Perseus–Pegasus Filament

Perseus–Pegasus Filament is a galaxy filament containing the Perseus-Pisces Supercluster and stretching for roughly a billion light years (or over 300/h Mpc). Currently, it is considered to be one of the largest known structures in the universe.[1][note 1] This filament is adjacent to the Pisces–Cetus Supercluster Complex.[2][3]

Discovery

The Perseus–Pegasus Filament was discovered by David Batuski and Jack Burns of New Mexico State University in 1985.[3]

gollark: So it doesn't end up simpler.
gollark: Well, yes, but the kernel has to do branching based on the file descriptor type anyway.
gollark: I mean, which is simpler? `add(x, y) and sub(x, y)` or `perform_arithmetic_operation("add", x, y) and perform_arithmetic_operation("sub", x, y)`?
gollark: It doesn't seem like it's actually simpler though.
gollark: But what's the actual *benefit* of doing so?

Notes
  1. The reference cited claims the Perseus-Pisces Filament as the largest known structure in the universe. However, various reports cite the Hercules-Corona Borealis Great Wall as the largest at 10,000,000,000 light-years (3.1×109 pc) across.
