fermion rotates through 720 degrees

If two spin 1 photons are put together so that the tips of their magnetic field vectors just touch one another ( the vector lines are all in the same plane), a particle results which looks the same when it is rotated through 180 degrees - a spin 2 particle.This is the spin a graviton is supposed to have.
Is this a graviton?
If a fermion has a finite number of electric field vectors pointing in all directions from the surface of a sphere, and it also has field vectors for the gravitational field, then the fact that a fermion has to be rotated through 720 degrees to look the same can be explained.As the electric field vectors rotate, the gravitational field vectors rotate through half the angle they do -
because the rotating electric field vectors generate a force which inhibits the rotation of the gravitational field vectors.

If we write these in vector notations, it will seem like the gravity vector is the different of two vectors:

$$V^{-}_G = V_s - V_t$$

where $V_s$ is the spacelike vector and $V_t$ is the timelike vector. The spacelike vector is related to the electric vector and the timelike vector is related to the magnetic vector. Now, if the angle between space-vector and time-vector varies from 0 to 360 deg, spin can be defined.

The above vector difference is the usual gravity vector but the antigravity vector can be given by:

$$V^{+}_G = V_t - V_s$$

To answer the question, it is important to understand the concept of spin in particle physics. Spin is a fundamental property of particles that describes their intrinsic angular momentum. Photons, being spin 1 particles, have a fixed orientation of their magnetic field vectors and do not change when rotated. However, when two spin 1 photons are put together in a specific configuration, they can form a spin 2 particle, which is the proposed spin of a graviton.

As for the fermion rotating through 720 degrees, this is a result of the spin-statistics theorem in quantum mechanics. It states that particles with half-integer spin (such as fermions) must be rotated through 720 degrees to return to their original state, while particles with integer spin (such as photons) only need to be rotated through 360 degrees. This is a fundamental property of fermions and is not related to the number of electric field vectors or the gravitational field.

In summary, while the concept of electric field vectors and spin can help explain the rotation of fermions, it is not directly related to the spin of a graviton. The spin of a graviton is a theoretical concept and has not yet been confirmed experimentally.
