What are dark matter particles?

Dark matter particles are invisible friends that help hold galaxies together, just like glue holds paper.

Imagine you're playing with building blocks, each block is a star or a planet. When you build a big tower (like a galaxy), it should be easy to knock over, right? But somehow, the tower stays standing even when there’s not much holding it together. That’s because dark matter particles are like invisible helpers, pushing and pulling everything from behind.

Think of dark matter as kids on a playground who you can’t see, they’re running around and jumping on the swings, but you don’t notice them because they're so small and quiet. These kids (the dark matter particles) are everywhere in the galaxy, making sure things stay together even though we can't see them.

Sometimes scientists use special tools to catch glimpses of these invisible helpers, kind of like using a net to try to catch a ghost. They don’t always get caught, but when they do, it helps us learn more about what makes our universe tick!
