    Part of a larger discussion

    Challenges→The canonical formulation of general relativity yields 10 scalar equations, four of which are constraints and six are genuine evolutionary equations.

    As Earman and Norton argued, hole argument considerations show that no set of equations in GR uniquely evolves spacetime, collapsing the constraint/evolution distinction ontologically.

    Key Terms

    Collapsing (in this context)(in mathematical structures)
    Taking multiple separate things and combining them into a single unified structure, rather than keeping them distinct.
    Constraint/evolution distinction(as a technical distinction in physics)
    The difference between rules that must always be satisfied (constraints) and rules that describe how things change over time (evolution).
    Earman and Norton(as the authors being referenced)
    Two philosophers (John Earman and John D. Norton) who wrote influential papers about 'supertasks'—thought experiments involving infinite sequences of actions happening in finite time.
    Equations in GR(as technical formulas)
    Mathematical formulas in Einstein's theory that describe how gravity and spacetime behave.

    Start fresh with something unrelated.
    (as an abbreviation in physics)
    Short for General Relativity, Einstein's theory of gravity that describes how space, time, and massive objects interact.
    Uniquely evolves spacetime(as describing predictability)
    Determines one single way that space and time must change over the future; without this, you can't predict what spacetime will look like next.
    hole argument(Later recognized by Einstein himself in 1915 to be based on a false premise)
    Einstein's 1913 argument that generally covariant field equations permit two different solutions in a matter-free and energy-free region of spacetime (a 'hole'), where the two solutions assign different values of the metric tensor to the same spacetime point, allegedly violating univocalness
    ontologically(contrasted with semantically in the statement)
    Relating to what actually exists or is real, rather than just what words mean or how we talk about things.
