If a tree falls in the forest and there's no one around to hear it, does it make a sound? The obvious answer is yes—a tree falling makes a sound whether or not we hear it—but certain experts in quantum mechanics argue that without an observer, all possible realities exist. That means that the tree both falls and doesn't fall, makes a sound and is silent, and all other possibilities therein. This was the crux of the debate between Niels Bohr and Albert Einstein. Learn more about it in the video below.
