Electrons are the subatomic world’s ultimate survivors—and their lifespan is almost impossible to imagine. Scientists estimate that an electron can live for at least 66,000 yottayears, which is billions of trillions of times longer than the current age of the universe. Even the 13.8 billion years since the Big Bang feels like nothing compared to how long an electron can exist.
This extreme stability is actually the reason everything around us stays intact. Electrons help keep atoms stable, and without them lasting this long, matter itself wouldn’t hold together. In simple terms, if electrons didn’t survive this long, the physical world as we know it wouldn’t exist.
The reason behind this is one of physics’ most important rules—conservation of charge. Since the electron is the lightest particle with a negative charge, it has nowhere to decay without breaking the laws of physics. That means it basically has no natural way to disappear.
Scientists using advanced experiments like the Borexino detector have never observed an electron decaying. Because of this, many experts believe electrons might actually be immortal, making them one of the most reliable building blocks of our universe.
