Using Gamma-Ray Bursts to Probe Large Scale Structures

Gamma-ray bursts are the most powerful events in the Universe, briefly outshining the combined light of their entire galaxies. A team of astronomers has figured out a clever technique to use the light from gamma-ray bursts to map out the large-scale structure of the Universe at different ages after the Big Bang. They found that the Universe might be less uniform at large scales than previously thought.
