Analysis of nuclear fusion exists inside earth

Using the falsification method, it is proved that "There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements" is a false proposition, it is inferred that the source of heat in the deep earth must have an unknown exothermic factor, and this exothermic factor is the heat from intermolecular nuclear fusion. Then, using the quantum tunneling effect of proton and the observed continental plate drift facts, it is determined that there must be nuclear fusion inside the earth. Through the diagram of temperature of planet Earth, it can be determined that the endothermic nuclear fusion reaction occurs in the core of the earth, and because the water becomes solid and cannot ionize hydrogen ions, nuclear fusion cannot occur, so as to determine that the temperature at Earth's center is the freezing point of the saline solution at the center of the earth's core.
