When i was reading a book on topic particle physics, it is written there that neutrinos are always moving in the neutrino's negative of direction of spin. But it is written there only neutrinos have that kind of a behaviour among all particles not any other particles. In time, when i first undestood that elementary particles are ring vortices, i remembered this property of neutrino was written in a book called "uzayın sırları"(secrets of space). Immediately i explained this phenomena since fast moving particles are feeling a strong magnetic field around them, surely they must align them. But at that time there was a huge problem, since according to ring vortex theory of particle physics, all leptons together with protons and neutrons have magnetic field around them, and they all have electrostatic attraction and repulsion. But quantum of charge doesnt exist in that theory for example neutrinos have much smaller charge than electrons. But the book i read was written by a person really know too much about particle physics therefore there was a probability for experimental data's contradicting with ring vortex theory. But i didn't give probability to it. Since it was so clear that existence of helicity at one particle was a strong evidence of ring vortex theory. I became quite self confident, but i didn't searched for data since writer of the book gave me an impression of helicity's being only known for neutrinos, i took an impression that is no other particles have property like it. Thats why i tried to exemine directions. First of all  spin direction of particles in every theory before ring vortex theory , for exapmle classical theories, is accepted by me as same as the fluid direciton of motion inside ring vortices in ring vortex theory.  If anything contradicts with that phenomena, i accepted that ring vortex theory was the false one.  I was so sure that all before theories predicted spin and spin direction true, this point was not arguable for me. 
                                          First of all helicity is nothing  to do with direction of spin , it is only related with direction of magnetic field of the particle according to simple ring vortex theory of particle physics. The reasoning is obvious, every particle has a magnetic field, secondly fast moving particles will experience a relative strong magnetic field in the negative of their direction of motion since they are moving inside a sea. That strong magnetic field is not there for a stationary observer, it doesn't exist for them. Since we accepted that classical spin direcitons are true, we thought a classical electron, a charged sphere spinning in anticlockwise direction. Since i learned that neutrino's spin direction is negative of its direction of velocity, then i understood that particles must have same direction of magnetic field and spin , while an antiparticle must have spin direction as opposite to their magnetic field direction. To evaluate ring vortex theory, i took an anticlockwise spinning electron, using righthand rule i decided its magnetic field direction. Than using left hand rule i decided spin direction of the electron. But i made many mistakes doing these simple things, and during a week , ring vortex theory was seemed to be false, since i resulted in that particles have antiparticle helicity, and antiparticles have particle helicity. I even thought that ring vortex theory is entirely false unusulally, like a voyager while seeking a north pole finding the south pole. It was a reverse truth. IT was the falsest theory possible, theory was saying reverse truth.  But in time i understood that i made a simple mistake, misremembering current direction, taking current as direction of motion of negative charges. Than everything became okey. A lepton must have same classical spin direction and north magnetic field direction, an antilepton must have a spin direction which is negative of the direction of their north magnetic field. 
                                     Lately i learned that name of this property of neutrinos is helicity, and i had opportunity to search for helicity for all leptons is known or not. Not knowing the name "helicity" i couldn't search it in the internet. There was a low probability for possible helicity of other particle's being known. This was a point to falsify or confirm the ring vortex theory. Furthermore if helicity of other leptons are known, than it must be exactly how i predicted. If so then ring vortex theory is confirmed, if not then ring vortex theory is falsified. Then i searched for it in the internet, especially i searched wikipedia. Surprisingly i learned that all leptons have helicity. And all helicities are defined giving names "rright handed" and "left handed" . But all helicies are exatly how i predicted. Therefore i dont know this was an experimental data or not, but if it is experimental data than ring vortex theory is confirmed. 
                                      But scientist are thinking that since they didnt realise charge of a neutrino, a neutrino maybe antiparticle of itself. This is not true all neutrinos have charge and magnetic field. The reason why magnetic field of earth penetrates neutrinos is very simple, the fast moving(near speed of light) neurtino is seeing earths magnetic field in entirely different direction , it doesnt need to align weak earth's magnetic field since it is already aligned to a magnetic field whihe has almost highest possible magnetic field strenght(If speed of light cannot be exceeden by that liquid or more precisely if relative velocity of the liquid with respect to neutrino cannot exceed speed of light). IF neutrinos were slower like an electron in solar wind, it would align the earth's magnetic field and cannot reach the earth. 
                                       Secondly,  we dont need to give name helicity to helicity, it is simply alignement of particle if there is a strong enough magnetic field. If space liquid and given particle is moving in the same direction with same velocity, independent of how fast they are together, helicity will not exist and particle will not align in any direction.
                                       Helicity is not unique for particle, a dipolar magnet for example will have helicity. If they can reach enough velocity in any direction, practically their nort magnetic field direction will look backward, and their south pole will look at their direction of motion. 
                                         Another clear point is that, if a living thing for example an ape move away from earth inside a spaceship and reaches high enough velocity in any direction, since there will be stong magnetic field backwards relatively, the living thing will die. Fast spaceships must use magnetic shields. Even superconductors cannot do that much shielding since at that much high magnetic fields, superconducting state cannot continue.
