Hi, new here.
This came up briefly elsewhere and we didn't have the cerebral fire power to get very far with it.
Consider very, very long wavelength photons, (or conversely, very very low energy photons) produced inside the sun. Wavelengths we are looking at are in the range of 1 light year up 13 billion light years or so, the maximum size wavelength possible in our universe in this era. (or would that 'other' number apply?)
Do these photons escape from inside the sun? Considering the difficulty in making an antenna for these wavelengths (there are rather large), we think the sun is essentially transparent to this radiation.
We were also looking at the power output of the sun at these wavelengths, the individual photons are of vanishingly low energy, but, conversely, there might be quit a few of them.
We were looking at some solar luminosity formula, but one of the terms was for surface area of the sun, if the entire mass of the sun radiates at these wavelengths, is the surface area of the sun important in calculating the power emitted?
And if this all physics 101 topics, my apologies.
