A question, if I may. That black hole has supposedly been there for eons. Howcum it is still hidden inside a cloud of haze. If EVERYTHING anywhere near a black hole gets sucked into it, never to return; howcum that hazy cloud is still there. A lot of what we’re being told, upon considdration, is beginning to sound like so much balderdash. These spectacular “finds” wouldn’t relate to research grants, would it?

Because our galaxy is incredibly big and there's plenty of room for dust that won't be pulled into this black hole - that dust happens to be between us and the galactic center.

The haze is the matter that queues up waiting to be sucked into the hole. Note space is not really truly empty vacuum, there’s dust plus deep space at its emptiness has approximately one hydrogen atom per cubic centimeter.
