Imagine you're playing hide and seek in a big park, but you can't see the people hiding, they’re just there, affecting everything around them, even though you can’t spot them. That’s kind of how dark matter works.
Like a Bouncer at a Party
Think about a party where everyone is dancing, but there are invisible bouncers pushing and pulling the dancers, you can see the dance, but not the bouncers. Scientists noticed that stars in galaxies are moving faster than they should be, like dancers who are being pushed by unseen hands.
The Hidden Helper
This means there must be something extra, a lot of it, hiding in space. We call this dark matter. It doesn’t shine or glow, so we can't see it, but it has mass, which affects how things move. It’s like the hidden helper at the party, making sure everything stays balanced and moving just right.
Scientists think dark matter is everywhere, in between galaxies, inside them, even near us, and it makes up most of what's out there!
