Protonium

So, have you ever heard of protons? Protons are tiny little particles that are in the center of an atom, and they have a positive charge. And sometimes, two protons can come together and kind of stick to each other. That's called protonium!

Think of it like two magnets that are stuck together because the positive sides are touching. But instead of magnets, it's protons!

Scientists have been studying protonium for a long time because it's really interesting. They want to know more about how it works and what happens when it gets really hot or really cold.

But even though it sounds simple, there's actually a lot more to learn about protonium. Scientists are still figuring out all the different things that can happen when protons come together, and they're always discovering new things about this tiny little particle.
