The Mystery of the Oh-My-God Particle

In 1991, scientists detected a single subatomic particle traveling with the kinetic energy of a baseball thrown by a professional pitcher. It is the most energetic cosmic ray ever recorded, shattering all laws of physics.

This mysterious particle packed so much punch that it moved at nearly the speed of light. Its sudden appearance left researchers stunned because nothing in our known universe should be powerful enough to accelerate a particle to such extremes. We still do not know exactly where it came from or what kind of cosmic event could launch something so tiny with such incredible force. It remains one of the greatest unsolved puzzles in astrophysics today.
