What would a black dwarf be like?

    What would a white dwarf be like after a long enough time that it had cooled to 70 degrees F and emitted no visible light?

    I think you've covered it, actually. It would be pretty cold and wouldn't emit much light. It would just be a dense, spinning ball. Occasionally something might crash into it, and get squished to a pulp. Pretty boring to a first approximation.

    A giant charcoal briquette is the best description I heard.
