This is an idea that replaces the superstrings etc.
Still working on it.
The basis for the theory is that an electron is not a particle and not a wave. Therefore we need to figure out what it is, so we can learn better how things work.
After seeing a scientific movie about vortices in superconductive materials, it occured to me that these behave very similar to atomic particles. Except these vortices behave as if they are 2D particles.
So I simply added one dimension.
Particle is then a a 4D vortex that is a connection between two 3D spaces. The particle can be a true sphere, even when it contains other particles, like quarks.
The spaces can contain waves, which makes EM waves possible. Photons do not bounce with each other, but behave much like waves. They only appear as particles or quanta in interaction with electrons.
So I assume that the EM-field is a 3D space. It may actually be a 4D or 5D space if we look at it closer, but to keep it easy I'll leave it 3D for now.
I assume that the proton and the electron are both vortices but are connecting to two different 3D spaces. Together they can build a 3D sphere structure, where the spheres are inside each other. This way an atom is a spherical structure, like we see in atomic force scanners, and the electrons seem in orbit around the protons.
Everything seems to become much easier, the more we try to put it in practice. Just like a good theory should work. For instance an anti-electron is simply a vortex that is spinning in the other direction.
Unlike string-theory, this 4D vortex theory can give predictions.
Assuming spheres are the normal configuration for electrons, we might see that this is for each band of electrons. In quantum-physics, they assume a whole layer or cloud of electrons in a superstate, while there are only a few.
In practice, we don't see clouds. The superstate might arise from the group of vortices/spheres being in a certain state.
Electrons connect different spaces than Protons, so electrons should not be able to break through protons. And maybe it does so when they hit a neutron. Neutrons may contain an electron.
The interaction with neutrons can be measured with anti-electrons. Things may look different when we assume them to reside in different 3D spaces. Maybe nuclear physics becomes clearer.
