In my story, there is a 10 meter wide room with a 'special box' in the middle. The box is represented in the picture with the blue outline.
The box is 2.5 meters wide. So when you measure from the left wall of the room to the box, you should get 3.75 meters.
What makes the box special is that, when you measure the distance, you get 5 meters instead. The same phenomenon is observed when you measure the distance between the right wall and the right side of the box. It is also 5 meters instead of being 3.75 meters. ( The box is 2.5 m in length, 1.5 m in width and 1.5 m in height).
This special box in the story obviously does not take up space, but is still there sitting in the room.
Can you guys suggest what kind of space-time phenomenon/space warping phenomenon/ physics phenomenon , no matter have farfetched, would help create such a phenomenon?
