Title: Life of love of electron, life of love wave of proton, and size of universe
Inventor: KOBORI SHIZU
IPC: G99Z99/00
Filed: 2019-10-10
Abstract: To solve the problem that a Love wave of an electron has a revolution orbit of 1.749×10-9 m at -273 degrees, so that the revolution orbit never becomes larger, this means that the Love wave of the electron is inactivated and has its day, and how long are the Love wave of the electron and the Love wave of a proton emitted in Big bang lived?SOLUTION: In this day and age, for example, the surface temperature of the sun is 6,000 degrees. In this day and age, for example, the revolution orbit of a Love wave of an electron in the universe is 10-14 m. In this day and age, for example, an average surface temperature of Mars is -63 degrees, how large is the radius of the universe where the revolution orbit of the Love wave of the electron reaches 1.749×10-9 m? A general expression for solving that is considered. The universe is expanding with the time after emission in Big Bang. The Love wave of the electron expands until the revolution orbit reaches 1.749×10-9 m. At this time, how large is the radius of the universe?SELECTED DRAWING: Figure 1
