Man of Honour
Problem is looking at it 2d in photo, is it a sphere of nothingness that sucks everything into or a disc or is it a 4 dimensional object ?
It depends what you mean by "black hole" and 4 dimensions. If it's the volume of space contained within the event horizon, it's a sphere in 3D and in 4D if you're counting time as the 4th dimension. If it's the actual thing itself, nobody knows what it is let alone what shape it is or if it has a shape. "singularity" may as well be short for "haven't got a single idea"
