Answer to Question 1

The geometry of space is warped or curved near a black hole. The gravitational field is so overwhelmingly large that the curvature of space is extreme, so extreme that space folds over on itself at the event horizon. Further away from the black hole, gravity from it is weaker and the curvature of space is less.
