Re:Observing the Unobservable (Score 1)

So the tracking system in the Mid-East, which found out where airplanes were by discovering where cellphone signals *weren't* transiting, proves that that point in space doesn't really exist, as it couldn't be observed? It seems to me that as much can be learned from what we don't observe but expect to, as can be learned from what we do observe. What is observed about these "non points" in space where the black holes exist is that there is a location in space-time that does not conform to our laws of physics if indeed there is nothing there.
