Nice work William, that is beautiful and inspiring!

I have to be a punk and point out that the Milky Way isn't 'passing over' us, we're the ones spinning within it.

It's really important to make that mental shift into spherical space. Try observing the sun and forcing your brain to see it staying in place in the sky; make your mind see how the earth has to move in order to align the horizons with the sun at dawn and dusk. It's quite dramatic when you get it.
