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 energy tensors of the metrics from four vacuum solutions of general relativity are calculated for each metric. The calculation shows that most of the energy tensors and the contra tensors are not zero for vacuum.Â
The four metrics are Schwarzschild metric, Reissner–Nordström metric, Kerr metric and Newman metric.
