What he says at 10:30 is very interesting. He refers to Corinthians chapter 15:41, which says that "there is one glory of the sun, and another glory of the moon, and another glory of the stars."

I looked up that chapter in the Douay-Rheims online version, and indeed, it does appear to refer to the sun and moon and stars as being separate glories (lights?).

I'll post a few more verses, so as to put into better context:

Corinthians 15: 39-41:

[39] All flesh is not the same flesh: but one is the flesh of men, another of beasts, another of birds, another of fishes. [40] And there are bodies celestial and bodies terrestrial: but, one is the glory of the celestial and another of the terrestrial.
[41] One is the glory of the sun, another the glory of the moon, and another the glory of the stars. For star differeth from star in glory.

I'd vote if there were an option "absorbs and re-emits".

That's a good point.  I think that would be my guess too.
