Thread: Gaping hole could be a black hole scar?

I'm not sure if this was mentioned yet, but could that giant blank space astronomers found be the scar of a now gone black hole?

Or a still existing supermassive black hole. Just because it's no longer visible by the matter it's sucking in (none left to suck in!), doesn't mean it's gone.

Finding a lonely black hole would require a thorughful scan of the sector, looking for a gravity lens effect around the edge of the event horizon.
