the core of the sun to reach the surface of the sun and be radiated
It seems that the energy released by a nuclear fusion in the sun's
core would not be transferred as light because light can be emitted
only by valence electrons being bumped into an elevated state then
falling back to their stable state, emitting a photon in the process.
The initial energy released by a nuclear fusion in the core of the sun
must travel by physical collisions and transfer of momentum from
particle to particle, gradually making it to the solar surface where
atoms with valence electrons exist, then this energy can take the form
of light and be radiated into space.
