What Is Gravity? Nobody Actually Knows

This meme perfectly captures the existential crisis of theoretical physics! On the left, we've got the blissfully ignorant folks who don't even question gravity. In the middle, the textbook answer parrots who recite "gravity is spacetime curvature" without understanding it. Then on the right, the PhD physicist having a complete meltdown because despite what we tell undergrads, nobody actually knows what gravity fundamentally is! String theory, quantum gravity, loop quantum gravity—we've been chasing these theories for decades with minimal progress. The bell curve of understanding shows that true knowledge means recognizing how little we actually know. Next time someone confidently explains gravity to you, just remember there's a frustrated physicist somewhere screaming into the void about quantum fruit loops!
