Astrophysicists Jon Hakkila of the College of Charleston and Robert Nemiroff of the Michigan Technological University have published research indicating that blasts that create gamma-ray bursts may actually exceed the speed of light in surrounding gas clouds, but do so without violating Einstein's theory of relativity.

Hakkila and Nemiroff propose that such superluminal jets could create the time-reversibility seen in gamma-ray burst light curves. These proposed jets, however, do not violate Einstein's theory of relativity because they only move faster than light does through the jet medium, not faster than light through a vacuum.

Hakkila - Way - Motion - Someone - Side

Hakkila says that a good way to visualize this superluminal motion is to imagine someone on one side of a pond skipping a stone across the water in your direction. The frequently-hopping stone moves through the air...
