An electron is uncrushable.? Can an electron decay?
It doesn't decay (that is, spontaneously change to another form of matter or energy), but it can interact with other particles to become something else, including energy if interacting with a positron. I don't think we can say whether it's uncrushable* , but it's certainly mutable.
