Analysis of the "neutrino" problem has shown that the proton is obtained not in quantum fairy tales, but in reality, as a result of the collision of a neutron with a photon, electron-anti-electron dipole. This understanding of the transformation of a free neutron into a proton dispenses with the use of a fantastic “neutrino” that does not exist in the material World, revealing the real reasons for seventy years of experimental failures in the “neutrino” problem. Analysis of the "thermonuclear" problem has shown that the quantum understanding of nuclear fusion in the Sun and in the "hydrogen" bomb with the release of huge "thermonuclear" energy is wrong. Therefore, this understanding of productive fusion reactions, taken as the basis for the operation of controlled power reactors on light nuclei, led to fruitless experimental attempts in the "thermonuclear" problem. Analysis of the "neutrino" problem made it possible to understand that real "cold" nuclear fusion really exists. It does not need to overcome the electrical barrier, since such a barrier does not exist in "cold" fusion. The magnetic barrier, in comparison with "hot" fusion, is as ridiculous as 13.65keV. "Cold" fusion is sequential neutron-photon fusion. Using the example of a "hydrogen" bomb, the productive work of "cold" fusion from a "thermonuclear" charge of a "hydrogen" bomb of unstable, instantly decaying, with the release of "thermonuclear" energy, 5Li and 8Ве nuclei is described.
