Electron Lifetime Is At Least 66,000 Yottayears

Physicists have recently deduced that electrons only manage to stay around for 660,000,000,000,000,000,000,000,000,000 years.

The best measurement yet of the lifetime of the electron suggests that a particle present today will probably still be around in 66,000 yottayears (6.6 أ— 10 to the 28th power), which is about five-quintillion times the current age of the universe. That is the conclusion of physicists working on the Borexino experiment in Italy, who have been searching for evidence that the electron decays to a photon and a neutrino; a process that would violate the conservation of electrical charge and point towards undiscovered physics beyond the Standard Model.
