Thought experiment
A thought experiment is a hypothetical situation in which a hypothesis, theory,[a] or principle is laid out for the purpose of thinking through its consequences. The concept is also referred to using the German-language term Gedankenexperiment within the work of the physicist Ernst Mach[2] and includes thoughts about what may have occurred if a different course of action were taken.[3][4] The importance of this ability is that it allows the experimenter to imagine what may occur in the future, as well as the implications of alternate courses of action.[5][6]
