    A black hole is an object so dense and heavy, even light can’t escape its gravity. Black holes appear when a star collapses and reaches the required density.

      Yeah I get that. But the video was saying a black hole the diameter of the solar system has an average density inside the event horizon of air. I was wondering if you need to compress it any, or if a solar system sized volume of air would already be a black hole, or would it need to collapse to a singularity first?

        If the volume of air is big enough, it will be so heavy that it will act as a black hole. It doesn’t need to collapse first, although it probably will because of its own weight.
