The structure also contradicts theories about the evolution of the universe. The structure is 10 billion light-years away, which means that we see the structure 10 billion years ago, when the universe is only 13.8 billion years old, and its light was just approaching us. The 3.8 billion year span of time is "too short for a giant structure 10 billion light-years long to form". Even Istvan Horvath, the discoverer of the structure, says he has no idea how the structure has formed in that amount of time. For now, the existence of the structure is still a mystery for cosmologists.
