Hole Argument

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.

Famous quotes containing the words hole and/or argument:

    I see the horses and the sad streets
    Of my childhood in an agate eye
    Roving, under the clean sheets,

    A striking feature of moral and political argument in the modern world is the extent to which it is innovators, radicals, and revolutionaries who revive old doctrines, while their conservative and reactionary opponents are the inventors of new ones.
    Alasdair Chalmers MacIntyre (b. 1929)
