“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,” Professor Hakkila said. These proposed jets, however, do not violate the Einstein’s relativity because they only move faster than light does through the jet medium, not faster than light through vacuum. Michigan Technological University’s Professor Robert Nemiroff and Professor Jon Hakkila from the College of Charleston propose that these jets could reach superluminal speeds and create the time-reversibility seen in light curves of the gamma-ray bursts.
Others happen when two neutron stars, superdense remnants of stellar explosions, merge.īoth kinds of cataclysmic events create jets of particles that move near the speed of light. Most occur when some types of massive stars run out of fuel and collapse to create new black holes. Gamma-ray bursts are the most luminous explosions in the Universe.
