If you want to reproduce the image
used as a thumbnail, get some wire wool and a 9V battery, a metal whisk on a chain and a camera on a tripod.
Put the wire wool into the whisk, touch the 9V battery to the wool and is starts glowing, spin it around your head and it burns and bits fly off.
Take a long exposure photo of that.
It's not a black hole.
