Why do stars twinkle?

Ever wonder why stars look like they're dancin' when they're actually just sittin' there? It all starts at the Star Source, which is actually pumpin' out a perfectly STEADY beam of light into the cosmos. That light speeds along a Space Path, travelin' through a vacuum where there's absolutely nothin' to get in its way or slow it down. But then, it hits our atmosphere's Air Layers—a thick, messy soup of turbulent, movin' gases that's constantly shiftin' around. As that light hits those movin' gases, we get Light Refraction, where the beam is BENT and knocked off course like it's hittin' a bumpy road. Because that bendin' happens so fast, your eyes see a Perceived Twinkle, which is really just the star's light jumpin' positions in a fraction of a second. It's basically a cosmic game of telephone!
