The eternal physics family feud captured in one shirt! For 100+ years, quantum physics and general relativity have been like siblings forced to share a bedroom—they fundamentally disagree on how the universe works at its core. Quantum mechanics handles the tiny subatomic world with probabilistic chaos, while relativity elegantly describes gravity and spacetime at cosmic scales. Despite thousands of physicists playing marriage counselor, we still haven't found a unified theory that makes both sides happy. String theory? Loop quantum gravity? Extra dimensions? The honeymoon phase never arrived. Meanwhile, experimental physicists are in the corner muttering "just give me something I can actually test in a lab, please."
