Quote from: JP on 16/11/2010 03:34:43Generally, the answer would be no. It would depend on what you wanted to do with "mass," but if you put the gas in a box and wanted to push the box, the apparent (inertial) mass of the box would be due to the rest/invariant masses of the particles plus a mass term resulting from the energies of the particles.So the real mass of the gas in the box is the sum of every particle's rest mass.If we put some mass in a box, and half of the mass turns into energy, then the mass in the box is halved. There is simple logic in this.My mass is 7 kg. Scientists have found out that mass of typical adult human being is about 7 kg. This is still new and uncertain stuff. And silly laypeople think they know their mass, and with good accuracy. []

Plasma inhabitants of Sirius B see increased frequency of photons from Sirius A. Frequency of these photons is increased in 1,00023 times.However they don't see increasing of energy of the photons.Then you should change the formula of photon energy. []
Then you should disprove this formula: v = v_0 /√[1-2GM/Rc²]v-frequency []

The observer will observe that said photons are mostly HIGH frequency photons.
