The gammaray burst galaxy is a large galaxy filled with gamma ray bursts. The size is difficult to measure; various techniques lead to it either being 250 billion light years, filling a few Hubble volumes, or a googol Planck lengths, being much larger than the Imaginary Dodecahedron.

It is believed that this mismatch in scale it what causes the gamma ray bursts; photons travelling through the galaxy find themselves radically altered in wavenumber and frequency as they travel.
