    And it has a density of only about 3g per cubic meter. It’s not much denser than a vacuum made with a mechanical pump.

        Not really. If more material falls in, its mass and size increases (the volume increases faster than the mass, which is why it’s so unexpectedly low density in the first place), but otherwise it just sort of sits there.

        Over the very long term, it will evaporate away by Hawking radiation. But that’s a very very slow process. Like, long after everything else in the universe has ended.
