Question: Are there any black holes in our solar system and if there are which is the largest and most powerful?

I don’t think there are any black holes within our solar system – not in space anyway. However, scientists have managed to create tiny artificial “black holes” in the lab this year. These “black holes” swallow sound instead of light, but they are nonetheless useful tools to study some of the things that have been proposed about real black holes.
