The concept of "going behind" a black hole can be a bit counterintuitive because black holes are objects with extremely strong gravitational forces that bend spacetime around them. The region from which nothing can escape, not even light, is called the event horizon. Anything that crosses the event horizon is effectively trapped within the black hole and cannot be observed from the outside.

However, if we consider the scenario where you approach a black hole from a safe distance without crossing the event horizon, it is possible to "orbit" or move around the black hole. In this case, it's important to understand that the view of the black hole will change as you move around it. As you move towards the backside of the black hole, the gravitational lensing effect caused by the black hole's gravity will distort the light coming from objects behind it. This effect can cause significant bending and warping of light rays, making the view from behind the black hole highly distorted and potentially unrecognizable.

It's worth noting that the description above assumes a non-rotating, or static, black hole. In reality, black holes can also have spin, which introduces additional complexities to their behavior. For rotating black holes, a phenomenon known as frame-dragging occurs, where the spacetime around the black hole is dragged along with its rotation. This effect further complicates the notion of "going behind" a black hole.

Overall, while it's theoretically possible to move around a black hole without crossing the event horizon, the extreme gravitational forces and warping of spacetime near the black hole would make the view from behind highly distorted and challenging to observe.
