ELI5: Explain Like I'm 5

WISP (particle physics)

Particles are tiny little things that make up everything around us, like the air we breathe and the grass we walk on. One type of particle that scientists study is called a wisp.

A wisp is a kind of particle that doesn't have any electric charge, which means it doesn't attract or repel other charged particles like magnets do. Instead, wisps are super sneaky and hard to catch because they hardly ever interact with other particles at all! They're kind of like shy little ghosts that just float around quietly.

In fact, wisps are so shy that scientists can't just spot them with their eyes or a microscope like they can with some other particles. Instead, they have to use really special machines called particle detectors to try and catch a wisp in action. These detectors are like big cameras that can take pictures of particles as they fly by at incredibly high speeds.

When a wisp does get spotted, scientists can learn a lot about how they behave and react with other particles. Studying wisps and other particles helps scientists understand the fundamental building blocks of the universe, and can lead to lots of cool new discoveries and inventions.
