### What is the unified field?

Whether we call rhe ubiquitous energy of the universe as radiation, or light in its most general sense, any time-varying electromagnetic field (where the energy density swings from positive to negative and back again around a mean or central position known as true zero energy, similar to the plucked string of a guitar vibrating from a central position) is the unified field. If you do not have oscillation in the energy, there is no unified field, and that means there can be no gravitational field.

The electromagnetic field must be oscillating to be described mathematically, according to Einstein's work, as a unified field and generating a gravitational field of its own.

### What does Einstein mean by unified?

From Einstein's perspective, it is the linking of the electromagnetic field with the gravitational field. From our research and understanding the problem Einstein was solving after 1917, the electromagnetic field must be oscillating. That was the missing piece in the puzzle for physicists who were trying to understand Einstein's Unified Field Theory. Or as Graham Keith Russell stated in his 1972 thesis titled *The Interpretation of Einsteinâ€™s Unified Field Equations*:

"How do the field equations describe the geometry of space-time, and how do they describe the electromagnetic and gravitational fields in that space-time?"

### What is the Unified Field Theory?

This is a mathematical unification of radiation (i.e., the electromagnetic field) and the gravitational field, which is described by the *unified field equations*. Einstein came to this conclusion after conducting much thought experiments about the nature of light. In particular, why does light bend in a gravitational field? And why does light move uncharged matter?

However, things gets more interesting in our research when we pursue this unified picture to its logical conclusion. In particular, how is the electromagnetic field, when oscillating, any different from an ordinary gravitational field? Indeed, are there any other ways to generate a gravitational field that does not require radiation or an oscillating charge to be present?

For most scientists, the answer is probably that there is an independent way for the gravitational field to get generated without the presence of the electromagnetic field. And they even rely on the structure of the unified field equations to highlight this alleged independence of the gravitational field from the electromagnetic field, as Dr Leopold Infeld did when he said:

"A pure gravitational field can exist without an electromagnetic field. But a pure electromagnetic field cannot exist without a gravitational field."

However, our research indicates there is no separation of the two fields. If one exists, the other field must also exist, and vice versa.

Furthermore, we are noticing how physicists are also assuming the gravitational field is a real and distinct force of nature. But what if the gravitational field never really existed? Rather, it is only the electromagnetic field that is doing all the work. Is it possible we live in an electromagnetic universe controlled by the electromagnetic field and nothing else?

That is the question the scientific community should be asking.

### What observational evidence is there to support a gravitational field in radiation?

Basically any solid matter that scientists think is uncharged is able to move when radiation hits it, or it emits the radiation causing a recoiling of the matter. A classic example would have to be the radiometer. This is a well-known device for which many scientists assume no charges are applied to it, and yet it is patently clear to scientists how the radiation from the Sun can move the so-called "uncharged" metal plates acting as "solar sails" and watch them spin on the tip of a fine needle.

In addition to this, Einstein saw from his General Theory of Relativity another important clue about the nature of light. Principally it is how light can bend in a gravitational field, much like a tennis ball thrown through the air can bend its path by the gravitational field of the Earth. In other words, the gravitational field of the tennis ball is interacting with the gravitational field of the Earth to cause the ball (and the Earth) to move toward each other. The only way to explain this bending of the light is for the radiation to generate its own gravitational field and interact with the gravitational field of the Earth (or any other body that generates a gravitational field). There is no other explanation. No physicist can say there is a difference in the way a tennis ball and radiation bends in the gravitational field of, say, the Earth. One can only conclude that both observations are a "gravitational effect". Any bending of the path of light or a tennis ball is always assumed to be gravitational in nature. Therefore, we must have a gravitational field generated by light, or radiation.

As a result of his careful thinking, Einstein decided to encapsulate the electromagnetic field and the gravitational field into a highly complex mathematical structure known as the unified field equations. This was Einstein's way of saying to the world that he believed the two fields are related.

However, if we think about this link further, the question arises as to how to separate the two fields in reality to show whether one field can exist without the other. How can we be sure one field is not the source for creating the other field and vice versa? With further careful thought, one can actually show the two fields are one and the same thing, if physicists wanted to make the effort.

