One of them is that quantum mechanics allows for a single object to exist in two different states of reality at the same time. For example, quantum physics allows a body to be at two different locations in space simultaneously – or both dead and alive, as in the famous thought experiment of Schrödinger's cat. > The technical name for this phenomenon is superposition. Superpositions have been observed for tiny objects like single atoms. But clearly, we never see a superposition in our everyday lives. For example, we do not see a cup of coffee in two locations at the same time.
