Wait...
Did you say that the blue glow around Earth is due to something OTHER than the atmospheric gases? I find that hard to believe. I mean, the sky is blue because of Rayleigh scattering and looking at the atmosphere side-on the way you would if you looked at the edges Earth from space you'd see what looks like a blue glow because you're looking through a lot of atmosphere at that angle, just like you do when you're standing on the surface of the planet looking up at the sky during the day. I know this to be a scientifically proven fact soooooo...why the grid thing?
I've been a hardcore antitheist for a long time and these lessons have given me something to doubt my cynical views and that's a good thing. I'd hate to have a reason to see this stuff as just the same wash as all other religions.
