The discovery of the Hercules–Corona Borealis Great Wall contradicts a theory proposed by Albert Einstein known as the cosmological principle. The cosmological principle says that the entire universe is approximately equal; any two regions in the universe will look very similar, even if those two regions are very far apart, assuming those regions have sizes larger than 250 to 300 million light-years. Maximum sizes of structures must be around 1.2 billion light-years based on the meaning above, and no structure must be larger than that, assuming that matter is spreaded equally from the Big Bang. However, the structure, is eight times larger than the limit, contradicting the cosmological principle.
