The ultimate demonstration of frame of reference! In the first panel, a blue car approaches the observer. In the second panel, a red car drives away. But wait—it's the same car! The meme brilliantly illustrates the Doppler effect: light waves compress (blue-shift) when approaching and stretch (red-shift) when receding. This is exactly how astronomers determine if galaxies are moving toward or away from us. Your brain just witnessed cosmic principles in a driveway cartoon!
