The Single Field Theory
"The development during the present century is characterized by two theoretical systems essentially independent of each other: the theory of relativity and the quantum theory. The two systems do not directly contradict each other; but they seem little adapted to fusion into one unified theory. For the time being we have to admit that we do not possess any general theoretical basis for physics which can be regarded as its logical foundation."
Albert Einstein, 1940
A Basic theory:
We do not possess, still today, any general theoretical basis for physics which can be regarded as its logical foundation!
In the standard model particles are considered points which move through space. To take into account the different particles interactions we have to provide not only position and velocity, but also things such as mass, electric charge, colour or spin. The wave equations give us answers that are in good agreement with observation once they have been properly manipulated. An equation that gives a correct answer may be useful, but unless it also answers many of the deepest how and why questions, it’s inadequate.
The gravitational field at a fixed time could be described by the geometry of the three spatial dimensions at that time. The history of the gravitational field is described by the four dimensional space-time that these three spatial dimensions sweep out in time. Space-time is a dynamical field. To describe a dynamical field (space-time) it’s required a theory of quantum gravity, an appropriate description of physical processes that occur at very small length scales and short times. The standard model does not seem to fit into this scheme. The Single Field Theory (SFT) physically outlines intuitive concepts using a novel theoretical framework into the local electromagnetic interaction in the nanometric subsystem composed of electrons and photons. The SFT formulate a new conceptual idea about light-matter interaction.
The particle is replaced by a single fundamental building block, a resonant electromagnetic wave. Different resonant electromagnetic waves represent the different particle types, since different modes are seen as different masses or spins. We can make sense of ''the interaction phenomenon in the SFT in a way we could not in the standard model. The SFT gives a consistent theory of quantum gravity, which possesses the necessary freedom degrees to describe all the particle interactions. Gravity is not a thing we put in the theory, it must be there. A great achievement of the SFT is to give a consistent theory of quantum gravity, which resembles Relativity, Special and General ones.
