There are more difficult questions than each other here. It is almost impossible to answer all of them correctly. That's why I will say my thoughts on this topic in general.
Twisting the space-time curve does not make an object inaccessible, only visually invisible. The most effective method known to bend the spacetime curve is to create an intense magnetic field around an object. In this case, the space-time curve bends around the object and travels around it without touching it. In such a situation the object seems inaccessible because it cannot be seen.
I want to illustrate this to you by a drawing in order to show how it works:
You cannot reach the target object visually or physically here. Because when you move towards here, the space-time curve guides you outward. In the meantime, while you think that you are going straight, the road actually got longer. This situation is also the way to reach the middle object. In other words, if an object gives different results when you measure its distance from two seemingly equal places, it is understood that it is there.
This can be found more easily by following the increase in the strength of the magnetic fields by using an Electromagnetic Field Meter.
