Newton wasn't wrong! His theory of gravity allowed us to understand and predict LOTS of things. His theory was just incomplete, such as not takng into account the curvature of space.

Correct, no scientific theory is right or wrong. It's always in danger of being disproved if its predictions disagree with observation. As happened to Newton's law of gravity, but that doesn't mean it's useless, for most practical purposes it's still used today.

Doesn't sound like they're going to disprove - the red color tending to agree with his predictions. It would certainly be interesting if we learned something about what happens when relativity breaks down though.
I never studied Einsteins field equations, it's out of my depth. But if I understand aright from the shallows, it takes a crazy amount of mass to bend space into a black hole. There's nothing else in it, that I can understand, that would make any applications of 'bending space/time' possible, say on a pocket or apartment scale. So if there are interesting technical possibilities, I just don't grasp them.
