On October 15, 1991, the fastest particle ever so far was detected that made many astrophysicists go “OMG!”.
This sounds like funny science fiction, but this actually happened.
This discovery was such a surprise that the scientists in charge of naming this phenomenon decided that they had no other choice than to name it the “Oh-My-God particle”.
Though many faster particles have been found in later years, the wave of surprise of the discovery of the OMG particle was one of the events that gave scientific research a much needed motivational boost.
