Can someone answer this question: the simulation says look for warps near other big bright things - then what about black holes?
We can't see black holes, but they certainly have the potential to bend light/become a lens. According to Spacewarps guide, lenses are only found around other visible objects; an arc around what seems to be nothing doesn't qualify. What about those black holes?

Good question, we're talking about this here: http://talk.spacewarps.org/#/boards/BSW0000004/discussions/DSW00000cp
I think black hole lensing is probably too rare for us to have any chance of detecting it.
