On 29 November 1935, physicist Erwin Schrödinger introduced the world to his now-famous thought experiment, "Schrödinger's Cat," a perplexing illustration that highlighted the philosophical dilemmas of the Copenhagen interpretation of quantum mechanics.
The hypothetical scenario involves a cat placed inside a sealed box with a radioactive atom, a Geiger counter, and a vial of poison, set to be released if the atom decays. Until observed, the cat is paradoxically both alive and dead, embodying a superposition of states.
This paradox underscores the troubling implications of quantum mechanics, where particles exist in multiple states until measured, challenging classical notions of reality and observation.