### Is there a difference between solid matter and the unified field?

From Einstein's perspective, there is none. When radiation creates a gravitational field of its own and interacts with other matter, it behaves just like ordinary solid matter. It does not matter the fact that radiation contains an oscillating magnetic and electric fields. When radiation is analysed for its particle-like properties (known as photons) during its interaction with solid matter and compared to how a gravitational field is meant to interact with the same matter, Einstein found no difference between an oscillating electromagnetic field and a gravitational field, and similarly between an oscillating electromagnetic field and solid matter. Everything is seen as one and the same thing.

The only question for Einstein was whether radiation is the gravitational field. This is the sixty-four million dollar question. Or is there another way to generate a gravitational field without ever needing to use an electromagnetic field? Indeed, that was the only remaining question Einstein had in his mind in the latter part of his life after he published his Unified Field Theory in a German scientific journal in 1929. For if there was a way to show radiation is the gravitational field and nothing else can create it, then we can say we live in a purely electromagnetic universe. Then the only force of nature is the electromagnetic field (via radiation), and everything must have an electromagnetic explanation, including gravity and universal gravitation. It is as simple as that.

But if that is not true, then there must be more exotic things happening in the universe that physicists have to learn about. Perhaps an unseen exotic particle is creating the gravitational field? So far, there is no evidence to support this. No exotic particle alleged observed in particle accelerators can live long enough and have the means (and in sufficient quantities) to create a gravitational field all the time to explain how matter comes together on its own throughout the universe. If one had to poke a stick at any other energy capable of doing this with solid matter throughout the universe, you would have to choose radiation. It is ubiquitous. We live in an ocean of radiation, and there is no way of escaping it. The quantity is there. The question is how radiation interacts with solid matter and what imbalances in the electromagnetic force is taking place between two or more objects. If there is an imbalance in the force, could it be enough to account for the gravitational effect of matter clumping together?

That is where physicists will need to look at more closely.

### What areas of physics are likely to be challenged by Einstein's Unified Field Theory?

There are a number of areas, but our research indicates that physics will almost certainly face in the near future the following fallacies within its current body of knowledge:

- Gravity and universal gravitation is a separate and distinct force of nature.
- The neutron is uncharged at all times.
- There are exotic forces of nature known as the "weak" and "strong" nuclear forces.
- There are uncharged objects in the universe.
- Radiation cannot exert a strong enough force on solid "uncharged" matter for any practical purposes on a large-scale.

Looking at the Unified Field Theory and the way the universe works from observations, it is looking strongly like the following is closer to the truth:

- There is no difference between gravity/universal gravitation and radiation. Gravity and universal gravitation is controlled by radiation, and radiation is gravity/universal gravitation. So why bother having a gravitational field if radiation can do all the work of the gravitational field? The universe should be seen in a purely electromagnetic way with radiation applying the necessary pressure needed to keep things on the surface of planets as well as other objects moving around planets, stars and galaxies.
- The neutron is constantly charged. It is controlled by the two fundamental charged particles of the electron and proton spinning around each other to give the impression to an outside observer that the neutron is uncharged.
- Only the electromagnetic field controls how protons stay together and how the electron comes out of the neutron. There are no exotic forces of nature to consider.
- No matter how much we like to think or believe after measuring something and observing the results with our eyes, there is no such thing as a perfectly uncharged object at all times. We cannot trust what we see with our eyes or instruments all the time to think that we have the truth. We have to use our imagination to go beyond what our eyes are observing and to use computer modelling to confirm the new picture. Therefore, an atom with equal numbers of electrons and protons cannot be considered totally and consistently uncharged at every instant in time. The same is true of the neutron. Indeed, not even radiation can be considered truly uncharged at all times. Its oscillation ensures it remains continuously charged as well.
- Radiation is only moving the charged component of matter.

There will be other areas for radiation to play an important role. Quantum theory and the mathematical interpretations physicists have made of certain solutions is just one area. The mystery of dark energy and dark matter will also have an answer. The age and size of the universe is another area to be affected by the Unified Field Theory. And so too is the mystery of why our bodies age over time.

And dare we say it, there is also a new understanding of the concept of God in religion thanks to the properties of light?

There is much we can learn about light and its impact on many things in our lives and through the universe. It is time we take serious note of this situation.
