"If a tree falls in a forest" is a philosophical thought experiment that explores the nature of observation, perception, and reality. The classic formulation of the question is: "If a tree falls in a forest and no one is around to hear it, does it make a sound?" This scenario raises issues about whether sound exists if there is no one to perceive it.
