Tech-nic-ally, at least in terms of black holes, "invisible" refers to the fact that as far as seeing something due to visible, reflected light, you cannot "see" a black hole because light gets sucked in along with anything else that gets near it.
In that case, what's behind it is…the other side of the black hole.
what does invisible mean? if it means see-through, then what's behind it?
