*It makes no difference how the energy is produced, according to the Second
Law Of Thermodynamics if you make a vast amount of energy then you're going
to make a vast amount of waste energy in the form of infrared radiation,
and to us that will look like a very intense point source. But we have seen
nothing that looks like that. *
