Light can be emitted from the atom but light is not part of the atom. Electron can be emitted from the atom but electron is not part of the atom.
The Schwarzschild metric, based on Albert Einstein's theory of gravitation, is not compatible with the data from NASA.
The planetary geodesic from Schwarzschild metric consists of two orbits connected at the perihelion. The outer orbit between the perihelion and the aphelion is similar to an ellipse. The inner orbit between the perihelion and the Schwarzschild radius penetrates the interior of the Sun.
The geodesic coincides with the problem of non-zero energy tensor for the equatorial geodesic.
