  "abstract": "We construct a simple Lagrangian from the scale factor of the Universe, which gives the Friedmann equations for a closed, homogeneous, and isotropic Universe. If the Universe was formed in the interior of a black hole, then the constant energy of the Universe is related to the mass of the black hole. We apply Schwinger's variational principle to this Lagrangian and show that, for a supermassive black hole, it may be the origin of the observed order of magnitude of the temperature fluctuations in the cosmic microwave background.",
