within information in the wave. That process of manifestation has been called the collapse of the wave function by many scientists.




Science has also established that their are no physical particles, only fields of energy.


A website article.


If all of reality is one substance (as Bohm says it is), then that means that the un-manifest and manifest states are the same thing. This implies that your thoughts and matter are the same thing. Combine that conclusion with Bohm’s science that says information determines what manifests and it implies that everything is consciousness and consciousness forms matter.

Bohm’s holographic reality theory states that the mind, brain and five senses project reality. This is what Eastwood discovered in the 1970’s, years before Bohm published Wholeness and the Implicate Order” in the 1980s.

Take all these facts together and there is only one possible explanation.

It is this:


EASTWOOD: I published and copyrighted “C = Ef = M, but I did not arrive at that conclusion through complicated mathematical formulas. By virtue of the fact that all information is holographically enfolded in each “portion” of the universe, I can access that knowledge through my own consciousness, which is how I know that C = Ef = M is fundamentally correct. C = Ef = M is how the universe operates.

I do not necessarily agree with all that Bohm or any single scientists claims. But I know that taken together, all these scientific theories and facts point to C = Ef = M. That is confirmed.

Are Consciousness and Matter the Same Thing? What’s the Difference Between Mind & Physical Reality?

Scientists do not usually wonder if there is a nonphysical source for physical reality because the question would make no sense in light of widely accepted materialism. The scientific establishment and the entire civilization that gets its worldview from traditional science has long ago accepted the view that the world operates like a big physical machine.

Scientist do not know what electromagnetic fields are. They leave that question to philosophers (perhaps because they cannot answer it).

There is no real difference between consciousness and matter. This is not a theory this is just a fact. Consciousness and physical matter are both electromagnetic fields.
