The Oh-My-God Particle



So I read something really interesting about a particle called the “Oh-My-God particle”. Detected on October 15th, 1991 the particle was a proton that was traveling at nearly the speed of light. In fact it was traveling at 99.99999999999999999999951% of the speed of light. The proton had the energy equivalent of a baseball traveling about 100 kilometers per hour (imagine getting hit in the head and knocked out by a particle too small to see). Even the particles produced in our particles accelerators don’t come close to the energy of this particle; the proton has 40 million times more energy than the highest energy proton produced in a particle accelerator. Particles like this one has been detected multiple times since, but physicists don’t really know where it came from or what accelerated it. Wikipedia said something about spinning super massive black holes and possibly dark matter being the cause, but it quickly got too complicated for me to follow. Anyways I found this really interesting so I thought I would share it!
