A Feedback Sphere is a one dimensional object that contains the entire starting universe of Everything. Although they are universes, they are not all of the existance in Everything due to the nested nature of the game. 

Where Found

They are found inside the Quantum Level .

Other Info

Despite being called a 1d object, the ripple design suggests a circular structure, which is actually 2d instead of 1d. Feedback spheres do not appear to exist in real life, so no standard can be made from them. A feedback sphere appears to be an entire universe represented as ripple in time.
