The Sunspot's only importance is as a guide to WHERE these flares will come from, and when. So.... the FLARES are the THING we worry about, and the SUNSPOTS are just the SIGNAL for the FLARES.
Now, A black hole is not A THING, but a SIGNAL of an event. Energy and matter are sucked into it. There is a 'ring' of high energy surrounding the 'black hole'. Yes, a black hole has a huge gravitational potential energy. But we really don't know what causes that huge gravitational energy. Nor do we even understand how GRAVITY is created.
So, like a SUNSPOT, the BLACK HOLE is not a physical object, but only an indicator of a huge 'change' in energy density. The 'event horizon' and surrounding matter are real. Energy and mass pass through the black hole and GO somewhere. In order to 'pass through', then the black hole itself is not something that is there, but more of something that is not. It is because there is NOTHING inside the perimeter of the event horizon (besides the energy and mass being pulled into the HOLE) that leaves an EMPTY HOLE for the matter and energy to pass through.
Think of it this way. A black hole is like a whirlpool in a large body of water.
The EMPTY CONE SHAPED AREA is CAUSED by the energy/matter being subject to a huge gravitational potential energy (like a large HOLE in the bottom of the lake, or a built in FLOOD OUTLET for a DAM.

So... the KEY is what causes this HUGE CHANGE or IMBALANCE in the POTENTIAL GRAVITATIONAL ENERGY FIELD, and not the HOLE ITSELF. IT's just a HOLE.
It's even called a HOLE.
If you get the chance, ask some PHYSICS major if a thing called WHITE HOLES, exists. It would be interesting to hear what they would say.
A hole can't be white, it must be black, and either empty, or passing matter/energy completely 'through', or it isn't technically even a 'hole'.
All I have to say about that is......... HUH?
