    Part of a larger discussion

    Supports→The universe can be finite and unbounded at the same time, refuting the conflation of unboundedness with infinitude.

    Modern cosmological models (e.g., closed FLRW spacetimes) instantiate finite total volume with no spatial boundary, confirming the distinction is physically realizable and not merely formal.

    Key Terms

    Cosmological models(as used in physics and philosophy of science)
    Scientific theories that describe the structure, origin, and evolution of the universe as a whole.
    FLRW spacetime(as used in cosmology)
    A mathematical model used by physicists to describe a universe that looks roughly the same in all directions; named after four scientists (Friedmann, Lemaître, Robertson, and Walker) who developed it.
    Finite total volume(as used in cosmology)
    A universe that has a measurable, limited amount of space—like a container with an end, rather than infinite space.
    Merely formal(as used in philosophy)
    Something that exists only on paper or in abstract thinking, without any real-world application or existence.
    Physically realizable

    (as describing whether an intervention can actually be performed)
    Able to actually be done in practice given real-world constraints, even if it's theoretically possible in principle.
    Spatial boundary(as used in cosmology and geometry)
    An edge or outer limit where space ends; imagine the edge of a bubble that separates space from non-space.
    instantiate(as used in metaphysics)
    To be a concrete example of something, or to have and display a particular property or category.
