Document Summary
Quark 10^-16 cm | electron 10^-16 cm | proton 10^-13 cm | nucleus 10^-12 cm | atom . Fusion small nuclei stick together to form something new. Positron antimatter, has opposite charge of a proton. The greater the pressure the higher the temperature. In the radiative zone, energy gradually leaks out in the form of randomly bouncing photons. Convective zone takes energy through to the surface. Cells of gas will rise and emit energy and sink in the convective zone again. A much slower process than that of the radiative zone. The scientific method for astronomy is the following: observing -> creating mathematical models based on physics. For every nuclear fusion, two neutrinos are released. Early researchers only observed 1/3 of known neutrinos. Facilities were only detecting one type until a few years ago. Fluxations in the sun"s magnetic field could cause radiation to explode into space. Without the sun"s magnetic field, life on earth would not exist.
