comment Dipole Moment of Collection of Harmonic Oscillators
Are the oscillators coupled? If not, what can you do? Look up "rotating wave approximation". Good luck.

comment How can a metal heated at 600° emit thermal photons at 4000°+?
Bobie, I think you are confused with temperature itself. Please, have a look in some references to understand its relation to certain distributions.

comment Could Legolas actually see that far?
Who says Legolas sees light? Maybe there is an "elve gauge field" he can "see". Who knows... If he can also see the past it's probably just gravitational waves.
