How is it possible that protons and electrons never decay?

250 views

Logically speaking, this seems like an impossible concept to grasp. We see and expect things all things to eventually come to an end, from the mightiest stars to the smallest living things.

How is it possible that certain particles will never, ever lose pieces of their mass or become smaller over time? How can they last forever?

Proton decay is actually currently being studied as a possibility.

A Proton decay has never been observed in the lab but some current estimates put the Half-life at around 1.67×10^34 years (1 with 34 zeros behind it) so a very very long time

Electrons meanwhile are elementary particles meaning that they have nothing to break down into.
