In general relativity, the hole argument is an apparent paradox that much troubled Albert Einstein while developing his famous field equation.
Some philosophers of physics take the argument to raise a problem for manifold substantialism, a doctrine that the manifold of events in spacetime are a "substance" which exists independently of the matter within it. Other philosophers and physicists disagree with this interpretation, and view the argument as a confusion about gauge invariance and gauge fixing instead.
