With a length of 428 megaparsecs, or around 1.39 billion light-years, the superstructure is the biggest ever spotted.

Scientists have come up with a number of possible explanations. One of the leading concepts is the ‘cosmological constant’ theory, in which the energy of empty space itself causes cosmic acceleration.
