Essay on Life & Ideas of David Bohm

(1917 - 1992)

In autumn of 1992, one of the world's greatest contemporary physicists passed away.
David Bohm, whose work inspired many people all over the world, died in London.
David Bohm's contributions to science and philosophy are profound, and they have yet to be fully recognized and integrated on the grand scale.
David Bohm was born on December 20, 1917, in Wilkes-Barre, Pennsylvania.
Bohm was fascinated by the dazzling concepts of cosmic forces and vast expanses of space that lie beyond our understanding.
Bohm began his theory with the troubling concern that the two pillars of modern physics, quantum mechanics and relativity theory, actually contradict each other.
This contradiction is not just in minor details but is very fundamental, because quantum mechanics requires reality to be discontinuous, non-causal, and non-local, whereas relativity theory requires reality to be continuous, causal, and local.
This discrepancy can be patched up in a few cases using mathematical re-normalization techniques, but this approach introduces an infinite number of arbitrary features into the theory that, Bohm points out, are reminiscent of the epicycles used to patch up the crumbling theory of Ptolmaic astronomy.
Hence, contrary to widespread understanding even among scientists, the new physics is self-contradictory at its foundation and is far from being a finished new model of reality.
Bohm was further troubled by the fact that many leading physicists did not pay sufficient attention to this discrepancy.
Seeking a resolution of this dilemma, Bohm inquired into what the two contradictory theories of modern physics have in common.
What he found was undivided wholeness.
Bohm was therefore led to take wholeness very seriously, and, indeed, wholeness became the foundation of his major contributions to physics.
According to quantum physics no matter how far apart two quanta's of light (photons) travel, when they are measured they will always be found to have identical angles of polarization. This suggests that somehow the two photons must be instantaneously communicating with each other so they know which angle of polarization to agree upon.
Eventually, technology became available to actually perform the two particle experiment, but no one was able to produce conclusive results.
Then in 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century.
There are some who believe his discovery may change the face of science.
Aspect and his team discovered that under certain circumstances subatomic particles are able to instantaneously communicate with each other regardless of the distance separating them. It doesn't matter whether they are 10 feet or 10 billion miles apart.
Somehow each particle always seems to know what the other is doing.
GH - This is correct because matter is actually large, as a Spherical Standing Wave in Space (rather than a 'particle') thus is always continuously connected to all other matter in the Universe by its In and Out Waves.
This meant that either Einstein's long-held theory that no communication can travel faster than the speed of light or the two particles are non-locally connected.
Because most physicists are opposed to admitting faster-than-light processes into physics, this daunting prospect has caused some physicists to try to come up with elaborate ways to explain away Aspect's findings.
But it has inspired others to offer even more radical explanations.
David Bohm believes the reason subatomic particles are able to remain in contact with one another regardless of the distance separating them is not because they are sending some sort of mysterious signal back and forth, but because their separateness is an illusion.
Bohm postulates that the ultimate nature of physical reality is not a collection of separate objects (as it appears to us), but rather it is an undivided whole that is in perpetual dynamic flux. For Bohm, the insights of quantum mechanics and relativity theory point to a universe that is undivided and in which all parts merge and unite in one totality.
This undivided whole is not static but rather in a constant state of flow and change, a kind of invisible ether from which all things arise and into which all things eventually dissolve. Indeed, even mind and matter are united.
Bohm refers to his theory as the holomovement. The terms holo and movement refer to two fundamental features of reality.
The movement portion refers to the fact that reality is in a constant state of change and flux as mentioned above.
The holo portion signifies that reality is structured in a manner that is very similar to holography. Bohm says that the universe is like a hologram.
GH - This is correct, this dynamic flux is caused by the Wave Structure of Matter in Space (One Continuously Connected Wave Medium).
So, in order to understand what that means, we need to have some idea of the components and structure of a hologram.
There are several explanations, but here is something of the idea.
To construct a hologram you need two beams of light (lasers). One beam will bounce off the object that you want as a hologram, and the other beam will shine directly onto the special photographic plate or film.
The interference patterns of those two light sources will interact on the plate. They swirl around and do not look like anything in particular if you are looking at the plate. If, however, you shine a laser beam through the plate of film, the object will be reproduced in the 3-dimensional form of a hologram. And further more, if you tear the plate apart and shine the beam of light through any of the pieces, the whole object can be reproduced.
So, in essence, each part contains the patterns for the whole picture.

