"Any intelligent fool can make things bigger and more complex...It takes a touch of genius — and a lot of courage — to move in the opposite direction."

—Albert Einstein

### The unified field as Einstein understood it

The oscillating electromagnetic field, electromagnetic radiation, or light in its most general sense, is the ubiquitous energy of the universe. More importantly, it is the unified field that Albert Einstein was pursuing in his Unified Field Theory.

However, there is a view from Einstein's scientific contemporaries that his work was a failure and there is nothing we can learn from his final scientific legacy. Either that, or he did not complete his work.

### Did Einstein complete his work?

After 1917, Einstein wanted to tackle head on the mystery of the gravitational field once again. Previously he acknowledged a link between the acceleration of uncharged matter and the gravitational field, which is now encapsulated in Einstein's General Theory of Relativity, published in 1916. However, there is something rather peculiar about light that made Einstein pursue the problem of the gravitational field once again.

At first, Einstein discovered a strange ability for light to move uncharged matter. If you need evidence of this claim, you only have to observe a typical Crookes' radiometer to notice how the sunlight moves supposedly uncharged metal plates. Not only that, but it also includes the ability of light to bend in a gravitational field, much like the way a tennis ball thrown throw the air can bend in the same field.

After realising light can bend in a gravitational field following the results of the experiment by Professor Arthur Eddington (1882 - 1944) to check the validity and magnitude of the light bending effect during a solar eclipse in 1919 as predicted by Einstein's work, he noticed an unmistakable connection between the electromagnetic field and the gravitational field.

After much careful thinking, Einstein eventually made the decision to see light as ordinary matter. It doesn't matter if you replace light with any other form of ordinary matter, it would make no difference. The same gravitational and ordinary matter effect would exist (i.e., both light bending and moving uncharged matter), and there is no way to discern a difference in this "gravitational" effect. Therefore, we have to see light as like ordinary matter. But what does ordinary matter have as well? As all physicists agree, ordinary matter is known to generate a gravitational field of its own. So naturally Einstein thought, why leave out the gravitational field from the picture of light? Surely, it must make sense to include the gravitational field with the electromagnetic field through radiation.

From this humble beginnings, he formulated the most ambitious mathematical theory ever devised in science: The Unified Field Theory.

In 1924, Albert Einstein *completed* the essential aspects of his unification work. After further refinements, the fully completed version was published in 1929 (you can download the paper from the link below, together with a simplified presentation of the theory by Professor Tullio Levi-Civita). Since then, Einstein remained confident throughout his life that what he achieved was indeed correct and that all he needed was a mathematical solution derived from the unified field equations for a new special case that can be applied to reality and reveal through experimental testing to be true and so prove the validity of his idea behind his final scientific masterpiece.

The only problem with the Unified Field Theory is the complexity in solving field equations in the non-static cases, of which radiation is an example.

But rest assured, there is a way to test the theory. In fact, there are at least two simple approaches one can take to validate the theory, and it merely involves amplifying or reducing the electromagnetic field strength sufficiently to reveal this gravitational field effect from it.

Yet more amazingly, it is not absolutely critical that you need to solve the field equations. Why should you? Simple application of the unified field concept to some of the biggest mysteries of science can actually provide a unique insight and potentially reveal new solutions without requiring one to write a mathematical symbol on paper. Just plain and simple physics applied in a logical way. And before you know it, the impact of radiation in so many areas of science start to reveal themselves.

The idea is not complex or difficult to understand. But its application is even more startling simpler. And with it, new solutions emerge for science.

But, of course, the real question remains: What is the gravitational field?

Or perhaps the real question we need to ask is, do we need the gravitational field to explain the gravitational effects seen in light and other ordinary matter?

This book explains from a purely electromagnetic perspective how we can explain the gravitational field and how matter clumps together in a process that was originally called the "gravitational" effect.

More interestingly, physicists may be in reach in unifying all the forces of nature under the umbrella of electromagnetism, with radiation being the prime mover for all things.

### Why haven't scientists solved the Unified Field Theory problem?

There is a serious misconception among Einstein's contemporaries that his approach to a Unified Field Theory got him nowhere and that his mathematical linking of the electromagnetic and gravitational fields in his unified field equations would not explain the weak and strong nuclear forces and anything else about the quantum world. Part of the problem with this is because scientists believe the mathematics behind the unified field equations is too complex (1). Understandable when one inspects the equations. Add to this the difficulty in relating the mathematics of the unified field equations with the real world and seeing a common and natural phenomenon that can be used to help identify practical experiments to support the theory, and most scientists are of the view that Einstein had been unsuccessful in his attempt.

Dr Cornelius Lanczos of the School of Theoretical Physics at the Dublin Institute for Advanced Studies confirms this current scientific belief about Einstein's final work when he said:

"In the meantime,

modern physicscontinues to grow and advance without taking account of Einstein's unifying attempts and, in fact, denying even the possibility of such an attempt being successful." (2)

As a result of this decision not to pursue Einstein's final great theory and understand what he had achieved, a problem has emerged in the world of physics. It is best seen in the quantum world where bizarre solutions appear that seem to defy the normal laws of Newtonian physics. And there is this belief that quantum particles do not have a "cause and effect" solution. It is the result of over simplification of equations used in quantum theory and the decision by physicists not to include electromagnetic radiation (and its gravitational field) into the equations as needed to tame the solutions and show what is actually happening to the quantum particles. But there is also another reason: it is because there is not much imagination applied by physicists to see what is really going on.

As an example, we know the gravitational field equations of the General Theory of Relativity acknowledges the existence of a mysterious and ubiquitous energy permeating through space. Yet it is remarkable that even to this day, physicists have never been able to properly elucidate to the public exactly what this energy is. Instead, they are happy to call this thing *spacetime* or *mass-energy* and leave it as that.

Not any more. There is a way to understand what this energy is in the real world and how it relates to all of physics, including quantum theory. The key lies in Einstein's Unified Field Theory and the behaviour of light.

The new book from SUNRISE will explain everything you need to know about Einstein's final scientific legacy to the world.
