Ephemistons

ephemistons are theoretical subatomic particles that exist only for extremely brief periods before decaying into other forms of matter. These particles were first hypothesized in the early 21st century as potential explanations for certain quantum phenomena that could not be accounted for by the standard model of particle physics. The term combines "ephemeral," referring to their fleeting existence, with the "-on" suffix commonly used for subatomic particles. Ephemistons are believed to have masses comparable to neutrinos but with different interaction properties. They are thought to be produced during high-energy cosmic events such as supernovae or black hole mergers, though they have never been directly observed due to their extremely short lifespans, estimated to be less than 10^-23 seconds. The study of ephemistons remains largely theoretical, with researchers proposing various detection methods that could potentially confirm their existence. Some theoretical models suggest that ephemistons might play a role in dark matter interactions, though this connection remains speculative.
