" A famous thought experiment by physicist Erwin Schrödinger points out the kinds of odd occurrences that are made possible by quantum physics. Imagine that you have a closed box that contains a wave-particle, a cat, a lever, and a bowl of cat food with a loose lid. If the wave-particle becomes a particle, it will trip the lever, which will flip the lid off the bowl of food, and the cat will eat. If the wave-particle becomes a wave, the lid stays on the food. If we open the box (thereby making an observation), we will see either an empty bowl of cat food (and a happy cat) or a full bowl (and a hungry cat). It all depends on the type of observation we make. Now here’s the part that boggles the mind: Before we look in the box and make an observation, the bowl is both empty and full, and the cat is simultaneously fed and hungry. At that moment, both possibilities exist at the same time. It is the observation alone that turns possibility into reality. "
