Maybe a lunar Disney. Just wondering about your thoughts. See responses to previous questions. In my opinion, quite nicely. If Europa around Jupiter is found to have a healthy ocean of liquid water under a thick sheet of ice, it could be a very nice place to colonize eventually.
Water is the coin of the realm in space.
Having an ocean of it would be a major plus. The ice layer would protect the colonists from the Jovian radiation too. The only problem is the propulsion requirements to come to Earth would be greater than for the Mars transit. There is no formal relationship between antimatter and black holes. Some theories state that antimatter particles might be created near the event horizon of a black hole but this has not been verified.
