Sonic boom doesn't explain what causes sound only how it piles up.
Similarily I don't see how it explains the glow. Photons get generated regardless of whether they pile up or not. It's a consequence of particles bumping into atoms not the whatever speed of light might be in this medium.

How is piling up important?