One of Bohm's most startling assertions is that the tangible reality of our everyday lives is really a kind of illusion, like a holographic image. Underlying it is a deeper order of existence, a vast and more primary level of reality that gives birth to all the objects and appearances of our physical world in much the same way that a piece of holographic film gives birth to a hologram.
Bohm calls this deeper level of reality the implicate (which means enfolded or hidden) order, and he refers to our own level or existence as the explicate, or unfolded order.
Put another way, electrons and all other particles are no more substantive or permanent then the form a geyser of water takes as it gushes out of a fountain. They are sustained by a constant influx from the implicate order, and when a particle appears to be destroyed, it is not lost. It has merely enfolded back into the deeper order from which it sprang.
GH - The central point here is that our mind represents our senses (due to our evolution based on survival) rather than providing a true picture of reality.

However, reason tells us that matter is clearly interconnected (e.g. the earth orbits the sun) and that there must be knowledge flowing into matter to explain how we can see things around us. This is correct, and explained by the Spherical In-Waves which form the 'particle' effect of matter at their Wave-Center.

A piece of holographic film and the image it generates are also an example of an implicate and explicate order. The film is an implicate order because the image encoded it its interference patterns is a hidden totality enfolded throughout the whole. The hologram projected from the film is an explicate order because it represents the unfolded and perceptible version of the image.
Bohm is not the only researcher who has found evidence that the universe is a hologram. Working independently in the field of brain research, Stanford neurophysiologist Karl Pribram has also become persuaded by the holographic nature of reality. He says that the human brain can be modeled as a hologram.
Pribram was drawn to the holographic model by the puzzle of how and where memories are stored in the brain.
For decades numerous studies have shown that rather than being confined to a specific location, memories are dispersed throughout the brain.
In a series of landmark experiments in the 1920's, brain scientist Karl Lashley found that no matter what portion of a rat's brain he removed he was unable to eradicate its memory of how to perform complex tasks it had learned prior to surgery.
The only problem was that no one was able to come up with a mechanism that might explain this curious whole in every part nature of memory storage.
Then in the 1960's Pribram encountered the concept of holography and realized he had found the explanation brain scientists had been looking for.
Pribram believes memories are encoded not in neurons, or small groupings of neurons, but in patterns of nerve impulses that crisscross the entire brain in the same way that patterns of laser light interference crisscross the entire area of a piece of film containing a holographic image.
GH - This is important, as again it is founded on the principle that matter is large and subtly interconnected to other matter in the space around us, as the Wave Structure of Matter explains / confirms.
Capitalizing on Pribram's findings, Bohm states that our brains are smaller pieces of the larger hologram. That our brains contain the whole knowledge of the universe.
So, you can see how each mind has a limited perspective of the universal hologram.
Our brains are our windows of perception.
Each mind always contains the whole picture, but with a limited and unclear perspective.
We each have different experience in our lives, but each perspective is valid.
Our brains mathematically construct objective reality by interpreting frequencies that are ultimately projections form another dimension, a deeper order of existence that is beyond both space and time.
GH - Time, along with particles, is a human representation, both being caused by the wave Motion of Space (thus the name of this website SpaceandMotion).
So the Wave Structure of Matter is founded on the Metaphysics of Space and (wave) Motion rather than Space and Time. But Space itself does physically exist (as a Wave-Medium).
The brain is a hologram enfolded in a holographic universe.
We can view ourselves as physical bodies moving through space. Or we can view ourselves as a blur of interference patterns enfolded throughout the cosmic hologram. This could be also expressed with the analogy that the brain is like the laser beam that shines through the holographic film to interpret the patterns. As it turns out, you can preserve the interference patterns of more than one hologram on the same film by using various different angles of projection of the laser beams.
