As a particular volume expands, mass energy density is changed only by the increase in volume, but the energy density of radiation is changed both by the increase in volume and by the increase in the wavelength of the photons that make it up.
Because fusion yields about 0.3–0.9% of the mass of the nuclear fuel as released energy, it is energetically more favorable than fission, which releases
Because fusion yields about 1% of the mass of the nuclear fuel as released energy, it is energetically more favorable than fission, which releases only about 0.1% of the fuel's mass-energy.
For example, the total mass-energy content of the neutral pion is converted into gammas, not just its rest mass.
Causal notions appear in the context of the flow of mass-energy.
Most of the mass-energy of a common proton or neutron is in the form of the strong force field energy ; the individual quarks provide only about 1% of the mass-energy of a proton.
