A thought experiment is an experiment that takes place in the mind of a scientist. Unlike with a real-life experiment where change is actually seen and perhaps measured, thought experiments are done just to show a special way of thinking. Anyone can do a thought experiment. All you need is your mind because all the steps take place in your mind.
The usual goal of a thought experiment is to explore the consequences of the principle in question. Like so: if this were true, what would follow from it?