Therefore, depending on the direction and frequency of the beam that you send through the film, a different hologram will appear.
So, if applied to the brain, consciousness literally becomes the co-creator of the reality portrayed depending upon its angle of perception. This does not mean that if I am looking at a tree, it is not really there. The tree is there on multidimensional levels, which means that I am seeing a cross-section of the tree depending on the level of consciousness that I am tuned into. If the brain is a decoder of sorts, then it can be tuned to different states or frequencies of consciousness, and I will see different levels of tree reality depending upon which one I'm on.Therefore, mind contributes to the phenomenon of reality itself, not just to the knowledge of it. In a brain that operates holographically, the remembered image of a thing can have as much impact on the senses as the thing itself.
Bohm uses his idea of the implicate order, the deeper and non-local level of existence from which our entire universe springs, to echo this sentiment:
Every action starts from an intention in the implicate order. The imagination is already the creation of the form; it already has the intention and the germs of all the movements needed to carry it out.
And it affects the body and so on, so that as creation takes place in that way, from the subtler levels of the implicate order, it goes through them until it manifests in the explicate.
In other words, in the implicate order, as in the brain itself, imagination and reality are ultimately indistinguishable, and it should therefore come as no surprise to us that images in the mind can ultimately manifest as realities in the physical body.
So it appears that through the use of images, the brain can tell the body what to do, including telling to make more images. Such is the nature of the mind/body relationship in a holographic universe.
According to the holographic model, the mind/body ultimately cannot distinguish the difference between the neural holograms the brain uses to experience reality and the ones it conjures up while imagining reality.
This effect is so powerful that each of us possesses the ability, at least at some level, to influence our health and control our physical form.
Contemporary scientists may ignore Bohm's work (as many have done), but they cannot escape its implications.
His hypothesis is rigorously grounded in the experimental evidence of physics, and such it is not just a new way of thinking about physics, it is a new physics, that is, it is a entirely new way of understanding the fundamental nature of the physical universe, as glimpsed through the data and laws of physics.
It isn't that the world of appearances is wrong; it isn't there aren't objects out there, at one level of reality. It's that if you penetrate through and look at the universe with a holographic system, you arrive at a different reality.
And that other reality can explain things that have hitherto remained inexplicable scientifically: paranormal phenomena, and synchronicities, the apparently meaningful coincidence of events. (Karl Pribram)
Bohm's holographic theory has found fruitful application in brain physiology and human consciousness. This theory opens new lines of research, it predicts hitherto unknown phenomena, and makes some novel predictions.
Bohm points out that there is no scientific evidence that argues for the dominant fragmented scientific world view over Bohm's hypothesis of undivided wholeness. However, while scientific evidence offers no help in this regard, other forms of evidence may, indeed, shed some light on the matter.
For example, mystical and spiritual teachings down through the ages have also spoken about the fundamental interconnectedness of all things.
If Bohm's physics, or one similar to it, Gary Zukav writes in his popular New Age book The Dancing Wu Li Masters (1979), should become the main thrust of physics in the future, the dances of East and West could blend in exquisite harmony.
Do not be surprised if physics curricula of the twenty-first century include classes in meditation.
With the model of the holographic brain, the holographic universe, and Quantum Physics, we could speculate that all that we hold as real is nothing more than the playful dance of light, light that has no dimension and limitless dimension.
The radical implications of Bohm's implicate order take some time to fully grasp, especially for Western minds, but whether Bohm's holographic paradigm becomes accepted in science or not remains to be seen.
