Introduction:

Our technology works with electric energy obtained directly from the Sun (photovoltaic energy) or from water (hydroelectric energy). Electric energy is also obtained from thermal generating stations (carbon, fuel-oil, nuclear…) or from chemical batteries.

Never has been possible to distinguish electric energy depending of its origin.

Therefore, if we can always obtain electric energy and it is undistinguishable, we can think that all energy forms are the same energy.

The aim of this paper is to discuss about this idea.

Theoretical analysis:

We are going to analyze the identity of energy fields which Official Science considers as different forces: Gravitational, Electromagnetic , Strong and Weak Force.

In order to understand the identity among electromagnetic and gravitational fields we are going to remember gyro magnetic fields:

1. Barnet Effect :
   Bodies rotating with uniform angular velocities become magnetized.
2. Einstein-de Haas Effect:
   Bodies hanging up freely begin to rotate when they magnetized.
3. Stewart-Tolmann Effect:
   Voltage appears inside rings which rotate with no-uniform velocity. Therefore an electric current is measured.
4. Bodies subjected to external forces and consequently subjected to accelerations, show electric fields presence because it is possible to measure electric currents inside bodies.
   From these observations ,we can conclude that magnetic fields is synonymous of rotation and electric fields is synonymous of linear accelerations. For example, big bodies as planets, stars, galaxies, etc have a magnetic field associated because they are rotating around its axis. Of course, intensity and direction of magnetic field depends of body composition, size and geometry.

In similar form, little bodies or very little bodies ( free particles) have a magnetic field associated because they have to rotate to be stable.

Also compressive stresses on matter are synonymous of electric fields and tensile stresses are synonymous of magnetic fields because electric currents are measured .For example, we can just remember the so-named electrostriction phenomena or currents measured in bars subjected to pure bending.

To complete our study we can not forget that

1. Electromagnetic and gravitational fields are central fields
2. Minkowski metrics of electromagnetic fields is an approximation of Schwarschild metrics when radium is very big.
3. Filkestein studied Schwarschild metrics .By means of a coordinates change he obtained solutions which can be analyzed:
   1. Positive and negative gravitational masses have been found in similar form to positive and negative electric charges.
   2. When radium of bodies is equal to Schwarschild radium (critical radium),then positive and negative gravitational masses also exist, however if we are very far of these masses, fields observed are negligible . That is to say ,we are speaking about neutral particles : They present strong interactions in spite of no-electromagnetic interaction is observed.

We conclude that electric charge of free particles (protons, electrons, muons….) is a very dense mass which any external observer always “sees “ with the same radium because of its size is lower than Schwarschild radium. That is to say, electric charge is a very dense and little mass creating very high intensity fields and it is always observed with the same radium.

Spin of particles is associated to rotation motion. For that reason, neutrino particle can not exist.

Finally we can comment some aspects of thermal energy concepts:

1. Temperature gradients generate electric currents. Therefore, thermal gradients are electric fields. For example, Thomson Effect assumes this assertion but if we speak about vectorial fields this conclusion is always valid .
2. When bodies are subjected to temperature scalar fields, electric currents conduction increases or reduces depending of material and thermal level inside solids. For example, high temperature plasmas of metals behaves very different of metals at room temperature.

Conclusion:

Electromagnetic fields ,compressive stresses fields, thermal radiation fields , gravitational fields, fields created by particles are of the same nature.

All energy forms are the same energy and, therefore, the Unified Field is a Central Field.
